Monitor patient closely for loss of vision, proptosis, diplopia and thromboembolic disorders.

Description
FDA has not yet classified the drug into a specified pregnancy category.
Mode of Action
Medroxyprogesterone is a synthetic progestogen which converts the proliferative phase of the endometrium into secretory phase. It has some androgenic and anabolic activities but no oestrogenic effects. Parenteral use leads to inhibition of pituitary gonadotropins, thus preventing follicular maturation and ovulation.
Interaction
Aminoglutethimide and enzyme-inducing drugs (e.g. carbamazepine, griseofulvin, phenobarbital, rifampicin, phenytoin) may reduce plasma concentrations leading to reduced efficacy. Additional measures required when medroxyprogesterone is used for contraception during coadministration with these drugs.
Pregnancy Category Note
Pregnancy
Although therapy should not be used during pregnancy, there appears to be little or no increased risk of birth defects in women who have inadvertently been exposed to medroxyprogesterone acetate injections in early pregnancy; neonates exposed to medroxyprogesterone acetate in-utero and followed to adolescence showed no evidence of any adverse effects on their health including their physical, intellectual, sexual or social development
Lactation
Although the drug is detectable in the milk of mothers receiving therapy, milk composition, quality, and amount are not adversely affected; neonates and infants exposed to medroxyprogesterone acetate from breast milk have been studied for developmental and behavioral effects through puberty, and no adverse effects have been noted
