Boric Acid

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 recommends using capsules that each contain 600 mg of boric acid once a day for 2 weeks.
