Mechanism & Pharmacology

Provera, also known as medroxyprogesterone acetate, acts primarily as a progestogen. By mimicking natural progesterone, it plays a key role in regulating the menstrual cycle and maintaining hormonal balance in individuals with a uterus. This medication helps prepare the uterine lining for potential pregnancy and prevent overgrowth, contributing to the management of abnormal uterine bleeding. Hormonal therapies like Provera are essential for addressing conditions such as secondary amenorrhea and endometrial hyperplasia, restoring regularity to menstrual cycles.

Clinical Terms

According to Health Canada’s approved monograph, Provera is indicated for a variety of clinical conditions including:

• Secondary amenorrhea: a condition where menstruation stops in women who previously had normal periods.
• Abnormal uterine bleeding: irregular bleeding not attributed to normal menstruation.
• Endometrial hyperplasia: a thickening of the uterine lining, which can lead to cancer if untreated.

The clinical context of Provera underscores its significance in hormonal therapy within gynecology.

Indications & Off-Label Uses in Canada

Health Canada has approved several indications for Provera, designated by its Drug Identification Number (DIN). Generally, it is prescribed for managing secondary amenorrhea and irregular menstruation. The typical dosing for these conditions ranges from 5 mg to 10 mg, taken daily for a specified duration according to the patient’s needs.

Common Off-Label Practices

Canadian physicians sometimes prescribe Provera for off-label uses such as:

• Treating chronic menstrual disorders that do not fit typical categories.
