Chlormadinone Acetate

Very Low Risk for breastfeeding


Safe. Compatible.
Not risky for breastfeeding or infant.

Synthetic progestin-related drug similar to the progesterone used for treatment of uterine bleeding, dysmenorrhea, infertility and occasionally for prostate problems.
It has been used as a birth control medication, as single component or in combination with estrogen (e.g. mestranol + chlormadinone).

No changes in prolactin were observed on plasma levels or milk production in women treated with chlormadinone.

During lactation progestin-only drugs are preferred or in combination with estrogen for birth control, but whatever, the ones with the lower doses of estrogen should be used.
For the first 6 weeks postpartum, non-hormonal methods are of choise.
