Atenolol is a beta-blocker medication used primarily for managing high blood pressure, angina (chest pain), and for improving survival after a heart attack. It works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart.

How is this medication used?

Atenolol is taken by mouth with or without food, usually once or twice a day as directed by your doctor. Dosage is based on your medical condition and response to treatment. For the treatment of high blood pressure, it may take 1-2 weeks before you get the full benefit of this drug. It's important to continue taking this medication even if you feel well.

What are the possible side effects?

Common side effects of atenolol include dizziness, lightheadedness, fatigue, and nausea. If any of these effects persist or worsen, tell your doctor promptly. More serious side effects may include very slow heartbeat, severe dizziness, fainting, blue fingers/toes, trouble breathing, or new or worsening symptoms of heart failure.

What are the potential interactions?

Atenolol can interact with other medications, vitamins, or herbs you may be taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well. To avoid interactions, your doctor should manage all of your medications carefully. Be sure to inform them of all medications you use, including over-the-counter drugs and supplements. Notable interactions include other blood pressure medications, drugs that lower heart rate, and certain antidepressants.
