Uses of Dydrogesterone:
Dydrogesterone is a progestogen hormone. Dydrogesterone is a potent, orally active progestogen indicated in a wide variety of gynaecological conditions. The therapeutic use of dydrogesterone is closely related to its physiological action on the neuro-endocrine control of ovarian function, as well as on the endometrium. Dydrogesterone has proven effective in the following conditions: menstrual disorders; infertility; threatened and habitual abortion; endometriosis; premenstrual syndrome. Dydrogesterone has also been registered as hormone replacement therapy (HRT) to counteract the negative effects of unopposed oestrogen on the endometrium. Dydrogesterone is safe and well-tolerated. The incidence of side-effects is remarkably low.
