Boric acid suppositories are an over-the-counter medication used to treat yeast infections and other kinds of vaginal problems that don’t respond to antibiotics. They can also help prevent recurrent infections, says Kecia Gaither, MD, an ob-gyn in New York City.

Yeast infections are common, and most women have one or more at some point in their lives. They can cause itching, redness, and discharge. These symptoms are also more common in women who are pregnant or have a weak immune system, such as those with HIV/AIDS.

If you have a yeast infection or other vaginal problem, talk with your doctor about treatment options. They may suggest a boric acid vaginal suppository or other treatment.

Before using boric acid, read the drug label and instructions carefully. Some products come with applicators, while others require you to insert the suppository yourself.

Then, use the suppository once daily by inserting it into your vagina, according to product directions. If you have trouble insertion, ask your pharmacist for tips.

It’s important to keep your hands clean when you insert the suppository. The medicine can leak out if you contaminate your hands with bacteria, so wash them before you use it.

Some people get a burning sensation when they insert the suppository into their vagina, but this is not a serious side effect. It usually goes away after you stop using the suppository.

Boric acid suppositories are not safe for people with diabetes, high blood pressure, or a weakened immune system. They can also cause bleeding. So, talk to your provider before taking them if you have any of these conditions or if you’re currently taking any medicines that thin your blood.
