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.

This medication can cause birth defects in an unborn baby. Do not use if you are pregnant. Use an effective form of birth control, and tell your doctor if you become pregnant during treatment.

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.
