Domperidone — Uses, Dosage, Side Effects & Safety

Drug class: Dopamine antagonist

Overview

Domperidone is a medication used to relieve symptoms of nausea and vomiting, as well as to help with stomach discomfort caused by slow gastric emptying (gastroparesis). It is also sometimes prescribed to improve symptoms of bloating, fullness, and heartburn, especially when these are related to delayed stomach emptying. Domperidone works by blocking dopamine receptors in the gut and the brain's chemoreceptor trigger zone, which helps speed up the movement of food through the stomach and reduces feelings of nausea. Key points for patients: Domperidone is generally well-tolerated when used at recommended doses and for short periods. It should be used only under medical supervision, as it may cause serious heart-related side effects in some people. Always follow your healthcare provider's instructions and report any unusual symptoms promptly.
