Combipatch

This medication is used to reduce menopause symptoms. It helps reduce episodes of flushing and sweating of the upper body and face, commonly called hot flashes. It also helps treat dryness, itching, and burning around the vagina. These symptoms occur when a woman's body no longer makes the usual amount of female hormone (estrogen) such as in women after menopause and in young women who have had their ovaries removed or who have a condition called primary ovarian failure. This medication is a combination of 2 female hormones: an estrogen (estradiol) and a progestin (norethindrone). A progestin is added to estrogen replacement therapy to reduce the risk of cancer of the uterus. A woman who has had her uterus removed does not need progestin and should not be treated with this combination medication. If you need treatment only for vaginal menopause symptoms (e.g., vaginal dryness), products applied directly inside the vagina should be considered before medications that are taken by mouth, absorbed through the skin, or injected.

If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.

Read the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. If you have any questions, consult your doctor or pharmacist. This medication is for use on the skin only. Follow the dosing schedule carefully. Dosage is based on your medical condition and response to therapy. Apply the patch to a clean, smooth, dry, non-irritated area of the lower abdomen. Do not place the patch on the breast. Avoid the waistline since tight clothing may rub the patch off. Press firmly on the patch for at least 10 seconds to make sure it stays in place. Replace the patch with a new one, usually twice weekly (every 3 or 4 days) or as directed by your doctor. Be sure to remove the old patch. Do not wear more than one patch at a time. To avoid skin irritation, change to a different area on the lower abdomen with each new patch and do not apply to the same area for at least a week. The patch should be worn continuously, even while bathing. Do not expose the patch to the sun for long periods. If a patch falls off, you may reapply it to a different area on the lower abdomen. If the patch does not stick any longer, use a new one and continue your usual dosing schedule. 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. Inform your doctor if your condition does not improve or if it worsens.

Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with your doctor or pharmacist first. This drug should not be used with the following medications because very serious interactions may occur: anastrozole, exemestane. If you are currently using any of these medications listed above, tell your doctor or pharmacist before starting estradiol/norethindrone. Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription products you may use, especially of: corticosteroids (e.g., prednisone), raloxifene, tamoxifen, warfarin, drugs affecting liver enzymes that remove estrogens from your body (such as azole antifungals including itraconazole, macrolide antibiotics including erythromycin, rifamycins including rifabutin, St. John's wort, certain anti-seizure medications including carbamazepine, phenobarbital, phenytoin). This product can affect the results of certain lab tests. Make sure laboratory personnel and all your doctors know you use this drug. This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.

Do not share this medication with others. Keep all medical and laboratory appointments. You should have a complete physical examination that includes blood pressure measurements and breast/pelvic examinations at regular intervals (e.g., once a year) or as directed by your doctor. Follow your doctor's instructions on how to examine your own breasts and report any lumps immediately. You should also be regularly screened for cervical cancer (e.g., Pap test) and have periodic mammograms as determined by your doctor. Consult your doctor for more details. Lifestyle changes that help promote healthy bones include increasing weight-bearing exercise, stopping smoking, limiting alcohol, and eating well-balanced meals that contain adequate calcium and vitamin D. Since you may also need to take calcium and vitamin D supplements and make lifestyle changes, consult your doctor for specific advice. Additional lifestyle changes (e.g., reducing stress, eating a low fat/low salt diet, losing weight if you are overweight) to control or prevent high blood pressure, high cholesterol, and diabetes help to prevent heart disease and strokes. Keep your mind active with mental exercises to help prevent dementia. Discuss with your doctor lifestyle changes that might benefit you. You can also manage hot flashes by keeping a cool body temperature (e.g., using a fan, drinking cool beverages, dressing lightly/in layers, avoiding hot/spicy foods). Limiting caffeine and alcohol, exercising regularly, and learning relaxation techniques may help reduce hot flashes. Vaginal lubricants can help lessen discomfort during intercourse.

If any of these persist or worsen, tell your doctor promptly. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional. Some estrogen products may also be used to prevent bone loss (osteoporosis) in people 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.

Rarely, very serious side effects have occurred when estrogen-only and combination hormone replacement therapies (estrogen and progestin HRT) are used after menopause. Discuss the risks and benefits of hormone treatment and your personal health history with your doctor. Combination HRT should not be used to prevent heart disease or dementia. Combination HRT can rarely cause heart disease (e.g., heart attacks), stroke, serious blood clots (pulmonary embolism and deep venous thrombosis), dementia, and breast cancer. The risk for stroke and breast cancer increases with age, especially for women older than 75. Estrogens may also increase the risk of cancer of the ovaries. 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 minimize 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 3-6 months) to see if you still need to use this medication. If you use this drug for an extended time, you should have a complete physical exam at regular intervals (e.g., once a year) or as directed by your doctor. See Notes section.
