If you have milk on the third day after the miscarriage, you can wait for it to recede on its own, or you can apply milk-returning medication. Lactation after miscarriage usually disappears by itself within one week. When lactation persists or the amount of lactation is large, oral bromocriptine can be taken for 1~2 weeks, or ethinyl estradiol for 2~3 days, or intramuscular injection of estradiol benzoate until milk secretion stops, and a large dose of vitamin B6 has the effect of inhibiting milk secretion. Care should be taken to avoid stimulation of the breasts by squeezing, as emptying the milk may stimulate milk secretion and lead to increased milk production. Having milk is a normal phenomenon caused by the elevated level of hormones such as lactogen during pregnancy. If the amount of lactation is small, it can be stopped on its own, and if the amount of lactation is large, it can be treated with the appropriate medication. Lactation after abortion should be treated under the guidance of a physician to avoid the adverse consequences of self-medication.
