Can domperidone be used to increase breast milk production?
Domperidone has no official indication and is approved by ANVISA to increase breast milk production during lactation.
However, some studies [1, 2, 3] show that domperidone has a galactagogue effect, that is, it stimulates breast milk production by increasing blood levels of prolactin, which is the hormone responsible for stimulating milk production by the mammary glands.
Furthermore, these studies have shown that domperidone is safer in its use than other drugs that stimulate breast milk production, such as metoclopramide, for example, as it does not act on the brain, being better tolerated and causing less side effects.
Thus, despite not having an official indication in the drug leaflet, domperidone can be indicated by the obstetrician-gynecologist during lactation, to increase milk production, after a careful evaluation of the woman's he alth and the risks and benefits of its use. Thus, it is possible for the doctor to guide the safe dose and treatment time. See other ways to increase breast milk production.
How to take it
Domperidone should be taken orally, 15 to 30 minutes before meals and, if necessary, at bedtime.
