What is the most important information I should know about estropipate (Ogen)?

Do not use this medication if you have any of the following conditions: a history of stroke or blood clot, circulation problems, a hormone-related cancer such as breast or uterine cancer, or abnormal vaginal bleeding.

Estropipate increases your risk of developing endometrial hyperplasia, a condition that may lead to cancer of the uterus. Taking progestins while using estropipate may lower this risk. If your uterus has not been removed, your doctor may prescribe a progestin for you to take while you are using estropipate.

Long-term estropipate treatment may increase your risk of breast cancer, heart attack, or stroke. Talk with your doctor about your individual risks before using estropipate long-term. Your doctor should check your progress on a regular basis (every 3 to 6 months) to determine whether you should continue this treatment.

Have regular physical exams and self-examine your breasts for lumps on a monthly basis while using estropipate.
