About Boric Acid

Boric acid is used as a vaginal suppository for recurrent vulvovaginal candidiasis, particularly azole-resistant strains (C. glabrata). CDC STI Treatment Guidelines recommend 600 mg vaginally once daily. A 2024 systematic review (41 studies) reports mycologic cure rates of 40–100%. It is NOT for oral use — toxic if ingested orally. Only effective as a local vaginal agent.
