Domperidone for Breast Milk Supply

Introduction to Domperidone

Domperidone is effective and safe for increasing breast milk supply in lactating women with insufficient milk production, with low levels transferred to breast milk due to first-pass metabolism, and should be used after optimizing non-pharmacologic interventions, as recommended by the American College of Obstetricians and Gynecologists 1, 2

Before prescribing domperidone, ensure that non-pharmacologic interventions such as frequent feeding or pumping, proper latch technique verification, adequate maternal hydration and nutrition, and skin-to-skin contact have been maximized, as suggested by the American College of Obstetricians and Gynecologists 2, 3
Rule out underlying conditions causing low supply, including retained placental fragments, thyroid dysfunction, and insufficient glandular tissue, before initiating domperidone therapy, as recommended by the American College of Obstetricians and Gynecologists 2, 3

Domperidone levels in breast milk are low due to extensive first-pass hepatic and intestinal metabolism when taken orally, making it compatible with breastfeeding, as noted by the American College of Obstetricians and Gynecologists 1, 3, 4
The American College of Obstetricians and Gynecologists identifies domperidone as a primary galactagogue medication, though it is not FDA-approved for this indication in the United States 2
The standard dose of domperidone is 10 mg orally three times daily for 14-28 days, and it is essential to ensure access to a breast pump if any delay in infant feeding occurs, as recommended by the American College of Obstetricians and Gynecologists 1, 2

The milk:plasma ratio of domperidone is 0.25, indicating minimal transfer to breast milk, with a relative infant dose of 0.01-0.35%, which is well below the 10% safety threshold, and 93% plasma protein binding, limiting free drug available for milk transfer, according to the Anaesthesia journal 5, 6, 7

Domperidone has favorable pharmacokinetic properties for breastfeeding, with low levels in breast milk due to extensive first-pass hepatic and intestinal metabolism when taken orally, although the exact levels are not specified in the provided references 5, 6, 7
