Why is Tenoretic prescribed?

Tenoretic (Atenolol and Chlorthalidone) is used to treat high blood pressure (hypertension). By lowering blood pressure, it helps reduce the risk of stroke, heart attack, and kidney problems.

What does it do?

Tenoretic is a combination medication that contains atenolol, a beta-blocker that slows the heart rate and reduces the force of heart contractions, and chlorthalidone, a thiazide-like diuretic that helps the body eliminate excess salt and water through urine. Working together, these components lower blood pressure by decreasing the heart’s workload and reducing fluid volume in the blood vessels.

How should I take it?

Take Tenoretic once daily, preferably in the morning to reduce nighttime urination. It can be taken with or without food, and it’s important to stay well-hydrated, unless otherwise directed by your doctor. Do not stop taking the medication abruptly, as this could worsen your condition.

What if I missed a dose?

If you miss a dose of Tenoretic, take it as soon as you remember. However, if your next scheduled dose is approaching, skip the missed dose and proceed with your usual dosing routine. Do not take extra or double doses to make up for the missed dose.

What are the special precautions before taking Tenoretic?

Do not take Tenoretic if you're allergic to Atenolol, Chlorthalidone, or any of the ingredients in the medication.

Disclose all your current or past medical conditions to your doctor, particularly if you have:

• Asthma or other lung conditions
• Heart problems
• Kidney disease
• Liver disease

• Gout or lupus
• Pheochromocytoma
• Psoriasis
• Peripheral vascular disease

Adults aged 65 and older may be more susceptible to certain side effects when taking this medication.

Is it safe to take it with another drug?

Tenoretic (Atenolol/Chlorthalidone) can interact with various medications, so it's important to check for potential interactions before taking it with another drug. Some interactions may increase side effects or reduce effectiveness.

Before taking Tenoretic, consult your doctor if you are using any of the following medications:

• Insulin
• Lithium
• Diuretics
• Ibuprofen

This is not a complete list of all the potential drug interactions, always consult your doctor or pharmacist before combining Tenoretic with other medications to ensure safety.

How should I store it?

Tenoretic should be stored in its original container at room temperature, ideally between 20°C and 25°C (68°F to 77°F). Keep the medication in a cool, dry place, away from direct sunlight, and ensure it is kept out of reach of children and pets.

What action should I take in case of overdose?

If you suspect an overdose of Tenoretic (Atenolol/Chlorthalidone), it's important to act quickly and seek immediate medical attention. Contact emergency services or go to the nearest hospital. Overdose symptoms may include severely slow or irregular heartbeat, fainting, difficulty breathing, or seizures.

Is it safe for pregnant or breastfeeding women?

Tenoretic (Atenolol/Chlorthalidone) is generally not considered safe during pregnancy or breastfeeding unless specifically prescribed by a healthcare provider after carefully weighing the potential risks and benefits. It is classified as FDA Pregnancy Category D, indicating there is positive evidence of fetal risk.

With regard to breastfeeding, both atenolol and chlorthalidone are excreted into breast milk. Atenolol may accumulate in the infant, particularly in newborns or preterm babies, while chlorthalidone may reduce milk production and could lead to electrolyte imbalances in the breastfed infant. If you are pregnant, planning to become pregnant, or breastfeeding, consult your healthcare provider for guidance on its use to ensure safety for both you and your baby.
