Prometrium is a synthetic form of progesterone, a hormone produced naturally by the body. It contains the hormone progesterone. Prometrium works by replacing the progesterone that the body no longer produces after menopause.

Prometrium is used to treat a variety of conditions, including amenorrhea, endometriosis, infertility, and abnormal bleeding. It is also used in combination with other treatments for menopausal symptoms such as hot flashes and night sweats. It can also be used as hormone replacement therapy (HRT) in women. Prometrium is available as capsules containing micronized progesterone for oral administration.

Uses and Dosage

Prometrium is available in the form of a soft gel capsule that is taken orally once a day at bedtime, as prescribed by the doctor. If swallowing the capsule is difficult, it can be taken with a full glass of water while standing up. Follow the dosing schedule carefully, and the dosage is determined by the patient's medical condition and response to therapy.
