What is Menostar?

Menostar is a skin patch that contains estradiol, a form of estrogen. Estradiol is a female sex hormone the regulates many processes in the body.

Menostar skin patches are used to prevent postmenopausal osteoporosis. Menostar skin patches release estradiol slowly, and it is absorbed through your skin. They are used to provide the female hormone when the body no longer produces enough.

Menostar may also be used for other purposes not listed in this medication guide.

Important information about Menostar

Do not use Menostar if you have any of the following conditions: a history of stroke or blood clot, circulation problems, a bleeding disorder, a hormone-related cancer such as breast or uterine cancer, or abnormal vaginal bleeding. Menostar can cause birth defects in an unborn baby. Do not use if you are pregnant. Use an effective form of birth control, and tell your doctor if you become pregnant during treatment.

Estradiol increases your risk of developing endometrial hyperplasia, a condition that may lead to cancer of the uterus. Taking progestins while using estradiol may lower this risk. If your uterus has not been removed, your doctor may prescribe a progestin for you to take while you are using Menostar.

Long-term Menostar treatment may increase your risk of breast cancer, heart attack, or stroke. Talk with your doctor about your individual risks before using Menostar long-term. Your doctor should check your progress on a regular basis (every 3 to 6 months) to determine whether you should continue this treatment.

Have regular physical exams and self-examine your breasts for lumps on a monthly basis while using Menostar.

The Menostar transdermal patch may burn your skin if you wear the patch during an MRI (magnetic resonance imaging). Remove the patch before undergoing such a test.
