What should I watch for?
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. You should also discuss the need for regular mammograms with your health care professional, and follow his or her guidelines for these tests.
This medicine can make your body retain fluid, making your fingers, hands, or ankles swell. Your blood pressure can go up. Contact your doctor or health care professional if you feel you are retaining fluid.
If you have any reason to think you are pregnant, stop taking this medicine right away and contact your doctor or health care professional.
Smoking increases the risk of getting a blood clot or having a stroke while you are taking this medicine, 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 doctor or health care professional.
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. Therefore, if your uterus has not been removed (by a hysterectomy), your doctor 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 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.
You may bathe or participate in other activities while using this medicine. You do not need to remove the vaginal ring during sexual or other activities unless you are more comfortable doing so. Within the 90-day dosage period, you may remove the vaginal ring, rinse it with clean lukewarm (not hot or boiling) water, and re-insert the ring as needed.
