What is Progesterone? Full information, usage, benefits and side effects


Progesterone (P4) is an endogenous steroid and progestin sex hormone involved in the menstrual cycle, pregnancy and embryogenesis in humans and other species. Progesterone belongs to a class of drugs called progestins (female hormones). It works as part of hormone replacement therapy by reducing the amount of estrogen in the uterus. It works to induce menstruation by replacing the natural progesterone that some women lack.


Progesterone is used to induce menstrual bleeding in women who have not yet reached menopause but are not menstruating due to a lack of progesterone in their bodies.
Progesterone is used as part of hormone replacement therapy for women who have passed menopause (a life change) and have not had a hysterectomy (surgery to remove the uterus).

Progesterone should not be used to prevent heart disease or dementia.


Use progesterone as prescribed. Follow all directions on the prescription label. Do not use this medicine in large or small amounts or for longer than recommended.

Please read all patient information, medication guides, and instructions for use provided. If you have any questions, ask your doctor or pharmacist. Take the capsule with a glass of water. It may cause dizziness and drowsiness, so it is recommended to take it at night.

Apply progesterone cream to your skin as directed by your doctor.
