Reglan is the brand-name version of metoclopramide. It belongs to a class of anti-nausea drugs called antiemetics. This medication typically treats heartburn, nausea, and vomiting.
Reglan also stimulates the stomach to help food pass through, emptying the digestive tract. People with diabetes may take Reglan when they have trouble emptying their stomachs, a condition called diabetic gastroparesis. Many people ask if Reglan helps with constipation, but it is usually not a recommended treatment.
