Key takeaways
Endometrin (progesterone) and Provera (medroxyprogesterone) are both used to address hormone-related issues, but they have different uses and forms. Endometrin is a vaginal insert or suppository used primarily in fertility treatments to help prepare the uterus for pregnancy, while Provera is an oral tablet used to regulate menstrual cycles and protect the uterus from damage in postmenopausal women taking estrogen replacement therapy. Endometrin must be used 2 to 3 times a day and can be expensive since it is only available as a brand medication. In contrast, Provera is taken once a day for a specific number of days each month and is available in a generic form. Endometrin can cause vaginal irritation and requires careful insertion, whereas Provera can cause side effects like spotting, breast tenderness, and nausea. Additionally, Provera has serious risks when taken with estrogen, such as increased risk of certain cancers, which are not associated with Endometrin.
