Mechanism of action
Medroxyprogesterone is a synthetic progestogen that acts on the endometrium, transforming proliferative endometrium into secretory endometrium. It effectively inhibits the production of pituitary gonadotropins, which prevents follicular maturation and ovulation, thereby supporting management of specific reproductive healthcare needs.
Pregnancy and breastfeeding
Pregnancy: Do not use during pregnancy. Breastfeeding: Use with caution as it may be excreted in breast milk.
