According to InhousePharmacy.biz, Duphaston (dydrogesterone) is prescribed during early pregnancy to help maintain the uterine lining, also known as endometrium, preventing it from growing and causing it to secrete hormones and other proteins necessary for a healthy pregnancy. It is a synthetic hormone that mimics the effects of progesterone but is more easily absorbed by the gastrointestinal system.
Side effects include nausea, bloating, breast pain, spotting, dizziness, weight gain and migraines, according to InhousePharmacy.biz. However, distinguishing it from other sources of synthetic progesterone, Duphaston does not interfere with the effects of oestrogen, allowing the body to prevent bone loss and regulate cholesterol. Because it does not contain testosterone, Duphaston does not cause any androgenic side effects like hirsutism or acne.
InhousePharmacy.biz states that Duphaston is also commonly used to treat menstrual disorders, especially endometriosis. Duphaston prevents the endometrium from growing in all of its locations, reducing the likelihood of common symptoms like pain and spotting recurring. Duphaston also regulates and normalizes irregular menstrual cycles caused by an imbalance of hormones, making it an effective treatment for both amenorrhoea and spotting.
Duphaston can also be a part of transgender treatment, according to InhousePharmacy.biz, used during the transition from male to female. Drydogesterone in conjunction with oestrogen stimulates the development of female sexual characteristics.
