What is Menostar?

Estrogens increase the risk of endometrial cancer; monitor for abnormal vaginal bleeding. Estrogens with or without progestins should not be used for the prevention of cardiovascular disease or dementia. Increased risks of myocardial infarction, stroke, invasive breast cancer, pulmonary emboli, and deep vein thrombosis in postmenopausal women (50 to 79 years of age) have been reported. An increased risk of developing probable dementia in postmenopausal women 65 years of age or older has also been reported. Estrogens, with or without progestins, should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman .

Estrogen Alone TherapyThere is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Estrogen-alone therapy should not be used for the prevention of cardiovascular disease or dementia. The Women's Health Initiative (WHI) estrogen-alone substudy reported increased risks of stroke and deep vein thrombosis (DVT). The WHI Memory Study (WHIMS) estrogen-alone ancillary study of WHI reported increased risk of probable dementia in postmenopausal women 65 years or older.Estrogen Plus Progestin TherapyEstrogen plus progestin therapy should not be used for the prevention of cardiovascular disease or dementia. The WHI estrogen plus progestin substudy reported increased risks of stroke, DVT, pulmonary embolism (PE), and myocardial infarction (MI). The WHI estrogen plus progestin substudy reported increased risks of invasive breast cancer. The WHIMS estrogen plus progestin ancillary study of WHI reported an increased risk of probable dementia in postmenopausal women 65 years of age and older.Unintentional Secondary ExposureBreast budding, breast masses, and gynecomastia have been reported in children following unintentional secondary exposure to estradiol transdermal spray .

Estradiol transdermal gel, patch, and spray are used to treat moderate to severe hot flashes and other symptoms of menopause or low amounts of estrogen. It is also used to treat changes in and around the vagina (such as vaginal dryness, itching, and burning) caused by low estrogen levels or menopause. This medicine is also used to treat certain conditions in women before menopause if their ovaries do not make enough estrogens naturally, and prevent osteoporosis after menopause.

Estradiol is an estrogen hormone. The hormone from the patch, gel, and spray is absorbed through your skin into your body. It works by preventing symptoms, such as feelings of warmth in the face, neck, and chest, or sudden strong feelings of heat and sweating (hot flashes) in women during menopause.

This medicine is available only with your doctor's prescription.

It is very important that you use this medicine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. To do so may cause unwanted side effects.

This medicine is for use on the skin only. Do not get it in your eyes, nose, mouth, breast, or vagina. Do not use it on skin areas that have cuts, scrapes, or burns. If it does get on these areas, rinse it off right away with water.

• Carefully tear open the pouch when you are ready to put the patch on your skin. Do not cut it.
• Peel off the backing from the patch and apply the patch to a clean, dry, and hair-free area of the lower stomach or upper buttock area. This area must be free of powder, oil, or lotion for the patch to stick on to your skin.

• When replacing your patch, make sure to apply the new patch to a different area of your lower abdomen. Wait at least 1 week before applying a patch to the same area.
• When changing a patch, slowly peel it off from your skin. If you have any patch adhesive left on your skin, allow it to dry for 15 minutes and gently rub the sticky area with oil or lotion to remove it. It is best to change your patch on the same days of each week to help you remember.

After you prime the pump, do not press the pump more than 1 time each time you use it.
