What it is used for
- Nausea and vomiting
- Feeling of fullness, bloating, or stomach discomfort linked to slow stomach emptying
How it works
Domperidone blocks dopamine signals that cause nausea and helps the stomach contract and empty more effectively, easing nausea, vomiting, and a sense of fullness.
How it is taken
Comes as tablets and oral liquid. It is taken by mouth, usually before meals. Because it can affect heart rhythm, it is prescribed at the lowest effective amount for the shortest time; take it exactly as your clinician directs.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
Common side effects
- Dry mouth
- Headache
- Mild stomach cramps
Serious effects — get help

If a reaction is severe — for example trouble breathing, swelling of the face or throat, or collapse — go to the nearest emergency room now or call your local emergency number. Do not wait for an online consultation.
