Atenolol is a medication used to treat high blood pressure, angina (chest pain), and to prevent heart attacks. It belongs to a class of drugs known as beta blockers, which work by reducing the workload on the heart and decreasing the heart rate.
Atenolol is typically taken orally in tablet form. The dosage and duration of treatment will depend on the specific medical condition being treated and the patient's age and weight.
Side effects of atenolol may include dizziness, fatigue, and headache. Rare but serious side effects may include heart failure, bronchospasm (narrowing of the airways in the lungs), or an allergic reaction.
Atenolol may interact with other medications, so it's important to inform your healthcare provider of any other medications you are taking before starting treatment with atenolol. It should also be used with caution in patients with certain medical conditions, such as asthma or heart block.
