Generic Prometrium (Progesterone)
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.This medication is not for use in children.
WARNINGS: Progesterone is sometimes used with another medication (a type of estrogen) as combination hormone replacement therapy (HRT) in women after menopause. Combination HRT can rarely cause very serious side effects such as heart disease (e.g., heart attacks), stroke, serious blood clots (e.g., in the lungs and legs), dementia, and breast cancer. Some of these risks appear to depend on the length of treatment and other factors. Therefore, combination HRT should be used for the shortest possible length of time at the lowest effective dose so you can obtain the benefits and minimize the chance of serious side effects from long-term treatment. Combination HRT should not be used to prevent heart disease or dementia. Discuss the risks and benefits of treatment and your personal health history with your doctor. If you take combination HRT, check with your doctor regularly (e.g., every 3-6 months) to see if you still need to take it.
If you use this medication for an extended period, you should have a complete physical exam at regular intervals (e.g., once a year) or as directed by your doctor. See Notes section.
