Dydrogesterone is a selective progesterone receptor agonist that acts similarly to natural progesterone. It converts the endometrium from a proliferative to a secretory phase, supports endometrial stability, and helps maintain pregnancy by promoting a favorable uterine environment.
Should not be used in patients with undiagnosed vaginal bleeding, liver disease, or known hypersensitivity to the drug. May cause side effects such as menstrual irregularities, headache, or breast tenderness. Use with caution during pregnancy (especially first trimester) and breastfeeding. Available by prescription only.
