Sandoz Estradiol Derm

A new patch should be applied to your skin on the same days twice a week (i.e., the patch should be changed once every 3 to 4 days). Depending on the individual, your doctor may advise you to use the patches continuously or in a cyclic schedule (approximately 3 weeks of treatment with patches followed by approximately one week without patch use). Talk to your doctor if you are not sure whether you are using estradiol patch continuously or with a patch-free period.

Women who have not had a hysterectomy (removal of their uterus) must also take a progestin while they are taking this medication to prevent adverse effects associated with the use of estrogen.

The patch is often applied to the buttocks, lower abdomen, or hip. Many women have found that less skin irritation occurs when the patch is applied to the buttocks. Talk to your doctor or pharmacist about the most appropriate site to apply the patch. Do not apply the patch to your breasts. Do not apply patches to the same site on the skin twice in a row.

To apply the patch:

1. Choose a clean and dry area of intact skin that is not oily, damaged, irritated, or exposed to the sun. To avoid irritation, do not apply to the same site on the skin 2 times in a row.
2. Tear open the pouch containing the patch rather than using scissors – if you accidentally cut the patch, it will be useless.
3. Remove the protective layer. Apply the patch to the selected area immediately. Avoid touching the adhesive.
4. Use your fingers to hold the patch in place for about 10 seconds and make sure that the patch is affixed to your skin, especially around its edges.

When changing the patch, remove the old one carefully, fold it in half so that the adhesive sides stick together, and throw it away or bring it to the pharmacy for proper disposal. Keep it out of the reach of children or pets. If adhesive remains on your skin, rub it off gently.

Bathing, showering, swimming, or other contact with water does not affect the patch. However, hot water or steam may cause the patch to loosen. If your patch falls off, try to reapply it. If that doesn't work, apply a new patch.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.

It is important to use Sandoz Estradiol Derm (Estradiol-transdermal) exactly as prescribed by your doctor. If you forget to apply or change your patch, change it as soon as you remember. If it is close to the day when you normally change your patch, still apply it but change the patch again on your usual day and continue on with your regular schedule. Do not wear 2 patches at once. If you are not sure what to do after forgetting to apply or change the patch, contact your doctor or pharmacist for advice.

Note the following important information about estrogen replacement therapy:

The Women's Health Initiative (WHI) study results indicated an increased risk of heart attack, stroke, breast cancer, blood clots in the lungs, and blood clots in the leg veins in postmenopausal women during 5 years of treatment with 0.625 mg conjugated equine estrogens and 2.5 mg medroxyprogesterone compared to women receiving sugar tablets. Other combinations of estrogen and progestins were not studied. However, until additional data are available, the risks should be assumed to be similar for other hormone replacement products. Therefore,

• estrogens with or without progestins should be used at the lowest dose that relieves your menopausal symptoms for the shortest time period possible, as directed by your doctor
• estrogens with or without progestins should not be used to prevent heart disease, heart attacks, or strokes

Allergy: Contact allergy, such as itching and redness, is known to occur with the application of estrogen to the skin. Although this allergy is extremely rare, people who develop skin reactions or contact sensitization to any component of the medication are at risk of developing a severe allergic reaction with continued use. If you have a skin reaction to the patch, contact your doctor for advice.

Blood clotting disorders: Estrogens with or without progestins are associated with an increased risk of blood clots in the lungs (pulmonary Embolism) and legs (deep vein thrombosis). If you have or have had a heart attack, a stroke, heart disease, a blood clot in your leg, or have medical conditions that increase your risk of blood clots, you should not use this medication.

The risk of developing blood clots also increases with age, a personal or family history of blood clots, smoking, and Obesity. It is also increased if you are immobilized for prolonged periods and with major surgery.

If possible, Sandoz Estradiol Derm (Estradiol-transdermal) should be stopped 4 weeks before major surgery. Talk about the risk of blood clots with your doctor.

Blood pressure: Women may experience increased blood pressure when using estrogen replacement therapy. Your doctor should monitor your blood pressure or advise you on how often you should measure your blood pressure if you are using estrogen, especially if high doses are used. Regular checkups by your doctor are recommended. If you have high blood pressure, discuss with your doctor how Sandoz Estradiol Derm (Estradiol-transdermal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Sandoz Estradiol Derm (Estradiol-transdermal), and whether any special monitoring is needed.

Bone disease: If you have bone disease due to cancer or a metabolic condition causing too much calcium in your body, discuss with your doctor how Sandoz Estradiol Derm (Estradiol-transdermal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Sandoz Estradiol Derm (Estradiol-transdermal), and whether any special monitoring is needed.

Breast and Ovarian Cancer: Studies show there is an increased risk of breast and ovarian cancer with long-term use of estrogen replacement therapy. Women with a history of breast cancer should not use estrogens. Women who have breast nodules, fibrocystic disease, abnormal mammograms, or a strong family history of breast cancer should be closely monitored by their doctor.

Women taking estrogens should have regular breast examinations and should be instructed in breast self-examination. The estradiol patch must not be applied to the breasts, as it may have harmful effects on the breast tissue.

Dementia: Women over the age of 65 receiving combined hormone replacement therapy (estrogen and progestin) may be at increased risk of developing dementia (loss of memory and intellectual function). If you are over 65, talk to your doctor about whether you should be tested for dementia.

Diabetes: Estrogens can cause changes in blood glucose control for people who have diabetes or have risk factors for developing diabetes. If you have diabetes or are at risk for developing diabetes (e.g., have a family history of diabetes, have high blood pressure or High Cholesterol, or are obese), discuss with your doctor how Sandoz Estradiol Derm (Estradiol-transdermal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Sandoz Estradiol Derm (Estradiol-transdermal), and whether any special monitoring is needed.

People who have diabetes (or a predisposition to diabetes) should monitor their blood glucose levels closely to detect changes in blood glucose.

Endometrial cancer: There is evidence from several studies that estrogen replacement therapy can increase the risk of cancer of the endometrium (lining of the uterus). Taking a progestin at the right time along with the estrogen reduces this risk of endometrial cancer to the same level as that of a woman who does not take estrogen. For this reason, all women who have not had their uterus removed should also take a progestin if they are using estrogens.

If you develop any abnormal vaginal bleeding while using Sandoz Estradiol Derm (Estradiol-transdermal), contact your doctor. If you have or have had endometrial cancer, you should not use Sandoz Estradiol Derm (Estradiol-transdermal).
