Domperidone is a medication primarily used to treat nausea and vomiting. It works by blocking dopamine receptors in the brain, which helps to increase the movement of food through the stomach and intestines. This action can alleviate symptoms associated with digestive issues and certain medical conditions. In addition to its use for nausea, Domperidone is sometimes prescribed to improve symptoms of gastroparesis, a condition where the stomach takes too long to empty its contents. It is important to use this medication under the guidance of a healthcare professional, as it may have side effects and interactions with other drugs.
