What the medication is used for

JAMP-DOMPERIDONE is used to treat symptoms of slowed stomach emptying seen in people with some gastrointestinal disorders (e.g. gastritis- inflammation of the GI tract). JAMP-DOMPERIDONE is also used to reduce symptoms such as nausea and vomiting caused by some drugs used to treat Parkinson’s disease.
