Uses For Tenoretic 100

Atenolol and chlorthalidone combination is used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled .

Atenolol is a beta-blocker. It works by affecting the response to some nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart .

Chlorthalidone is a diuretic (water pill). It reduces the amount of water in the body by increasing the flow of urine, which helps to lower blood pressure .

This medicine is available only with your doctor's prescription .

Before Using Tenoretic 100

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of atenolol and chlorthalidone combination in the pediatric population. Safety and efficacy have not been established .

Geriatric

Appropriate studies performed to date have not demonstrated geriatrics-specific problems that would limit the usefulness of atenolol and chlorthalidone combination in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require an adjustment of dosage in patients receiving atenolol and chlorthalidone combination .
