Key takeaways
Premarin (conjugated estrogens) and Evamist (estradiol) are both estrogen replacement therapies used to relieve menopausal symptoms like hot flashes and night sweats. However, they differ in their forms and applications. Premarin is an oral tablet that can also treat low estrogen levels due to other conditions and certain cancers in advanced stages, and helps prevent osteoporosis, while Evamist is a topical spray specifically for managing menopausal symptoms. Premarin can be taken daily or in cycles, whereas Evamist is applied once daily to the forearm. Premarin has a broader range of side effects, including weight gain and more severe risks like blood clots and certain cancers. Evamist, on the other hand, has milder side effects but can still pose serious risks, including early puberty in children if Evamist is transferred through skin contact as well as blood clots and certain cancers. Both medications require a prescription and are available only as brand-name products.
