What should I watch for while using this medicine?

Visit your doctor or health care professional for regular checks on your progress. You will need a regular breast and pelvic exam and Pap smear while on this medicine.

Smoking increases the risk of getting a blood clot or having a stroke while you are taking this medicine. You are strongly advised not to smoke.

This medicine does not prevent hot flashes. It may cause hot flashes in some patients.

This medicine can increase the risk of developing a condition (endometrial hyperplasia) that may lead to cancer of the lining of the uterus.

You should know, however, that taking a progestin may have additional health risks. You should discuss the use of these medicines 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.

If you have any reason to think you are pregnant; stop taking this medicine at once and contact your doctor or health care professional.
