Pharmacology Mechanism Of Action
Understanding how Provera works can alleviate concerns about its effectiveness and side effects. It functions by mimicking the effects of natural progesterone within the body. This hormone plays a crucial role in regulating menstrual cycles and managing various uterine conditions.

The onset of action for Provera varies but typically takes a few days for therapeutic effects to be noticed. It undergoes hepatic metabolism, where the liver converts the drug into active metabolites, aiding in its effectiveness. The elimination half-life of Provera is approximately 10 to 20 hours, indicating how long it remains active in the body before being excreted.
