Uses:
This medication is a female estrogen hormone and is usually given to women who no longer produce the amount of estrogen they produced before menopause. It is used to prevent bone loss (osteoporosis) in women at high risk who cannot take non-estrogen drugs. There are several other medications (e.g., raloxifene, bisphosphonates such as alendronate) that are safe and effective to prevent or treat bone loss. These medicines should be considered for use before estrogen treatment.
Missed Dose
If you miss a dose, use it as soon as you remember. If a patch falls off, reapply the old patch to another area on your lower stomach. If the old patch does not stay on, throw it away, apply a new patch and wear it for the rest of the 7-day period. Then restart your usual dosing schedule. Do not double the dose to catch up.
How To Use
Read the Patient Information Leaflet available from your pharmacist. Consult your doctor or pharmacist if you have any questions. A patch is usually worn for 1 week and then replaced, or use as directed by your doctor. Follow the dosing schedule carefully. Do not open the sealed pouch container until ready for use. Open the pouch and remove the patch from the protective liner. Apply the patch to a clean, dry area on your lower stomach (below the belly button) and press firmly for about 10 seconds to make sure it stays on. Do not place the patch on your breast or on oily, red, or damaged skin. Avoid applying the patch to your waistline since it may rub off. Do not put the patch on areas where sitting may loosen it. After 1 week, remove the patch, fold it in half with the sticky sides together and throw it away. Do not flush it down the toilet. Apply a new patch to a different area to prevent skin irritation. If the area around the patch becomes red, itchy, or irritated, try a new site. If the irritation continues or becomes worse, notify your doctor promptly. If a patch falls off, reapply it or apply a new patch and wear it for the rest of the 7-day period. If you still have a womb (uterus), you should also take another hormone (progestin) for 2 weeks once or twice a year while using this medication. Consult your doctor or pharmacist for more details.

Warning
Estrogens given alone and with another hormone (progestin) for replacement therapy after menopause have sometimes caused rare but very serious side effects. Discuss the risks and benefits of hormone treatment and your personal health history with your doctor. Estrogens have been reported to increase the chance of cancer of the uterus (endometrial cancer). Taking a progestin with estrogen decreases this risk. Tell your doctor immediately if you have any unusual vaginal bleeding. Estrogens may also increase your risk of cancer of the ovaries, stroke, dementia, and serious blood clots in the legs. Estrogen given in combination with progestin can infrequently cause heart disease (e.g., heart attacks), stroke, serious blood clots (pulmonary embolism and deep venous thrombosis), dementia, and cancer of the breast. Some of these risks appear to depend on the length of time this drug is used and the amount of estrogen per dose. Therefore, this medication should be used for the shortest possible length of time at the lowest effective dose, so you can obtain the benefits and reduce the chance of serious side effects from long-term treatment. Discuss the details with your doctor and check with him/her regularly (e.g., every 3 to 6 months) to see if you still need to use this medication. Estrogen treatment alone does not appear to increase your risk of breast cancer when used for up to 7 years after menopause. However, talk to your doctor about the risks if you need to take estrogen for a longer period. Products that contain estrogen should not be used to prevent heart disease or dementia. If you use this drug for an extended period, you should have a complete physical exam at regular intervals (e.g., once a year) or as directed by your doctor. See Notes section.
