PHONETIC PRONUNCIATION: (a-TEN-oh-lol/klor-THAL-i-done)
COMMON BRAND NAME(S): Tenoretic
GENERIC NAME(S): atenolol/chlorthalidone
Uses
USES: This medication is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains 2 medications: atenolol and chlorthalidone. Atenolol belongs to a class of drugs known as beta blockers. It works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart. Chlorthalidone is a "water pill" (diuretic) and causes your body to get rid of extra salt and water. This effect may increase the amount of urine you make when you first start the medication. It also helps to relax the blood vessels so that blood can flow more easily. These medications are used together when 1 drug alone is not controlling your blood pressure. Your doctor may direct you to start taking the individual medications first, and then switch you over to this combination product if this is the best dose combination for you.
How to use ATENOLOL/CHLORTHALIDONE - ORAL

If you take this drug too close to bedtime, you may need to wake up to urinate. Therefore, it is best to take this medication at least 4 hours before your bedtime. Consult your doctor or pharmacist if you have questions about your dosing schedule. Apple juice and orange juice may prevent your body from fully absorbing atenolol. It is best to avoid drinking apple/orange juice within 4 hours of taking this medication, unless your doctor or pharmacist tells you otherwise. The dosage is based on your medical condition and response to treatment. Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

Faq for ATENOLOL/CHLORTHALIDONE - ORAL
Atenolol/Chlorthalidone is a combination medication that is used for the treatment of high blood pressure (hypertension).
Atenolol is a beta-blocker that works by blocking the action of certain natural chemicals in the body, such as adrenaline, which helps to lower blood pressure and heart rate. Chlorthalidone is a diuretic that helps to reduce excess fluid in the body, thereby lowering blood pressure.
The medication is usually taken once daily in the morning, with or without food. It is important to take it consistently to get the most benefit. Follow the instructions provided by your doctor or pharmacist.
If you miss a dose, take it as soon as you remember. However, if it is close to your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not double the dose to make up for a missed one.
Common side effects may include dizziness, lightheadedness, tiredness, and upset stomach. Contact your doctor if you experience more severe side effects like fainting, slow or irregular heartbeat, mood changes, or difficulty breathing.
It is generally recommended to avoid alcohol while taking Atenolol/Chlorthalidone, as alcohol can increase the blood pressure-lowering effect of the medication.
No, you should not stop taking Atenolol/Chlorthalidone suddenly without consulting your doctor. Stopping this medication abruptly can cause a rebound increase in blood pressure and other withdrawal symptoms. Your doctor may need to gradually reduce the dose to safely discontinue the medication.
It is advised to discuss the risks and benefits with your doctor before taking Atenolol/Chlorthalidone during pregnancy or while breastfeeding. The medication may not be recommended in certain situations, depending on individual circumstances.
Atenolol/Chlorthalidone may interact with other medications, including NSAIDs, certain antidepressants, diabetes drugs, and other blood pressure-lowering medications. It is important to inform your doctor or pharmacist about all the medications you are taking to avoid potential interactions.
The blood pressure-lowering effects of Atenolol/Chlorthalidone may take a few weeks to fully develop. It is important to continue taking the medication as prescribed, even if you do not immediately feel its effects.
