Boric Acid Suppositories for Vaginal Health

• Side Effects

Boric acid suppositories are a cost-effective alternative treatment method that may be used to treat vaginal infections, such as yeast infections or bacterial vaginosis .

They may be prescribed by your healthcare provider as an alternative or adjunct treatment option if other methods, such as antibiotics, aren't helping or if infections are recurring. They are also available over-the-counter.

This article discusses what boric acid suppositories may be used to treat. It will also cover benefits and risks associated with using them.

Boric acid suppositories are not FDA-approved. It's important to speak with your healthcare provider before using them to treat any vaginal infection.

Benefits of Boric Acid Suppositories

Boric acid may help improve vaginal health and has been shown to have anti-microbial and anti-fungal activity.

Research suggests that when used appropriately, boric acid suppositories can help reduce the risk of recurrent infections. At times, boric acid suppositories work more effectively than traditional medications, like some antifungals, which are used for treating yeast infections.

Boric acid may be recommended in some cases for:

• Yeast infections
• Trichomoniasis
• Bacterial vaginosis

Boric Acid for Yeast Infections

There is reasonably good evidence for the use of boric acid suppositories to treat yeast infections. That is particularly true for people whose yeast infections are not caused by Candida albicans , the usual culprit for yeast infections.

A review of studies found that:

• Boric acid did a reasonable job of eliminating such non-albicans infections and was able to cure between 40% and 100% of such yeast infections.
• The treatment was generally considered safe with only mild side effects.
• Yeast infections were no more likely to recur after boric acid treatment than after the use of standard antifungal drugs, such as miconazole.

Yeast infections are a common vaginal health condition that can lead to symptoms like vaginal itching, redness, and discharge. Vaginal colonization by Candida , the most common form of yeast associated with vaginal infections, is estimated at 20%. This number goes up in late pregnancy as well as in people who are immunosuppressed , such as those with advanced HIV .

A healthy vagina is naturally acidic which reduces the growth of many pathogens, like those commonly associated with sexually transmitted infections . When the pH is disrupted, you may be more prone to vaginal infections and irritation.

Boric Acid for Trichomoniasis

There is some evidence that boric acid suppositories can be used to treat trichmoniasis, a sexually transmitted infection caused by Trichomonas vaginalis. However, there isn't a lot of research and studies tend to be small.

That said, laboratory-based studies have shown that boric acid can effectively inhibit the growth of trichomonas. This supports the idea that boric acid may be an appropriate treatment option for this condition.

Trichomonas has difficulty growing in acidic environments in lab settings, and infections have been shown to occur more frequently in people who have a higher than healthy vaginal pH. If your infection has been difficult to treat, it may be worth discussing boric acid suppositories with your healthcare provider.

Just be aware that sexual partners need to be treated for trichomoniasis as well, and you should practice safe sex until treatment has been successful. Otherwise, there is a risk that you could pass an infection back and forth.

Boric Acid for Bacterial Vaginosis

There is little evidence for the use of boric acid to treat bacterial vaginosis (BV) , a condition that occurs when there is an imbalance in the vaginal flora. However, small studies suggest that it can be an effective treatment when used alone or as an adjunct therapy.

In a study, about 77% of participants reported feeling satisfied with how their symptoms resolved, however, the average treatment time was a little over a year.

BV is not generally thought of as a sexually transmitted infection. However, it and other forms of non-infectious vaginitis (such as yeast vaginitis) may still be associated with sexual activity.

How to Use Boric Acid Suppositories

Before you use a boric acid suppository, make sure you wash your hands thoroughly. Use an applicator or your finger to insert one suppository into your vagina in the evening. Consider wearing a panty liner or washable period underwear as there may be discharge.

Typical treatment for a yeast infection includes leaving one suppository in overnight for seven days. For recurring yeast infections , insert one suppository per evening for 14 days, then continue use for six months to a year twice a week.

How long you should use boric acid suppositories can vary and should always be discussed with your healthcare provider.

Side Effects and Risks

Using boric acid suppositories can come with risks. Always tell your healthcare provider about other medications and supplements you are taking, as these could interact with the suppository. Never take boric acid suppositories orally and don't use if you are pregnant or plan on becoming pregnant.

Side effects and risks associated with boric acid suppositories may include:

• Vaginal irritation and burning
• Medication leaking out and not fully absorbing
• Harm to fetus
• Toxic effects if too much is absorbed which can lead to kidney damage , circulatory system failure, and even death

A Word From Verywell

Alternative remedies range in quality. Some are heavily researched, well understood, and known to be effective. Others have no evidence behind them, just a lot of marketing dollars.

The quality of the evidence for the use of boric acid in vaginal health is moderate. There have been a number of human studies and in vitro studies showing its effectiveness.

The evidence has not always been consistent, but it is strong enough to suggest that boric acid treatment may be a safe, reasonable option for treating some vaginal health problems. In particular, it may be worth consulting with your healthcare provider about trying boric acid suppositories when standard yeast, BV, and trichomoniasis treatments have failed.

How to Use Boric Acid Suppositories: Ultimate Guide

For many women, vaginal yeast infections are an ongoing reality - they’ve seen professionals seeking medical advice for their vaginal health, tried at-home remedies, and bought numerous products meant to assist in controlling yeast infections but only ended up making them worse. We believe women should be empowered to make what they feel is the best decision for their own care, and providing women with options is key to achieving this.

That’s why pH-D created the first Vaginal Boric Acid Suppositories available to women in 2014. pH-D Feminine Health’s Boric Acid Suppositories are a holistic, accessible, affordable, doctor recommended solution for vaginal yeast infections. Yeast infections are one of the most common feminine care concerns women bring to their healthcare providers, and our goal is to normalize the conversation so it isn’t something women think they should feel embarrassed or ashamed about.

What are   Boric Acid Suppositories ?

Boric acid is a natural compound found in seawater that has been used by healthcare providers for hundreds of years as a holistic solution for vaginal yeast infections. In its purest form, boric acid is a white powder that is both colorless and odorless. Boric acid is a common and safe ingredient used in a variety of cosmetic products as well as feminine care products to help control vaginal yeast infections.

pH-D Boric Acid Suppositories come in a small capsule that look like a pill but are   NOT FOR ORAL CONSUMPTION.   The capsules are clear, and the boric acid powder contained inside the capsule is white. Although boric acid can be harmful if swallowed, it can be safely used by many women as a solution for vaginal yeast infections.   If you are pregnant, trying to conceive or breastfeeding, you should not use   boric acid . Discontinue use immediately if you become pregnant.   Keep in mind that you should never use a boric acid vaginal capsule or other similar suppositories if you have sores, open wounds, or if you have a sensitivity or allergy.

Using Boric Acid Suppositories: The Basics

Your first time using a Boric Acid Suppository can be a bit daunting, and you likely have a few questions. But by the time you’ve successfully used them once, you’ll be plenty comfortable. Here are some basics on how to use the suppositories, how often to use them, and the kinds of activities you should and shouldn’t do while using them:

• The suppository should be inserted into the vagina and will dissolve inside the vagina within 4-12 hours.
• We recommend inserting one suppository at night. We recommend wearing a panty liner, especially when using during the day as there may be watery leakage.
• Each pH-D Boric Acid Suppository contains 600 mg of boric acid which is the amount recommended by doctors.
• Some women may experience mild burning or irritation. This may occur if the suppository was not inserted far enough into the vagina or if you have any irritated or open skin within the vagina.
• A small percentage of women experience spotting when using boric acid suppositories. It is safe to continue use if you are comfortable doing so. However, if it worsens or you begin to experience burning or irritation, we recommend you discontinue use.
• You can have sexual intercourse (including oral sex) after using boric acid suppositories. However, it is important to make sure the suppository has completely dissolved before doing so to avoid mild skin irritation. It can take anywhere from 4-12 hours to dissolve, but each woman is individual, and times may be longer or shorter.
• The boric acid may in fact break down a condom, so we recommend making sure the suppository has completely dissolved before having sex. This can take anywhere from 4-12 hours, but each woman is individual, and times may be longer or shorter.
• We are not aware of the potential impact boric acid may have on your hormonal vaginal ring and its effectiveness. Please consult your healthcare provider or the manufacturer of your hormonal vaginal ring.
• pH-D boric acid suppositories are safe to use with an IUD.
• It is safe to use boric acid suppositories while on your period, but if you are not comfortable, you can wait until your period is over to use them again.

How   To   Insert Boric Acid Suppositories?

• Wash your hands thoroughly to ensure they are clean
• Take one vaginal suppository and insert it into the vagina like you would a tampon.
• You can insert the suppository standing up with your feet spread apart or by lying on your back with your knees bent. Using your fingers, insert the suppository into the vagina and push it up until you can’t feel it anymore.

Why Should I Use   Boric Acid Suppositories ?

Vaginal yeast infections can be a concern to some, but it is actually common among women of all ages. Vaginal yeast infections can be caused by a multitude of activities, including, but not limited to the following:

• After exercising  and sitting in sweaty clothes
• Wearing a wet swimsuit for an extended period of time
• Wearing tight pants and clothing that is not breathable
• Using scented detergents on underwear
• Stress and anxiety
• Changes in diet or sugary foods

Many women will try to mask or get rid of vaginal yeast infections by using heavily fragranced soaps or washes, douching, or even spraying perfume on their underwear. Some women are embarrassed to discuss their concerns with their gynecologist or simply may not have access to healthcare. Boric acid vaginal suppositories are an effective, affordable, and holistic solution for yeast infections. They are easy to insert and an accessible over the counter solution to yeast infections.

pH-D Boric Acid Vaginal Suppositories   are the #1 Doctor recommended brand of boric acid vaginal suppositories with over 10,000 clinics recommending pH-D Boric Acid Suppositories to their patients. Take on each day feeling your most confident and comfortable!

Boric Acid Suppositories Can Help Prevent Recurrent Yeast Infections And Bacterial Vaginosis

And they're available over-the-counter.

A quick refresher: “The vagina is pretty incredible because it has mechanisms to maintain its pH in a healthy acidic range of 3.8 to 4.5,” explains Alyssa Dweck, MD , ob-gyn and founder of V-qool in Westchester County, New York. Healthy, "good" bacteria called lactobacilli that are naturally in the vagina produce lactic acid to maintain this pH, Dr. Dweck explains. "And many daily practices or infections can disrupt this pH and cause symptoms such as itching, irritating, odor, abnormal discharge, and infection with yeast or other bacterial overgrowth.”

Now let's get to boric acid (or boriseptic) suppositories. These are often prescribed as an alternative treatment for certain types of vaginal infections that are resistant to standard treatment, says Kecia Gaither, MD , an ob-gyn in New York City, or as a preventative measure. But are they boric acid suppositories legit and, more importantly, safe? Let's dig in.

What are boric acid suppositories exactly?

Boric acid (yes, the same stuff we use to kill cockroaches) can help to maintain a healthy vaginal pH for those struggling with chronic or recurrent yeast or bacterial infections, says Dr. Dweck. It can be formulated in vaginal capsules, but they’re meant only for intravaginal insertion (meaning you put the capsule directly in the vagina) and should never be taken orally.

“Historically, these needed to be prescribed by a health care practitioner and formulated at a specialty compounding pharmacy for individuals,” she explains. “They have since become a bit more mainstream and are available over the counter.”

What are boric acid suppositories used to treat?

Boric acid is usually thought of as a preventative management for those who experience chronic and recurrent yeast infections or bacterial vaginosis (BV), says Dr. Dweck. It is not usually a first-line treatment, but rather used to prevent recurrence after standard treatment or aid treatment of an infection that just won't quit.

How long does it take for boric acid suppositories to work?

Since boric acid suppositories are generally used as a preventative method, after standard treatment should have already been attempted, says Dr. Dweck. After you've finished the original course of treatment recommended by your doctor, there are many regimens you can implement that involve these suppositories to prevent a recurrent infection.

"My go-to regimen is one suppository (500 to 600 mg) intravaginally once per week for eight to 12 weeks,” she says. “ I usually use this after satisfactory treatment with a traditional antifungal/antibiotic, and this is usually sufficient for prevention.”

Is it safe to use boric acid suppositories on your own for vaginal issues?

If traditional treatments aren't helping you kick recurring infections, definitely talk to your doc about trying out this alternative method before you go at it alone to make sure you do so safely.

You should *always* avoid oral use of boric acid because the substance is toxic when ingested. So, this also means you should avoid receiving oral sex after insertion for at least 24 to 48 hours, says Dr. Dweck. Additionally, if you find you’re sensitive to boric acid or the capsule it’s contained in, then she recommends discontinuing use (though Dr. Dweck notes this is rare!).

“Potential side effects include redness, burning, and watery discharge,” adds Dr. Gaither. “Boric acid suppositories should also not be used during pregnancy or in the presence of open wounds.”

Lastly, you should always obtain these capsules from a reputable pharmacy, Dr. Dweck says.

The bottom line: Boric acid suppositories may help prevent recurrent yeast or bacterial vaginosis infections after you've completed standard, doctor-recommended treatment.

Vaginal boric acid fact sheet

Boric acid, often misunderstood due to its use as a pesticide, plays a crucial role in treating vaginal infections by inhibiting the growth of bacteria and fungi. This guide demystifies boric acid, highlighting its safety, effectiveness, and the scientific backing behind its use for vaginal health. Understanding the difference between boric acid, boron, and borax is essential, as is recognizing the precautions to ensure safe use, especially regarding its non-toxicity at appropriate doses and its bacteriostatic and fungistatic actions.

There is a lot of information about boric acid online for use as both a pesticide and a vaginal application. This can make it seem scary to use in your vagina.

Before you use boric acid vaginally, it pays to understand how boric acid works on bacteria and fungi cells. Boric acid does kill some insects, but only insects that groom themselves. This is why it’s useful as a pesticide. You can think of boric acid more like salt than anything else – it looks like salt and is considered as non-toxic as salt.

How boric acid works to kill bacteria, fungi, and some insects

Insects that groom ingest the boric acid on their body, and it overwhelms their system and they die. If an insect doesn’t groom, boric acid does not affect them. In some bacteria and fungi cells, boric acid affects the cell wall in a negative way, causing either the microbe to die or to disable its reproductive abilities. ​1​

If a microbe can’t reproduce itself, then once it dies, that’s it. Game over. This means your vaginal symptoms will last as long as it takes for that microbe to die. Most microbes don’t have a very long lifespan, so often boric acid tends to work quite quickly.

Is boric acid poisonous?

Boric acid is not poisonous in the usual sense, just like salt isn’t poisonous in the usual sense, but it can be toxic if used incorrectly and in high doses for a long period of time.

There is a great deal of research into boric acid vaginally, and gynaecologists may prescribe it if other yeast infection treatments don’t work. Boric acid is a useful tool to have in your arsenal against vaginal infections of any kind.

How does boric acid work?

Boric acid promotes an acidic environment (which our good bugs like) while also having a bacteriostatic action against pathogens. Bacteriostatic means that it stops the microbe from reproducing, but may not kill them outright.

Don’t overuse boric acid – stop vaginal treatments when your symptoms go away, unless otherwise told by a healthcare professional as part of a greater plan. It can pay to do an extra day or two to make sure whatever was in there is gone, but play it by ear and see how you go.

It’s pretty hard to do boric acid wrong, so long as you only do one treatment per day, and don’t do it for months at a time. Do not eat boric acid.

You can buy boric acid cheaply – don’t pay a lot for boric acid, as it is an inexpensive product.

Medical scientists have studied the use of boric acid in the vagina and have recommended its use in a limited capacity.

Boric acid is not an alternative medicine practice,  per se . You are just as likely to be recommended boric acid vaginally by your gynaecologist as your naturopath.

Understanding boric acid, boron and borax

To understand boric acid, we first need to establish the difference between boric acid, boron, and borax.

Naturally-occurring mineral mined from dry salt lakes. Mined just like regular salt. Comes in four forms, four boron atoms, plus two sodium atoms, and varying amounts (including zero) of crystallisation water (oxygen and water). ​2​

Usually sold pure or almost pure. In the stomach, borax reacts with hydrochloric acid and forms boric acid and sodium chloride. The boron content of borax is about 11.3 per cent. All borax is the same, like salt is – it is mined and then sold.

There is no pharmaceutical grade or agricultural grade or food grade. Some people use diluted borax for its boron content as a food supplement in small doses.

Boron is a chemical element, and a part of borax and boric acid. Boron is present in fruit and vegetables, and is a part of healthy soil. You can be deficient in boron.

Each day, people who eat a lot of fruit and vegetables would ingest between two and five milligrams of boron per day, but most of us would be sitting at about one or two milligrams per day. Poor soil and overcooking means less boron.

Boric acid contains 17.5 per cent boron. Boric acid is non-toxic to wildlife, especially birds and frogs, but mildly toxic to fish, and non-toxic in normal doses for humans.

All borax, boric acid and boron are considered low-toxicity salts. Table salt is a comparable salt. The reason there is so much legislation involving borax and boric acid is that it used to be a food preservative (so we were ingesting it).

Eating it was amongst many other ways that people were getting sick from it, like putting it repeatedly into cuts to act as an antiseptic, where it leached continuously into the blood. This was put to an end in many countries since it presented a public health issue – people were taking high doses for long periods of time.

Borax, boric acid and boron are useful or even essential in our environment and food supply. Boric acid can be used safely – there is a lot of evidence that boron is a very important and useful chemical element that has a bit of a complicated  reputation.

Don’t let the word ‘acid’ scare you off either. It’s a chemical name, similar to ascorbic acid (vitamin C) and acetic acid (vinegar).

Quick warnings on boric acid

• Do not use boric acid if you are pregnant or lactating – no safety data exists (you could swap it out for vitamin C after a chat with your doctor) ​3​
• Do not eat boric acid – toxicity is far greater than vaginally
• Use caution when using boric acid for more than two weeks consecutively (because we don’t know what the impact is, because it hasn’t been studied)

What is boric acid?

Boric acid (also boracic acid, orthoboric acid) is a white, odourless powder that comes in crystals or granules. Vaginal suppositories of boric acid are not commercially available, and so you have to make them up yourself. It is not considered a human or animal carcinogen.

What is the studied vaginal dose?

The dose most studied is 600mg of boric acid powder in a gelatine (veggie) capsule vaginally. Just because it hasn’t been studied, however, doesn’t mean you can’t experiment, but read the research and see what you consider the parameters to be.

How does boric acid work to solve vaginal infections?

Boric acid is a weak topical bacteriostatic and fungistatic, meaning it stops microbes from reproducing, but does not kill them. We’re not sure why exactly this is.

Boric acid is weaker on the pH scale than vitamin C, so the acidity is not the primary mode of action, though it helps. The fungistatic action may be related to acidity, however, since the acidity can penetrate the cell wall of some fungi and disrupt the membrane.

But, studies looking at what the lowest concentration of boric acid is that inhibits microbes show that boric acid works at a pH similar to the untreated vaginal tract, so the acidity theory isn’t particularly strong.

Ingestion and absorption of boric acid

Boric acid, when eaten, is quickly and completely absorbed, and is well-absorbed through unprotected or open skin in both liquid and powder form. Absorption through intact skin is thought to be negligible. Once boric acid is absorbed, it is sent throughout the entire body. When used vaginally, it is absorbed, but not as much as when eaten nor as little when in contact with intact skin.

How boric acid is metabolised and excreted

Boric acid is not really metabolised, and is excreted in its whole form (more or less) by the kidneys. About half is excreted within 12 hours of taking it (the half-life), and 90 per cent is excreted within 96 hours. Very little is excreted in faeces, sweat and saliva.

In the vagina, absorption of boric acid after insertion of one to two 600mg boric acid capsules for one to two weeks in eight healthy volunteers resulted in no volunteer having detectable boric acid levels 48 hours after the end of treatment.

Boron blood levels below 200 pg/ml are considered to be safe by many researchers, with the average blood concentration being about 46 pg/ml in the volunteers during the treatment. This means that any treatment could potentially be about three times greater than a 600mg daily dose and still be considered safe.

One volunteer had her blood boron analysis done after a single 600mg boric acid capsule, revealing about six per cent absorption from the vagina, and a half-life of 10.5 hours. A half-life of 21 hours has been reported after intravenous application in eight healthy males.

Side-effects and interactions of boric acid vaginally

Short courses of intra-vaginal boric acid are generally well tolerated. The most commonly reported side-effects are mild, and include a watery discharge, redness, burning, and a male sex partner feeling grit on his penis during vaginal sex. No drug interactions have so far been reported involving boric acid.

Long-term safety is unknown, so using boric acid for more than one to two weeks at a time has unknown impacts. There is some controversy regarding boric acid due to toxicities, with a problematic occurrence in 1888 (yes, 1888!) where intravaginal treatments caused poisoning after vaginal applications. Studies have not repeated this, so it is unknown what dose was applied.

Risks and symptoms of boric acid toxicity

Toxicity is measured by how much of the element  boron  a product contains. A fatal dose orally is considered to be 20 grams (0.1 – 0.5 mg/kg). Boric acid toxicity affects the digestive tract, central nervous system, skin, liver, and kidneys. ​4​

Symptoms of boric acid toxicity are vomiting, diarrhoea, or abdominal pain, but may extend to over-excitement of the nervous system which is then followed by lethargy and fatigue, headaches, seizures, coma, and high fever. The kidneys are affected. Death can occur within 3-5 days of acute poisoning.

Systemic toxicity and side-effects from vaginal administration

Toxicity caused by vaginal application of boric acid is believed to be minimal, but symptoms might include loss of appetite, digestive problems, weakness, confusion, dermatitis, menstrual disorders, anaemia, seizures and loss of hair (alopecia).

Antimicrobial action of boric acid – how it works

Boric acid has some activity against staphylococci and streptococci, though this is theorised to be bacteriostatic (stops microbes from reproducing, but does not kill them) and slow to occur.

Yeast-killing action of boric acid

Boric acid is most commonly associated with its antifungal activity. ​5,6​ In vitro studies using boric acid concentrations ranging from 0.4 – 5.0 per cent have been found to inhibit  Candida albicans  isolates. A dose of 500mg boric acid has been found to reportedly kill 50 – 90 per cent of  C. albicans  isolates in 48 hours.

Vaginal yeast infections were most often caused by  C. albicans  isolates, however this is changing, and more non- C. albicans  isolates are causing yeast infections. The most common of those is  C. glabrata  isolates, which are resistant to fluconazole and itraconazole, the typical antifungal treatment that works against  C. albicans.

Boric acid may have improved activity against these other yeasts, and has demonstrated efficacy against  C. glabrata  isolates.

Boric acid may also have antifungal activity against  Saccharomyces cerevisiae , a microbe that can cause vaginitis.

Gynaecologists may recommend boric acid as a safe home remedy for treating vaginal yeast infections.

Borax and boric acid as an insecticide, pesticide and herbicide

Boric acid’s impact on insects varies, since only insects that groom are affected. The insect grooms, and as it does so it ingests boric acid, thus poisoning them and killing them – their little system is not set up to deal with boric acid. Plants dry out in the presence of boric acid, and thus cell death is a consequence.

Many molecules are poisonous to insects and plants, but fine for humans or animals.

Think of the way chocolate can kill a dog, or how mosquitoes hate smoke. Understanding the chemistry of a substance is key to understanding how it will behave when it comes into contact with animals, humans, insects or plants.

It’s science!

If you've already tried anti-fungal creams, ointments, tablets, and suppositories to treat your persistent yeast infection, then you may want to try boric acid, which is an alternative treatment for chronic yeast infections. Boric acid suppositories, capsules that you insert into your vagina, can be used to treat stubborn or resistant yeast infections caused by less common forms of yeast. Whether you make your own capsules or get them from a pharmacy, properly used boric acid suppositories can cure, and possibly help prevent, vaginal yeast infections. Be sure to speak with your doctor or OB/GYN about this method so you understand proper use.

Best Way to Insert a Vaginal Suppository

Wash the outside of your vagina with mild soap and water, then lie on your back and spread your legs apart. Use your fingers or an applicator to gently insert the boric acid suppository into your vagina as far as it will comfortably go. If you’re using an applicator, push on the plunger and then remove the applicator.

Using the Suppositories

• Your doctor can give you a prescription to take to your pharmacy to have capsules made.
• When you go to your doctor, be ready to discuss the history of your symptoms and how they have evolved, including how many yeast infections you’ve had in the past and what is similar and different this time.

• It will help to tell them what you intend to use it for, so they don’t think you’re trying to poison someone! Boric acid is also used to kill rats.

• If you’re using a reusable applicator, clean it as directed by the manufacturer. Otherwise, throw it away.
• If it’s hard for you to insert the suppository while lying down, try standing with one foot propped up on the edge of the bathtub or a chair.
• It’s normal to have some discharge when using suppositories. Wear a panty liner to bed to avoid staining your underwear.

• The first time you use this method, it’s best to consult with your doctor or OB/GYN.

• You can alternate using lactobacillus acidophilus suppositories during the day and boric acid at night. [3] X Research source

Using Boric Acid Safely

• If the powder contacts your skin (other than inside your vagina where it’s meant to dissolve), wash the area thoroughly. [6] X Research source

• If someone else accidentally swallows it, be prepared with the following information when you call for emergency services: The person’s age, weight, and condition (awake/unconscious/vomiting, etc.), how much was swallowed, and what time it was swallowed. [9] X Research source
• In the United States, call 1-800-222-1222 to speak with the poison control center for further tips while waiting for emergency services.

Creating Your Own Capsules at Home

• Boric acid powder should be readily available at most convenience stores such as Walmart, CVS, and Rite Aid. If you cannot find it, a pharmacist can probably order it for you. [10] X Research source
• Look for empty gel capsules at local stores and pharmacies like Walmart, a vitamin or health food store, or order them online.
• You may also want to wear latex or rubber gloves, as boric acid can irritate the skin.

• A capsule should contain around 600mg of boric acid. Fill the capsule with as much powder as it will hold.

• Do not store them in the refrigerator.

Expert Q&A

• Treatment with antifungals (medicines ending in “-azole” like miconazole) is more common for single, uncomplicated yeast infections. [14] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source If this is your first diagnosed yeast infection, first try an over-the-counter medicine like Monistat. Speak to your doctor before using boric acid suppositories. Thanks Helpful 0 Not Helpful 0
• To help prevent future infections, keep your vagina clean and dry. Use unscented soap, take showers instead of baths, wear cotton underwear, avoid tight pants and pantyhose, and always wipe front-to-back after a bowel movement. Thanks Helpful 0 Not Helpful 0
• Avoid sex during your treatment to help clear up symptoms more quickly. Thanks Helpful 0 Not Helpful 0

• Mild burning and skin irritation can occur when using boric acid. Thanks Helpful 13 Not Helpful 2
• Do not use boric acid suppositories if you are pregnant or might be pregnant. Thanks Helpful 7 Not Helpful 0
• Boric acid is toxic if taken orally. Thanks Helpful 7 Not Helpful 2
• Never use boric acid on children. Keep capsules away from children to prevent accidental ingestion. Thanks Helpful 4 Not Helpful 2
• Always consult your doctor before using any at-home remedies. Thanks Helpful 4 Not Helpful 2
• Do not use more boric acid capsules than prescribed, and do not use more than one per day. If your body absorbs too much of it you can get kidney failure or serious problems with your circulatory system that can be fatal. [15] X Research source Thanks Helpful 0 Not Helpful 0

Do boric acid suppositories and washes work for bacterial vaginosis or yeast infections?

Lately, people on social media have been pushing the benefits of boric acid use as an at-home treatment for bacterial vaginosis or BV, and yeast infections. But do the claims live up to the hype? Is it safe?

Sometimes it isn’t always easy to separate fact from fiction regarding home remedies. Here we take a closer look and provide some advice from Nebraska Medicine OB-GYN Katherine Lessman, MD .

Bacterial vaginosis or yeast infection? How to know

BV is a common vaginal infection that causes a bacterial imbalance. When normal vaginal bacteria overgrow, you may or may not notice any symptoms. You may notice vaginal discharge, a strong odor or irritation when you urinate.

A yeast infection occurs when the fungus candida overgrows. Symptoms typically include an itchy or burning sensation in and around your vagina, a thick, white vaginal discharge, vaginal and vulva redness, swelling, or burning while urinating.

What’s the difference?

Both conditions are vaginal infections , and the symptoms tend to trend toward patterns. Symptoms can overlap and can even mimic one another.

• Irritation and burning: BV doesn’t always include these symptoms, but yeast infections do
• Discharge: BV usually has a “fishy” smell. Yeast infections don’t typically have a strong smell but have a cottage cheese appearance

Do boric acid suppositories, or washes effectively treat bacterial vaginosis or yeast infections?

“Boric acid is a relatively simple treatment with a complicated reputation,” says Dr. Lessman. “It can be helpful and even important in a few specific contexts, but it’s rarely a first-line treatment. For yeast and bacterial vaginosis, prescription treatments are the most effective and are actually safer than boric acid.”

Boric acid may be helpful for resistant or recurrent vaginal infections when combined with a prescription antifungal or antibiotic. Most yeast infections are caused by candida albicans, so boric acid may be helpful for the exception – when caused by a less common yeast like candida glabrata. Since you don’t know what type is causing your problem, visiting your doctor for ongoing or reoccurring infections is best.

Are boric acid washes and suppositories safe? There are drawbacks

“Boric acid isn’t well regulated or thoroughly studied,” says Dr. Lessman. “Clinical studies were performed with boric acid suppositories made by compounding pharmacies. The commercially available formulations should be the same, but they haven’t proven that they deliver on their claims. And this is worse for the rinses or washes, whose drug delivery and efficacy is a mystery.” 

Additional downsides:

• Boric acid is highly toxic if swallowed. Suppositories are usually pills that are placed in a body cavity instead of being swallowed, but consuming a single pill can be fatal
• Boric acid can cause dramatic irritation, even to the point of chemical burn. Burns are not expected with daily use but are possible 
• Sexual partners may report skin irritation
• Boric acid is not recommended for pregnant women or those trying to get pregnant. Actual studies are lacking on this point. Still, if a single pill can be fatal to an adult, even a tiny amount that is absorbed vaginally isn’t wise for the health of a developing embryo

Are Boric Acid Suppositories Effective for Yeast Infections or Bacterial Vaginosis?

Boric acid has long been used to treat vaginal issues, but whether it works is yet to determined. Here’s what experts have to say about how to deal with vagina infections, itching, and odor.

Boric acid has been used for over a century to treat different types of vaginal issues, and suppositories of the substance (inserted into the vagina) have long been recommended by ob-gyns and health practitioners as part of a treatment plan for some types of persistent or recurring vaginal infections , such as  yeast infections  and  bacterial vaginosis to relieve symptoms of itching and burning.

“Boric acid suppositories can be a helpful and even important in a few specific contexts, but it’s rarely a first-line treatment,” says Katherine Lessman, MD , an obstetrician and gynecologist at Nebraska Medicine in Omaha. “For yeast and bacterial vaginosis , prescription treatments are the most effective and are actually safer than boric acid.”

Here’s what you need to know about boric acid suppositories and what they should — and shouldn’t — be used for when it comes to your vaginal health and hygiene.

Vaginal Yeast Infections (Candidiasis)

Boric acid is a solid therapy for recurring  vaginal yeast infections when combined with a prescription antifungal, says Dr. Lessman. “The suppositories are effective treatment for infections with atypical yeast species, such as  Candida glabrata  or  Candida tropicalis ,” she explains.

One of the reasons why boric acid isn’t typically first line is because most yeast infections are caused by Candida albicans . “Since you don’t know what type is causing your problem, visiting your doctor for ongoing or reoccurring infections is best,” recommends Lessman.

To treat a recurrent yeast infection, place one boric acid capsule in your vagina nightly before bed for two weeks, or as recommended by your healthcare provider. While the capsules are not harmful to the vagina as a  yeast infection treatment , they should never be taken orally.

Bacterial Vaginosis 

For some women with recurrent bacterial vaginosis , boric acid may be recommended, particularly when taken along with an antibiotic, says Lessman.

Dos and Don’ts of Boric Acid Suppositories

Never take boric acid suppositories by mouth — the medicine is intended only for the vagina.

People who are pregnant or trying to get pregnant should not use boric acid suppositories — even a tiny amount absorbed vaginally could harm a developing embryo, warns Lessman.

• Frequent infections
• HIV or AIDS
• Immune system problems
• An unusual or  allergic reaction  to boric acid, other medicines, foods, dyes, or preservatives

If you’re breastfeeding, check in with your provider before using boric acid suppositories.

Boric acid can have other side effects, says Lessman. “In some women, boric acid can cause dramatic irritation, and sexual partners may report skin irritation,” she says.

Are Boric Acid Washes and Suppositories Effective for Vaginal Odor and Itching? 

Boric acid should not be the first thing you reach for when you’re experiencing itchiness or vaginal odor , says Lessman. Unlike prescription treatments for vaginal infections, boric acid isn’t well regulated or thoroughly studied, she explains.

“Clinical studies were performed with boric acid suppositories made by compounding pharmacies. The commercially available formulations should be the same, but they haven’t proven that they deliver on their claims. And this is worse for the rinses or washes, whose drug delivery and efficacy is a mystery,” Lessman adds

Boric Acid Rinses or Other Cleansing Products May Actually Increase the Risk for Infection 

“The bacterial flora of the vagina is a delicate balance that naturally protects the vagina,” says  Jen Villavicencio, MD , the lead for equity transformation at the  American College of Obstetricians and Gynecologists (ACOG) . “Cleansing the vagina by any means threatens that balance and potentially increases the risk of  vaginal infections , vaginitis, and vaginal injury. If you are struggling with a vaginal issue, consult a healthcare provider with experience in vaginal healthcare.”

What’s more, most of the products that are promoted as a way to “balance out yeast,” and “eliminate odor” are not regulated by the U.S. Food and Drug Administration. Dr. Villavicencio adds that the broad availability of other products that claim to balance  vaginal pH  and provide all-day freshness are also unnecessary, since the vagina is primarily self-cleansing.

What to Do About Vaginal Itching or Stronger-Than-Normal Vagina Odor

All vaginas will create discharge and have a slight odor that can change throughout the month. Everyone’s vagina has its own unique scent, which is normal and natural.

“If someone is experiencing unusual vaginal symptoms, such as itching, increased discharge, or a new odor, seek the counsel of a healthcare professional that can appropriately diagnose the issue and recommend proper treatment. For routine vulvar [vaginal] hygiene, we recommend only the use of water or unscented soaps, and only for external use,” she says.

Diagnosis and treatment is key. Untreated, some vaginal infections with symptoms of odor or itching can lead to serious problems, including  pelvic inflammatory disease (PID) or infertility.

Expert Recommendations for Reducing Vaginal Odor 

Again, vaginal odor is natural, and feminine products such as deodorants or vaginal douches aren’t recommended. If you don’t have an ongoing infection and your vagina continues to have an odor that you consider unpleasant, there are a few things you can do.

• Keep the area clean. Shower regularly and use unscented soap and warm water to clean your vagina. If you get sweaty from a workout (or any other reason), bathe and put on a clean dry outfit as soon as possible. Wet spandex or bathing suits encourage harmful bacteria growth.
• Wear light, breathable clothing. Avoid clothes that are too snug on your vagina, like thongs. Breathable cotton undies are a good choice.
• Stay hydrated. Dehydration can make your pee especially concentrated and smell bad — drinking more water can help. It’s recommended that women drink about 92 ounces of liquid a day — about 11.5 cups.
• Use condoms during sex to reduce your risk of sexually transmitted infections (STIs). An STI can disrupt your vagina’s pH balance and cause odor.

Can You Use Boric Acid for Bacterial Vaginosis (BV)?

A healthcare provider may recommend boric acid suppositories if you get frequent infections.

Boric acid vaginal suppositories are considered safe and sometimes used to treat recurrent bacterial vaginosis (BV) when combined with antibiotics. Though you could use boric acid for BV, you shouldn't do so without talking to a healthcare provider first. Read on to learn more.

What Is Boric Acid?

Boric acid is a white powder derived from the element boron. It has antifungal, antibacterial, and antiviral properties. You can find boric acid as an ingredient in household cleaners and insecticides—or as a pest killer or laundry stain-remover.

Boric acid is also available as an OTC suppository for balancing vaginal pH, bacteria, and yeasts when inserted into the vagina. Some boric acid suppositories also claim to control vaginal odor and contain additional ingredients like aloe and tea tree oil.

However, the U.S. Food and Drug Administration (FDA) does not approve these products. OTC boric acid suppositories are sold as homeopathic products, meaning the FDA has not evaluated their safety and effectiveness.

How Boric Acid Treats Bacterial Vaginosis

BV can be frustrating if you have recurrent infections after antibiotic treatment. Studies show that using boric acid suppositories with antibiotics as a complementary or preventive treatment can help treat some recurrent BV infections.

Research on how effective boric acid is in treating BV is still limited. Additionally, using boric acid suppositories alone probably won't cure your infection.

One review found that combining antibiotic treatment and 300- to 600-milligram (mg) boric acid suppositories twice a week helped treat recurrent BV and yeast infections. Using boric acid suppositories alone was ineffective.

The exact way boric acid works to help treat BV also isn't fully understood. One theory is that it can help eliminate bacteria that cause the infection.

Other BV Treatments

Antibiotics in cream, gel, or pill form are still the most effective BV treatment since they kill the infection. Common effective antibiotics for BV treatment are clindamycin or metronidazole. These antibiotics can be safely used to treat pregnant individuals with BV.

Is It Safe To Use Boric Acid For BV?

For most people, inserting boric acid suppositories into the vagina is safe. You should not use boric acid suppositories if treating BV while pregnant or trying to get pregnant.

Boric acid is harmful if taken orally. Ingesting 30 grams (g) of boric acid is considered toxic—less than the typical 600mg used in boric acid suppositories.

There is no evidence that boric acid suppositories can be poisonous when used vaginally. Possible side effects from boric acid vaginal suppositories include mild vaginal irritation or watery discharge .

Still, always chat with a healthcare provider to make sure it's safe for you to use a boric acid suppository to help treat your BV.

How To Use Boric Acid for BV

If a healthcare provider says you can use boric acid, you can find OTC boric acid suppositories at your local pharmacy or drugstore. Most boric acid suppositories come in 600-milligram doses that you insert once daily for one to two weeks. A healthcare provider may also suggest a different treatment plan based on your case.

To use boric acid if you have BV:

• Wash and dry your hands before inserting a boric acid vaginal suppository.
• With clean, dry fingers—or a provided disposable applicator—insert one capsule into your vagina as far up as comfortable. It can be helpful to lie down with your knees bent or slightly squatting
• Then throw out your applicator if you used one and rewash your hands.

Some folks also like to wear a pad or panty liner to help collect any discharge from the suppository. You will also want to avoid having sex while using boric acid suppositories and treating BV.

Bacterial Vaginosis Prevention

Even though BV is the most common vaginal infection , the exact cause isn't understood beyond bacteria overgrowth. Douching or having new or multiple partners may increase your risk of BV since these activities can disrupt vaginal bacteria. If you're prone to BV, the following may help prevent infections:

• Avoiding douches and scented vaginal products
• Using condoms and dental dams
• Wearing cotton underwear

When to See Your Healthcare Provider

See a healthcare provider if you have BV and start treatment immediately. BV symptoms to look for may include:

• A strong fishy odor
• Unusual white or gray discharge

You'll also want to see a healthcare provider if your BV symptoms don't improve or you experience pelvic pain or a fever. Not treating BV can increase your risk of sexually transmitted infections (STIs). Having BV while pregnant can cause premature birth and low-birth weight.

While BV is not considered an STI, if your partner has a vagina, they may be at risk of BV. They should also visit a healthcare provider to get tested for BV and receive treatment if they have it.

A Quick Review

Antibiotics are usually the first line of treatment for BV. However, there may be a role for boric acid suppositories, a homeopathic product intended for vaginal use. While the research on boric acid for BV is limited, boric acid suppositories may be part of a treatment plan for repeated infections.

While considered generally safe, these capsules can cause mild skin irritation and be fatal if consumed orally. Pregnant people and those trying to get pregnant should not use boric acid suppositories. Talk to a healthcare provider before using boric acid suppositories for BV.

Can boric acid help with a yeast infection?

Doctors may recommend using boric acid for a yeast infection as a second-line treatment when other antifungal medications are not working.

Boric acid works by preventing Candida fungi from growing. This type of fungus supports the development of yeast infections.

Boric acid is available as vaginal suppositories.

In this article, we look at the research behind boric acid as a treatment for yeast infections, its effectiveness, and possible risks.

It is healthy to have small amounts of yeast on the skin and in areas of the mouth, throat, and vagina. Under some conditions — such as when the immune system is weak or when hormones change during pregnancy — the yeast may multiply and cause an infection.

The medical term for a yeast infection is candidiasis . Yeast infections are common and often occur in the vagina. They are frequently caused by Candida albicans ( C. albicans ) or Candida glabrata ( C. glabrata ) fungi.

Boric acid is a white powder or crystalline solid that acts as a strong antiviral and antifungal agent in the body. Research suggests that boric acid restricts the growth of both C. albicans and C. glabrata . It interferes with the yeast’s natural life cycle, preventing it from growing to become infectious.

According to the Centers for Disease Control and Prevention (CDC) , people should use boric acid as a secondary treatment, that is, if other antifungal drugs or ointments are unable to treat the yeast infection or if it recurs.

Boric acid may be able to treat infections that are resistant to first-line treatment. This is usually an antifungal medication, which may involve a single oral dose of fluconazole or a topical antifungal cream. If these do not work, a doctor may recommend using boric acid or another treatment, such as nystatin or flucytosine.

A person can use a gelatin capsule as a vaginal suppository. The CDC recommend using capsules that each contain 600 mg of boric acid once a day for 2 weeks.

Boric acid medications are usually affordable. They are available for purchase over the counter at drug stores or online.

If symptoms persist after using boric acid, speak to a general practitioner or gynecologist .

What does the research say?

Research indicates that boric acid is effective in treating Candida infections, including cases that do not resolve with common antifungal medications. People with recurrent yeast infections may benefit most from boric acid treatment.

Authors of a 2011 medical review report that boric acid is a safe and economical option for people with recurrent or chronic vaginal infections, especially when conventional treatment is ineffective.

Risks and side effects

A growing body of evidence shows that, when a person uses the optimal concentration, boric acid has fewer side effects than standard ointments.

Some common side effects of boric acid use include:

• vaginal discomfort
• a mild burning sensation after inserting the capsule
• watery vaginal discharge
• hives , the medical name for which is urticaria

A person with any of the following should not use boric acid capsules:

• vaginal bleeding
• pelvic inflammatory disease
• any sexually transmitted disease
• heart disease
• a blood vessel disorder

It is important to remember that boric acid is toxic. If a person uses it incorrectly, it can cause a fatal overdose, though this is rare .

Do not take boric acid orally or apply it to open wounds. Consult a doctor before using this medication while pregnant.

How to use boric acid

Boric acid vaginal suppositories are available for purchase. They are solid, oval-shaped capsules that a person inserts into the vagina. They become liquid as they warm up to the body’s temperature.

To treat a Candida infection, the CDC recommend using vaginal suppositories containing 600 mg of boric acid each. A person should use them once a day for 2 weeks.

Always follow the instructions on the medication’s label.

Before using a vaginal suppository, make sure the hands and vaginal area are clean and dry to prevent bacteria from entering the body.

To use a suppository, a person should:

• Fill the applicator and lie on the back with the knees bent or stand with one foot raised on a chair.
• Insert the applicator gently into the vagina.
• Press the plunger to release the capsule.
• Gently remove the applicator.

Some instructions recommend using a suppository before bed. This is because lying down will reduce the risk of medicine leaking out.

It is safe to use suppositories during menstruation. Use menstrual pads instead of tampons, because a tampon could absorb some of the medication.

Yeast infections are common in healthy adults. Researchers continue to look for treatments that have fewer side effects, better tolerability, and lower cost, while being highly effective.

A person can treat vaginal yeast infections with oral medicines, usually antifungals. These require a prescription. Other medications are available over the counter.

Boric acid is a common alternative treatment that doctors recommend if first-line treatment has not worked or if the infection recurs.

People with recurring vaginal yeast infections may benefit from using boric acid capsules. A doctor can advise about the best dosage and how long to use the medication.
