Estradiol injection

What are estradiol injections?
ESTRADIOL CYPIONATE (DepGynogen®, Depo-Estradiol®, Depogen®, E-Cypionate®, Estragyn LA 5®, Estro-Cyp®) and ESTRADIOL VALERATE (Delestrogen®, Estro-L.A.®, Gynogen L.A.®, Menaval®, Valergen®) injections contain a estrogen female hormone. Estrogens are essential for maintaining normal female functions. Estrogens can help relieve symptoms of the menopause (hot flashes, night sweats, mood changes, and vaginal dryness and irritation). Estrogens can also help improve female functions in women with hormonal imbalance or problems with their ovaries. Estrogens can be given to patients with inoperable breast cancers (in men or women) or prostate cancer. Generic estradiol cypionate and estradiol valerate injections are available.

What should I watch for while taking estradiol injections?
Visit your prescriber or health care professional for regular checks on your progress. You should have a complete check-up every 6 months. You will also need a regular breast and pelvic exam and “Pap” smear while on estrogens therapy. You should also discuss the need for regular mammograms with your health care professional, and follow his or her guidelines for these tests. If you have any unusual bleeding contact your prescriber or health care professional for advice.

Estrogens can make your body retain fluid, making your fingers, hands, or ankles swell. Your blood pressure can go up. Contact your prescriber or health care professional if you feel you are retaining fluid.

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

Tobacco smoking increases the risk of getting a blood clot or having a stroke while you are taking estrogens, 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 prescriber or health care professional.

In women who still have their uterus, estrogens 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 estrogens 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 elective surgery, you may need to stop taking your estrogens one month beforehand. Consult your health care professional for advice prior to scheduling the surgery.

Where can I keep my medicine?
Keep out of the reach of children.

Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F); do not freeze. Throw away any unused medicine after the expiration date.
