Duphaston 10mg tablets are a hormonal treatment commonly prescribed for menstrual disorders. The key active ingredient in Duphaston is dydrogesterone, a synthetic hormone that mimics the effects of the natural female hormone progesterone. Dydrogesterone helps regulate the menstrual cycle by supporting the growth of the uterine lining and preparing it for a potential pregnancy. This medication is often used to treat conditions such as irregular periods, painful periods, premenstrual syndrome (PMS), and endometriosis. Duphaston tablets are taken orally and are usually well-tolerated with minimal side effects.
