Do not use Evamist® (estradiol transdermal spray) if you have undiagnosed abnormal genital bleeding; known, suspected, or history of cancer of the breast; known or suspected estrogen-dependent neoplasia; active DVT, PE, or history of these conditions; active arterial thromboembolic disease (for example, stroke and MI), or history of these conditions; known anaphylactic reaction or angioedema with Evamist; known liver impairment or disease; known protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders; or known or suspected pregnancy.
Estrogens increase the risk of gallbladder disease. Estrogens may lead to severe hypercalcemia in women with breast cancer and bone metastases. Retinal vascular thrombosis has been reported in women receiving estrogen. In women with preexisting hypertriglyceridemia, estrogen may be associated with elevations of plasma triglycerides leading to pancreatitis. Estrogens may be poorly metabolized in women with impaired liver function. Monitor thyroid function in women on thyroid replacement therapy. Estrogens may cause fluid retention. Estrogens should be used with caution in women with hypoparathyroidism as estrogen-induced hypocalcemia may occur. Exogenous estrogens may exacerbate symptoms of angioedema in women with hereditary angioedema and may cause an exacerbation of asthma, diabetes mellitus, epilepsy, migraine, porphyria, systemic lupus erythematosus, and hepatic hemangiomas in women with these conditions.
Avoid fire, flame, or smoking until Evamist® (estradiol transdermal spray) has dried. When sunscreen is applied approximately one hour after application of Evamist, estradiol absorption was decreased by 11 percent.
In a clinical trial, the most common adverse reactions that occurred with Evamist® (estradiol transdermal spray) were headache, breast tenderness and nipple pain, nausea, back pain, and nasopharyngitis.
