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.[2][3] As opposed to combined injectable contraceptives, they contain only a progestogen without an estrogen, and include two progestin preparations:[2][3]
