- Abdominal distension
- Upper abdominal pain

Domperidone for lactation
Domperidone has no official indication approved by the FDA for increasing breast milk production during lactation.
However, some studies have shown that domperidone has a galactagogue effect, meaning it stimulates breast milk production by increasing blood levels of prolactin. This hormone is responsible for stimulating milk production in the mammary glands.
In addition, these studies have shown that domperidone is safer to use than other drugs that stimulate breast milk production, such as metoclopramide, for example, because it doesn't act on the brain, is better tolerated and causes fewer side effects.
Although it does not having an official indication for breastfeeding, domperidone can be prescribed for off-label use by the obstetrician-gynecologist during lactation to increase milk production. The doctor should first first assess the woman's health and the risks and benefits of its use before prescribing to ensure safety and outline a treatment duration.

Domperidone for diarrhea
Domperidone is not indicated for the treatment of diarrhea, as its main effect is to delay gastric emptying in conditions like GERD, indigestion, heartburn or abdominal distension.
It is especially worth noting that one of the side effects of this medication is diarrhea.
However, one study showed that domperidone can be used to avoid hospitalization in cases of acute diarrhea by reducing the frequency of intense vomiting. However, no changes were recorded in relation to diarrhea, so more studies are needed to verify this effect. Learn more about the diarrhea medicine you can take instead to treat loose stools.
