If progesterone is used to treat functional uterine bleeding, it can gradually stop bleeding after 3 to 5 days of medication, but it is necessary to continue taking medication for about three weeks. Progesterone is a common drug with multiple therapeutic effects, including regulating female menstruation and protecting pregnancy. It can be used to treat threatened abortion.

How Many Days Does It Take for Progesterone to Stop Bleeding?

Progesterone is used to treat functional uterine bleeding during menopause. After taking the drug for 3 to 5 days, you need to continue taking it for 21 days, and menstruation will resume 3 to 7 days after stopping the medication. When taking progesterone orally to treat functional uterine bleeding, it is important to note that you should not miss any doses, as missing a dose can lead to rebleeding. It is best to take it at a fixed time and not stop the medication without authorization, as stopping the medication can lead to withdrawal bleeding, which is difficult to stop again. If bleeding does not stop after taking the medication for 5 days, a diagnostic curettage is recommended.
