Atenolol is a medication used to treat high blood pressure (hypertension), angina, and some forms of cardiac arrhythmia. It belongs to a class of drugs known as beta-blockers, which work by blocking the action of certain hormones such as adrenaline on the heart and blood vessels. This results in a decrease in heart rate and blood pressure, which can help to reduce the workload on the heart and improve blood flow to the body's organs.
Atenolol is typically taken orally in the form of tablets, and the dosage and duration of treatment will depend on the individual's age, weight, and the condition being treated. It is important to take the medication as directed by a healthcare professional and to not suddenly stop taking it, as this can cause rebound high blood pressure or other adverse effects.
Common side effects of atenolol may include fatigue, dizziness, cold hands or feet, and gastrointestinal upset. In rare cases, atenolol may cause serious side effects such as difficulty breathing, chest pain, and irregular heartbeats. It is important to inform your healthcare provider of any other medications you are taking before starting treatment with atenolol, as they may interact with certain medications.
Atenolol is generally considered safe and effective when used as directed, but it may not be suitable for everyone. It is important to discuss the potential benefits and risks of atenolol with a healthcare professional before starting treatment.
