What is Domperidone?
Domperidone is a prescription medication sometimes used in Canada to help increase milk production. Originally developed for digestive issues, it has the side effect of raising prolactin levels - a hormone that supports milk production.
Domperidone is most commonly used by breastfeeding parents with low milk supply, and it's also sometimes prescribed:
-
To induce lactation for adoptive or intended parents (in cases of surrogacy or adoption)
-
To relactate after weaning or after a break in breastfeeding
What the Research Says
Research shows that Domperidone may help induce or increase milk production for some parents. It is sometimes used when milk supply remains low even after factors such as poor milk removal or ineffective latch have been addressed.
These uses can be deeply meaningful. For many families - including adoptive, intended, or relactating parents - breastfeeding or chestfeeding is part of how they connect with and nurture their baby. Research supports Domperidone as one potential part of that journey.
It’s important to know that:
-
Domperidone should only be used under medical supervision.
-
It may not work for everyone.
-
It can have side effects, including heart rhythm changes or psychological impacts.
Because of these factors, it’s always best to begin with a full feeding assessment and to explore non-medication strategies first.
Using Domperidone Safely
If Domperidone is prescribed, it’s usually part of a broader plan that includes:
-
Optimizing milk removal: frequent feeding, effective latch, and pumping if needed
-
Monitoring milk production and baby’s growth
-
Regular follow-up with both your healthcare provider and lactation consultant
Never start, stop, or change your dose without professional guidance. Weaning off Domperidone too quickly can sometimes lead to a sudden drop in milk supply or psychiatric events. Gradual tapering is recommended, with ongoing support.

In Summary
Domperidone can be a helpful part of a comprehensive lactation plan for some families — but it’s not the first step. A full feeding assessment, practical support, and ongoing follow-up are key to protecting both milk supply and emotional well-being.
