lactic acid + citric acid + potassium bitartrate

**Lactic acid + citric acid + potassium bitartrate** is a prescription, non-hormonal contraceptive vaginal gel marketed in the United States as **Phexxi** for prevention of pregnancy in females of reproductive potential. Developed by **Evofem Biosciences**, it is a combination small-molecule drug product administered intravaginally using a pre-filled applicator immediately before, or up to one hour before, each act of vaginal intercourse. Its contraceptive effect is achieved by maintaining the vaginal environment in an acidic pH range that is inhospitable to sperm and reduces sperm motility, rather than through systemic hormonal activity or a specific molecular receptor target. The product is minimally systemically absorbed and common adverse reactions include vulvovaginal burning, pruritus, urinary tract infection, and bacterial vaginosis.
