Coreg (generic: carvedilol) is a prescription medication used to treat heart failure and hypertension (high blood pressure) in adults. Coreg belongs to a group of drugs called beta blockers. It works to decrease blood pressure, heart rate, and the workload of the heart by blocking beta receptors.
This medication comes in tablet form and is taken twice a day, with food and a full glass of water.
Common side effects of Coreg include hypotension (low blood pressure), weight increase, and fatigue. Coreg can cause dizziness. Do not drive a car or operate machinery until you know how Coreg affects you.
