Atenolol is a medication that belongs to the beta-blocker class. It is used to treat high blood pressure, angina (chest pain), and certain types of heart rhythm disorders. It works by blocking the action of certain natural chemicals in the body, such as adrenaline, which can increase blood pressure and heart rate.
Atenolol is usually taken orally, once or twice daily, with or without food, as directed by your doctor or pharmacist. It is important to take atenolol regularly to get the most benefit from it.
Before taking atenolol, it is important to inform your doctor or pharmacist about any other medications you are taking, as it can interact with other drugs. It is also important to inform your doctor or pharmacist if you have any allergies or medical conditions, especially if you have a history of asthma or other breathing problems.
As with any medication, atenolol may cause side effects, such as fatigue, dizziness, and headache. These side effects are usually mild and go away after a few days of treatment. In rare cases, it can cause more serious side effects, such as low blood pressure, slow heart rate, or worsening of heart failure. If you experience any severe or persistent side effects, or if you have any concerns about the medication, consult your doctor or pharmacist immediately.
