Metoclopramide is used to prevent nausea and vomiting from surgery or chemotherapy. It is also used by people with diabetes who have slow emptying of their stomachs (gastroparesis). Treating gastroparesis can decrease symptoms of nausea, vomiting, and stomach/abdominal fullness. Metoclopramide may also be used in certain procedures where stomach emptying is needed. Metoclopramide works by blocking a natural substance (dopamine) which can cause nausea and vomiting. It also speeds up stomach emptying and movement of the upper intestines. This drug is not recommended for use in children younger than 1 year due to an increased risk of serious side effects (such as muscle spasms/uncontrolled muscle movements). Ask the doctor or pharmacist for details.
