Coreg uses include the treatment of congestive heart failure and high blood pressure. The medication can also be administered immediately after a heart attack to help improve survival and decrease the chance of another heart attack. Off-label Coreg uses include migraine prevention, hyperthyroidism treatment, and the relief of alcohol withdrawal symptoms. It may also be used to slow down the progression of aortic dilation in children with Marfan syndrome.
Based on clinical studies, Coreg has been shown to significantly lower systolic and diastolic blood pressures. The higher the dose of Coreg, the greater the drop in blood pressure is expected to be. By lowering blood pressure, Coreg can also decrease the risks that often occur with long-term high blood pressure (see Effects of High Blood Pressure). Coreg does not, however, cure high blood pressure.
