What is a yeast infection or vaginal candidiasis?

According to the Mayo Clinic, a vaginal yeast infection (also called vaginal candidiasis) is an inflammation of the vagina (a type of vaginitis). Symptoms of a yeast infection include intense vaginal itchiness, vaginal irritation, and vaginal discharge. A vaginal yeast infection affects your vagina and the tissues at the opening to your vagina (vulva).

Treating a current yeast infection with boric acid

Recurrent vulvovaginal candidiasis (VVC) or recurrent yeast injections may be difficult to treat. According to the Journal of Women’s Health (2011), “boric acid is a safe, alternative, economic option for women with recurrent and chronic symptoms of vaginitis when conventional treatment fails”.

UW Medicine recommends inserting one boric acid capsule or boric acid suppository vaginally each night before going to bed, for a two-week span or as recommended by your care provider.

Boric acid, a chemical with mild antiseptic, antifungal, and antiviral properties, is another option. In one study of 92 women with chronic yeast vaginitis that had failed to respond to treatment with over-the-counter or prescription antifungal medicines, 98% of the women successfully treated their infections with 600 mg boric acid capsules inserted into the vagina twice per day for two-to-four weeks.

How to prevent recurrent yeast infections with boric acid

According to an article in UW Medicine’s website, after completing treatment for a current infection, continue to place the boric acid capsules in the vagina two nights in a week for six to 12 months or as recommended by your provider.
