Key takeaways
Medroxyprogesterone (Provera) and estradiol (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. Estradiol, on the other hand, is used to relieve menopause symptoms like hot flashes and prevent bone loss. Medroxyprogesterone is taken orally, typically once a day for 5 to 14 days per month, while estradiol is applied as a transdermal patch once a week. Both medications are available as a lower-cost generic. Common side effects of medroxyprogesterone include spotting and breast tenderness, while estradiol can cause breast pain and headaches. Both medications carry risks of blood clots and certain cancers, especially when used together or with other hormones.
