Descriptions


Estropipate is used to treat moderate to severe symptoms of menopause. It is also used to treat changes in and around the vagina (such as vaginal dryness, itching, and burning) caused by low estrogen levels or menopause. This medicine is also used to treat certain conditions in women before menopause if their ovaries do not make enough estrogens naturally, and prevent osteoporosis after menopause.

Estropipate is an estrogen hormone that works by preventing symptoms, such as feelings of warmth in the face, neck, and chest, or sudden strong feelings of heat and sweating (hot flashes) in women during menopause.

This medicine is available only with your doctor's prescription.

This product is available in the following dosage forms:

  • Tablet
