Some common side effects associated with COREG include shortness of breath, a slow heartbeat, weight gain, fatigue, hypotension, dizziness, faintness, or runny nose/sore throat. People taking COREG 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. Beta-blockers may mask the symptoms of an overactive thyroid or low blood sugar, or may alter blood sugar levels. People with diabetes should report any changes in blood sugar levels to their physician. Contact lens wearers may produce fewer tears or have dry eyes.
As with any medicine, patients taking COREG should first tell their doctor what other medications they are taking. COREG should be taken with food.
