Dydrogesterone — Uses, Dosage, Side Effects & Safety

Drug class: Progestin (Synthetic Progesterone)

Overview

Dydrogesterone is a synthetic hormone similar to the naturally occurring female hormone progesterone. It is primarily used to treat conditions caused by progesterone deficiency, such as irregular menstrual cycles, painful periods, endometriosis, infertility due to luteal insufficiency, and to support early pregnancy in women with a history of recurrent miscarriage. Dydrogesterone works by mimicking the effects of natural progesterone in the body, helping to regulate the menstrual cycle and maintain the lining of the uterus. It is often prescribed as part of hormone replacement therapy (HRT) in combination with estrogen to reduce the risk of endometrial hyperplasia. Key points for patients: Dydrogesterone is generally well-tolerated, but should be taken exactly as prescribed. It does not have androgenic or estrogenic effects, making it suitable for women sensitive to these hormones. Always inform your healthcare provider about any other medications or health conditions before starting dydrogesterone.
