Beta Blockers for Heart Problems

Path to improved health

You should take beta blockers exactly as your doctor tells you. Beta blockers often are taken 1 to 2 times a day. Try to take the medicine at the same time each day. Do not stop taking beta blockers without talking to your doctor first. If you missed a dose and realize it a few hours later, take the medicine right away. If it has been more than 4 to 6 hours, do not take the dose you missed. Instead, wait to take the next scheduled dose. Never take a double dose to catch up.

People who have certain health conditions need to be careful taking beta blockers. If you have diabetes, the medicine can hide warning signs of low blood sugar. For example, your heart rate may not increase normally in response to a low blood sugar level. You will need to check your blood sugar levels carefully when taking a beta blocker. Talk to your doctor if you often have low blood sugar. He or she may want to change the dosage of your diabetes medicine.

Beta blockers can be a problem for people who have asthma. They can cause asthma attacks. Work with your doctor to monitor your asthma and prevent attacks.

People who have a chronic lung disease, such as bronchitis, emphysema, or both diseases together, known as chronic obstructive pulmonary disease (COPD), can take beta blockers. However, you should call your doctor right away if you start having breathing problems.

Beta blockers may interact with other medicines. This includes over-the-counter medicines and prescriptions. The interaction can cause severe health problems. Tell your doctor about all medicines that you take. Check with your doctor before starting any new medicine.
