Adults and children with nausea and vomiting can be treated with Motilium 1 mg/mL Oral Suspension. Domperidone, an ingredient in it, helps the stomach empty more rapidly, which lessens nausea and stops vomiting. By accelerating stomach emptying, this oral solution effectively reduces nausea and vomiting symptoms. However, people who are allergic to domperidone or any other component of the medication shouldn't take it.
