Domperidone is often used to relieve nausea and vomiting, while Rabeprazole helps reduce stomach acid, treating conditions like GERD (gastroesophageal reflux disease). When combined, they can help manage symptoms related to digestive issues. It's important to follow your healthcare provider's dosing instructions, as Domperidone can have side effects like dry mouth or dizziness. Always discuss potential interactions and side effects with your doctor.
