What are Estraderm Patches?

Estraderm is a female hormone (estrogen). It is used by women to help reduce symptoms of menopause (such as hot flashes, vaginal dryness). These symptoms are caused by the body making less estrogen. If you are using this medication to treat symptoms only in and around the vagina, products applied directly inside the vagina should be considered before medications that are taken by mouth, absorbed through the skin, or injected. This medication may also be used by women who are not able to produce enough estrogen (for example, due to hypogonadism, primary ovarian failure). Certain estrogen products may also be used by women after menopause to prevent bone loss (osteoporosis). However, there are other medications (such as raloxifene, bisphosphonates including alendronate) that are also effective in preventing bone loss and may be safer. These medications should be considered for use before estrogen treatment.

Always read the patient information and instructions carefully before using this medication.

• Peel off the backing from the patch and apply the patch to a clean, dry area of the body as directed. This patch should only be applied to certain areas of the body. Different brands of patches are applied to different areas of the body.
• Press the patch firmly in place for about 10 seconds to make sure it stays on. Do not apply the patch on the breast or on oily, broken, or irritated skin. Avoid applying the patch to areas of the skin where it might be easily rubbed off (such as the waistline).
• The patch is usually replaced twice a week (every 3 to 4 days). Follow the dosing schedule carefully.
• When replacing your patch, make sure to apply the new patch to a different area. Wait at least 1 week before applying a patch to the same area. Fold the old patch in half with the sticky side together and throw away in the trash away from children and pets. Do not flush the patch down the toilet.
• If a patch falls off, reapply it to a different area. If the patch does not stick completely, then apply a new patch and wear it for the rest of the scheduled period. Do not wear 2 patches at the same time.
• Use this medication regularly to get the most benefit from it. To help you remember, change the patch on the same days each week. It may help to mark your calendar as a reminder.

Make sure to tell your doctor and pharmacist:

• If you have any drug allergies.
• Which other prescription and non-prescription medications you currently take.
• Your medical history, especially of: vaginal bleeding of unknown cause, certain cancers (such as breast cancer, cancer of the uterus/ovaries), blood clots, stroke, heart disease (such as heart attack), liver disease, kidney disease, family medical history (especially breast lumps, cancer, blood clots), family or personal history of a certain swelling disorder (angioedema), blood clotting disorders (such as protein C or protein S deficiency), high blood pressure, diabetes, high cholesterol/triglyceride levels, obesity, lupus, underactive thyroid (hypothyroidism), mineral imbalance (low or high level of calcium in the blood), a certain hormone problem (hypoparathyroidism), uterus problems (such as fibroids, endometriosis), gallbladder disease, asthma, seizures, migraine headaches, a certain blood disorder (porphyria), mental/mood disorders (such as dementia, depression).
• If you just had or will be having surgery, or if you will be confined to a chair or bed for a long time (such as a long plane flight). These conditions increase your risk of getting blood clots, especially if you are taking an estrogen product. You may need to stop this medication for a time or take special precautions.

Also be aware that:

• Do not smoke or use tobacco. Estrogens combined with smoking further increases your risk of stroke, blood clots, high blood pressure, and heart attack, especially in women older than 35.
