Background: The benefits of breast milk to the newborn infant are well established. The Canadian Paediatric Society recommends exclusive breastfeeding for the first 6 months of life for healthy, term infants. Mothers of premature newborns, however, may have difficulty providing an adequate supply of breast milk. Domperidone is officially used as a prokinetic agent. However, it is used widely around the world as a galactogogue. Despite its widespread use as a galactogogue, only a small number of investigators have studied domperidone for this indication.

Aims: The purpose of this study was to determine an optimal dosage of domperidone as a galactogogue.

Methods: Eligible subjects were randomized to receive domperidone 10 mg 3 times daily or domperidone 20 mg 3 times daily for 4 weeks. At week 5, the frequency was decreased to twice daily in both groups, and finally once daily for week 6.

Results: Over the entire first 4-week period, there was a significant increase in daily milk volumes within each group (P < .01). The between-group difference over this period, although not statistically significant, was clinically significant. Additionally, there was no significant within- or between-group difference during weeks 5 and 6.

Conclusion: A dose of domperidone of 20 mg, 3 times daily instead of 10 mg, 3 times daily was associated with a clinical, but not statistically significant, increase in milk production.
