Atenolol (25mg) + Chlorthalidone (12.5mg)

Atenolol (25mg) + Chlorthalidone (12.5mg) — Uses and Benefits

This medicine is mainly used to treat high blood pressure (hypertension) in adults.

WHAT THIS MEDICINE IS USED FOR

• Controlling high blood pressure
• Reducing the risk of heart-related complications from long-term high blood pressure
• Sometimes used together with other blood pressure medicines for better control

HOW IT WORKS

• Atenolol blocks certain receptors in the heart, slowing the heart rate and reducing the force of contraction, which lowers blood pressure
• Chlorthalidone increases urine output by helping the kidneys remove excess salt and water, which further lowers blood pressure
• Together they give a more complete blood pressure control than either medicine alone

WHAT IT IS NOT USED FOR

• Not a painkiller or fever medicine
• Not used for immediate relief of a hypertensive emergency
• Not meant for occasional or as-needed use; it is for regular, long-term control of blood pressure
• Not a substitute for lifestyle changes like diet, exercise, and salt reduction
