Learning About Pre-Op Beta-Blockers

Introduction

Beta-blockers help reduce the work the heart does. They do this by slowing your heartbeat and lowering your blood pressure. Some people take beta-blockers before surgery to lower the risk of heart problems after surgery. But beta-blockers are not right for everyone. Whether they are right for you depends on the type of surgery, your health, and your risk of heart problems. If you are having a heart surgery, you might take them to lower your risk of a heart rhythm problem. For other surgeries, you might take them to lower your risk of a heart attack and heart rhythm problems.

Do not take this medicine if you are allergic to any type of beta-blocker. Make sure to tell your doctor if you have chronic obstructive pulmonary disease (COPD), severe asthma, or frequent asthma attacks.
