Key takeaways
Medroxyprogesterone (Provera) and topical estradiol patch (Climara) are both medications used in hormone therapy, but they belong to different drug classes and have distinct uses. Medroxyprogesterone is a progestin, while estradiol is an estrogen replacement. Both medications can be used to manage symptoms related to menopause, but medroxyprogesterone is specifically used to regulate menstrual cycles and protect the uterus in postmenopausal women taking estrogen. Climara, on the other hand, is used to relieve menopause symptoms such as hot flashes and prevent bone loss. Medroxyprogesterone is taken orally, typically once a day for a set number of days each month, while Climara is applied to the skin once a week. Estradiol is available in a lower-cost generic form, whereas medroxyprogesterone is not. Common side effects of medroxyprogesterone include spotting and breast tenderness, while Climara can also cause breast pain and headaches. Both medications carry risks of blood clots and certain cancers.
