This medicine can increase the risk of developing a condition (endometrial hyperplasia) that may lead to cancer of the lining of the uterus. Taking progestins, another hormone drug, with this medicine lowers the risk of developing this condition.

You should know, however, that taking estrogens with progestins may have additional health risks. You should discuss the use of estrogens and progestins with your health care professional to determine the benefits and risks for you.
If you are going to have surgery, you may need to stop taking this medicine. Consult your health care professional for advice before you schedule the surgery.
