Uses

Progesterone is a type of female hormone (progestin). This medication is similar to the progesterone that your body naturally makes and is given to replace the hormone when your body is not making enough of it. In women who are not pregnant and not going through menopause, this medication is used to restore normal menstrual periods that have stopped for several months (amenorrhea).

Progesterone is also used as part of combination hormone replacement therapy with estrogens to reduce menopause symptoms (such as hot flashes). Progesterone is added to estrogen replacement therapy to reduce the risk of cancer of the uterus.

This medication is not for use in children.

Progesterone must not be used to test for pregnancy.
