Progestogen-only injectable contraceptive
Progestogen-only injectable contraceptives (POICs) are a form of hormonal contraception and progestogen-only contraception that are administered by injection and providing long-lasting birth control. As opposed to combined injectable contraceptives, they contain only a progestogen without an estrogen, and include two progestin preparations:
- Medroxyprogesterone acetate (brand names Depo-Provera, Provera, Depo-subQ Provera 104) – 150 mg (intramuscularly) or 104 mg (subcutaneously) every 3 months
- Norethisterone enanthate (brand names NET EN, Noristerat, Norigest, Doryxas) – 200 mg (intramuscularly) every 2 months
