Additional Information

Atenolol is a beta blocker that is used to treat high blood pressure and other heart conditions. It works by blocking the action of certain natural chemicals in your body, such as epinephrine, that affect the heart and blood vessels. This results in a lowering of heart rate and blood pressure. Atenolol is available as a generic drug and as the brand-name drug Tenormin.

Atenolol belongs to a class of drugs called beta blockers. A class of drugs refers to medications that work similarly. They have a similar chemical structure and are often used to treat similar conditions. Atenolol is used to treat several different medical conditions. It primarily treats high blood pressure (hypertension) but can also be used for various other purposes. The drug works by lowering heart rate, blood pressure, and the workload of the heart. For high blood pressure this allows blood vessels in the brain, coronary arteries, and kidneys to work more efficiently. Lowering these functions helps reduce damage to your heart muscle and arteries and prevent strokes or kidney failure that can occur from hypertension.

Atenolol can also be used to treat other conditions such as: chest pain, irregular heartbeat, migraine headaches, and tremors. Atenolol may also be used for purposes not listed in this medication guide.

What is the difference between Atenolol and Metoprolol?

Atenolol and metoprolol are both beta blockers. Beta-blockers work by blocking the effects of adrenaline, which helps to lower blood pressure. Atenolol is a more selective beta blocker, meaning that it is targets the heart specifically, while metoprolol is a non-selective beta blocker that also affects other parts of the body. Because of this, atenolol is generally considered to be a safer and more effective option for treating hypertension.

What should you avoid when taking Atenolol?

You should avoid drinking alcohol while taking Atenolol, as it can increase the risk of low blood pressure and dizziness. You should also avoid becoming overheated or dehydrated, as this can also lead to low blood pressure. If you experience any of these side effects, stop taking Atenolol and seek medical help immediately.

What are the uses for Atenolol?

Atenolol is most commonly used to treat hypertension (high blood pressure). It is also sometimes used to prevent angina (chest pain), and to treat heart attack, tremors, congestive heart failure, and migraines. Atenolol may also be used off-label for other purposes, such as treatment of anxiety or withdrawal from alcohol.

Does Atenolol increase anxiety?

No, atenolol actually has anxiolytic (anti-anxiety) effects. However, some people may experience anxiety as a side effect of atenolol. If you experience anxiety while taking atenolol, stop taking the medication and seek medical help immediately.
