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 may be pregnant, stop taking this medication right away and contact your care team. Talk to your care team if you use tobacco products. Changes to your treatment plan may be needed. Tobacco increases the risk of getting a blood clot or having a stroke while you are taking this medication. This risk is higher if you are 35 years or older. 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 elective surgery, tell your care team you are taking this medication. You may need to stop taking this medication before the surgery.

What are the most serious risks of this medication?

Do not use this medicine to prevent heart disease. Using estrogens with or without progestins may increase your chances of getting heart attacks, strokes, or blood clots. Estrogens with progestins may increase your chances of getting breast cancer. Talk to your healthcare provider before taking this medicine if you have ever had cancer. Call your healthcare provider right away if you get new breast lumps. Estrogens with or without progestins may increase your chance of getting dementia based on a study of women 65 years of age or older. If you have a uterus, using estrogens alone (without progestins) may increase your chance of uterine cancer (cancer of the womb).
