Boric acid for yeast infection is a century-old remedy for yeast infections. It’s often used when other treatments fail to provide relief, especially if you have a recurrent infection (four or more yeast infections in a year).

Is borax harmful to humans?

Treatment with boric acid is safe and effective. It’s available over-the-counter in vaginal capsules and suppositories or by prescription.

It’s a strong antifungal that works to reduce the growth of Candida albicans and Candida glabrata fungi, according to the University of Washington Department of Obstetrics and Gynecology. It’s also very effective against more resistant yeast strains.

A good dose of boric acid in a vaginal suppository has proven to be a reliable and effective way to treat recurrent yeast infections that can’t be cured with antifungal medications. It’s a safe and cost-effective option.

Recurrent yeast infections can be caused by a combination of factors including your microbial flora and health conditions. Taking probiotics is helpful to maintain the balance of your flora in the vagina, which helps prevent yeast from growing.

Yeast infections may be more common in women who are pregnant or are immunosuppressed (have advanced HIV). They can also occur more frequently in people who have diabetes or other health conditions that affect the immune system.

For recurrent yeast infections, your provider will prescribe 600 mg of boric acid in capsules or suppositories. Insert them vaginally once a day for 14 days. Side effects are typically mild, including redness and a burning sensation.
