Depo‑Provera (medroxyprogesterone acetate) — Uses, Dosage, Side Effects & Safety

Drug class: Progestin contraceptive

Overview

Depo‑Provera is a long-acting injectable form of birth control that contains the hormone medroxyprogesterone acetate. It is used to prevent pregnancy and may also be prescribed for certain menstrual disorders, endometriosis-associated pain, and to reduce the risk of endometrial hyperplasia in women taking estrogen therapy. Depo‑Provera works mainly by stopping the ovaries from releasing eggs (ovulation). It also thickens cervical mucus, making it harder for sperm to reach the egg, and changes the lining of the uterus to prevent a fertilized egg from implanting. Key points for patients: Depo‑Provera is given as an injection every 3 months by a healthcare professional. It is highly effective when used on schedule, but may cause changes in menstrual bleeding patterns and can delay the return of fertility after stopping.
