Drug Uses

 Prometrium is a hormone (progesterone) that protects the lining of the uterus, especially in women who are undergoing estrogen therapy. It lowers the risk of estrogen related cancer of the uterus. Some women have problems with the stopping of their menstrual periods because of lack of the hormone progesterone. Prometrium is also helped to treat them.

 How it is taken

Prometrium can be taken by mouth with or without food to avoid an upset stomach. The best way to use the drug is as recommended by your doctor.

There is also a patient information booklet that accompanies the medicine. Read this patient information booklet carefully.
