Domperidone is a medication used to relieve symptoms of nausea, vomiting, bloating, and discomfort related to slow stomach emptying. It works differently from many other anti-nausea medications and is commonly used for digestive complaints.
What Is Domperidone Used For?
- Nausea and vomiting
- Bloating, fullness, and upper abdominal discomfort after eating
- Gastroparesis-related symptoms (delayed stomach emptying)
- Nausea associated with certain other medications
In some countries, it is also used off-label under medical supervision to support breast milk production, though this use requires careful medical guidance due to safety considerations.
How Does Domperidone Work?
Domperidone blocks dopamine receptors in the gut, which helps increase the movement of food through the stomach and intestines. It also has an action in the brain’s vomiting center, unrelated to sedation, that helps reduce nausea without significant central nervous system side effects, since it does not readily cross into the brain.
General Dosage Information
- Common adult doses range from 10mg taken up to three times daily, generally before meals, for the shortest duration needed.
- Regulatory guidance in many countries limits total daily dose and duration of use due to heart rhythm safety concerns.
- It should always be taken as directed by a doctor, particularly regarding maximum duration of use.
Side Effects of Domperidone
- Dry mouth
