Woman's Health - Gester (Brand name: prometrium)

Common use

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 (e.g., hot flashes). Progesterone is added to estrogen replacement therapy to reduce the risk of cancer of the uterus.

Dosage and direction

Take this medication by mouth, usually once a day at bedtime or as directed by your doctor. If you have trouble swallowing the pills, take with a full glass of water while standing up. Follow the dosing schedule carefully. Ask your doctor if you have any questions. The dosage is based on your medical condition and response to therapy.
