Table of contents:

Tenoretic is a prescription medication used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. It is a combination product that contains two active ingredients: atenolol and chlorthalidone.

Atenolol belongs to the class of medications called beta-blockers. It works by slowing down the heart and reducing the workload on the heart. Chlorthalidone belongs to the class of medications called diuretics (water pills). It works by getting rid of excess salt and water.

Uses and Dosage

Tenoretic is a tablet that should be taken orally with or without food as per the doctor's instructions, usually once a day. Take a Tenoretic tablet at least 4 hours before you go to bed to avoid getting up to urinate during the night. In case you have any dosing schedule-related questions, consult your doctor or pharmacist.

The recommended dosages of Tenoretic (Atenolol/Chlorthalidone) depend on each individual's health and medical condition. The typical starting dose of Tenoretic is one tablet of 50 mg atenolol/25 mg chlorthalidone daily, and the maximum recommended dose is one tablet of 100 mg atenolol/25 mg chlorthalidone daily. However, the actual dosage may vary based on factors such as age, weight, kidney function, and the severity of the condition being treated.

To derive maximum benefits from Tenoretic, take it regularly at the same time each day. You can use a reminder to remember to take it. In case you are taking medication to lower your cholesterol level, such as cholestyramine or colestipol, take it at least two hours before or four hours after taking Tenoretic.
