Metoclopramide is commonly used to treat nausea and vomiting associated with conditions such as uremia, radiation sickness, cancer and the effects of chemotherapy, labor, infection, and emetogenic drugs. As a perioperative anti-emetic, the effective dose is usually 25 to 50 mg (compared to the usual 10 mg dose). It is also used in pregnancy as a second choice for treatment of hyperemesis gravidarum (severe nausea and vomiting of pregnancy). It is also used preventatively by some EMS providers when transporting people who are conscious and spinally immobilized. In migraine headaches, metoclopramide may be used in combination with paracetamol (acetaminophen) or in combination with aspirin. Evidence also supports its use for gastroparesis, a condition that causes the stomach to empty poorly, and as of 2010 it was the only drug approved by the FDA for that condition. It is also used in gastroesophageal reflux disease.
