Progesterone Congeners

Oral contraceptives are pills that prevent pregnancy. Most oral contraceptive pills contain 2 hormones—estrogen and progestin—that are naturally present in the bodies of individuals who are capable of becoming pregnant. Progestin-only oral contraceptive pills can be used by individuals who should avoid additional estrogen, such as those who smoke, are breastfeeding, or have heart disease or diabetes.

In the US, nearly all oral contraceptives require a prescription. In July 2023, the US Food and Drug Administration (FDA) approved the first oral contraceptive pill (Opill) that will be available without a prescription.
