What should I watch for while using this medication?
Visit your care team for regular checks on your progress. You will need a regular breast and pelvic exam and Pap smear while on this medication. You should also discuss the need for regular mammograms with your care team, and follow their guidelines for these tests.
This medication can make your body retain fluid, making your fingers, hands, or ankles swell. Your blood pressure can go up. Contact your care team if you feel you are retaining fluid.
If you have any reason to think you are pregnant, stop taking this medication right away and contact your care team.
Smoking increases the risk of getting a blood clot or having a stroke while you are taking this medication, especially if you are more than 35 years old. You are strongly advised not to smoke.
If you wear contact lenses and notice visual changes, or if the lenses begin to feel uncomfortable, consult your eye care specialists.
This medication 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 medication, with this medication lowers the risk of developing this condition. Therefore, if your uterus has not been removed (by a hysterectomy), your care team may prescribe a progestin for you to take together with your estrogen. 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 care team to determine the benefits and risks for you.
If you are going to have surgery, you may need to stop taking this medication. Consult your care team for advice before you schedule the surgery.
