Mechanism of action

DMPA acts as a long-acting reversible contraceptive by binding to progesterone receptors in the hypothalamus and pituitary gland, inhibiting the luteinizing hormone (LH) surge required for ovulation. It also alters the endometrium and increases cervical mucus viscosity, creating a hostile environment for sperm. The intramuscular or subcutaneous formulation provides contraceptive efficacy for approximately 12-13 weeks per injection.
