Progesterone — Uses, Dosage, Side Effects & Safety

Drug class: Progestin (Hormone Replacement Therapy)

Overview

Progesterone is a naturally occurring female hormone that plays a key role in the menstrual cycle and in maintaining pregnancy. It is used as a medication to treat conditions such as irregular menstrual periods, abnormal uterine bleeding, infertility, and as part of hormone replacement therapy (HRT) for menopausal symptoms. Progesterone is also used to support early pregnancy in women undergoing assisted reproductive technology (ART) treatments. This medication works by supplementing or replacing the body's natural progesterone, helping to regulate the growth and shedding of the uterine lining. For women who do not produce enough progesterone naturally, this hormone can help restore hormonal balance and reduce symptoms. Key points: Progesterone should be taken exactly as prescribed. It is important to follow your healthcare provider's instructions and report any unusual symptoms, especially if you have a history of blood clots, liver disease, or breast cancer.
