Some common side effects associated with COREG CR include shortness of breath, a slow heartbeat, weight gain, fatigue, hypotension, dizziness, faintness, or runny nose/sore throat. People taking COREG CR who have any of these symptoms should call their doctor.
Additionally, if patients experience fatigue or dizziness, they should sit or lie down and avoid driving or hazardous tasks.
