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 can be particularly helpful for individuals experiencing digestive issues or side effects from other medications. In addition to its use for nausea, domperidone is sometimes prescribed to alleviate 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 potential side effects and interactions with other drugs.
