What is Domperidone?
Domperidone is a type of medicine called a dopamine antagonist, an anti-sickness medicine. The active ingredient domperidone speeds up the passage of food through the stomach into the intestine, which physically helps prevent vomiting and reduces nausea. Domperidone also prevents messages from being sent to the vomiting centre in the brain. This also helps reduce nausea and vomiting. Domperidone takes effect within 30 to 60 minutes and provides six to eight hours of relief. Domperidone is a prescription-only medicine.
What is it used for?
Dopamine antagonists are used to treat sickness (nausea) and vomiting due to many causes, including intestinal problems, migraine (severe headache), motion sickness or medical treatments such as chemotherapy and anaesthesia. Domperidone stops feelings of sickness and vomiting, whatever the cause may be.

Domperidone tablets should be swallowed whole with some liquid, preferably before meals. If used for migraine, take a Domperidone tablet and a painkiller as soon as you feel a migraine attack coming on. For more information, see the package leaflet.
