Tenoric Tablet (Atenolol + Chlorthalidone) | Used to Treat High Blood Pressure

Precaution

1. Use Only as Prescribed

Take Tenoric exactly as directed by your healthcare professional. Do not change the dose or treatment schedule without medical advice.

2. Monitor Blood Pressure

Regular blood-pressure checks may be recommended to determine how well the treatment is working and whether the dose needs adjustment.

3. Monitor Heart Rate

Atenolol can slow the heart rate. Tell your doctor if you develop an unusually slow pulse, dizziness, fainting, or unusual weakness.

4. Do Not Stop Suddenly

Do not discontinue Tenoric suddenly without medical advice, particularly if you have coronary artery disease. Sudden withdrawal of beta-blocker treatment can worsen angina and may cause serious cardiovascular complications.

5. Kidney Problems

Tell your doctor if you have kidney disease. Atenolol is eliminated mainly through the kidneys, and dosage adjustment may be required in significant renal impairment.

6. Monitor Electrolytes

Chlorthalidone can affect electrolyte levels, including potassium and sodium. Your healthcare professional may recommend blood tests during treatment.

7. Dehydration

Chlorthalidone increases urine production and can contribute to fluid loss. Drink fluids according to your healthcare professional's advice and report significant dizziness, weakness, or excessive thirst.

Usage 

Take Tenoric Tablet exactly as prescribed by your healthcare professional. It is generally taken orally once daily, but the appropriate dose depends on your blood-pressure response, kidney function, and overall treatment plan.

Official combination-product labeling describes 50 mg Atenolol/25 mg Chlorthalidone once daily as an initial combination dose for the labeled product, with 100 mg/25 mg once daily used when additional blood-pressure control is required. These doses are product-specific and should not be used for self-dosing.

Take the tablet consistently at approximately the same time each day. Because Chlorthalidone increases urine production, some people may prefer taking the medicine earlier in the day according to their healthcare professional's instructions.

Uses

1. High Blood Pressure

Tenoric is used to treat hypertension by combining the blood-pressure-lowering effects of Atenolol and Chlorthalidone.

2. Blood Pressure Control

The combination can help reduce elevated blood pressure through two different mechanisms: reducing cardiac activity and increasing the elimination of sodium and water.

3. Combination Antihypertensive Treatment

Tenoric provides Atenolol and Chlorthalidone in a single tablet for patients for whom this combination is considered appropriate.

4. Reduction of Cardiovascular Workload

By slowing the heart rate and lowering blood pressure, the combination reduces the workload placed on the cardiovascular system.

FAQs

1. What is Tenoric Tablet?

Tenoric Tablet contains Atenolol and Chlorthalidone, a beta-blocker and diuretic combination used to treat high blood pressure.

2. What is Tenoric Tablet used for?

Tenoric is used for the treatment of hypertension and helps lower elevated blood pressure.

3. How does Tenoric work?

Atenolol slows the heart rate and reduces the workload of the heart, while Chlorthalidone increases the removal of sodium and water through urine. Together, these actions help lower blood pressure.

4. Is Tenoric a beta-blocker?

Tenoric contains Atenolol, which is a beta-1-selective beta-blocker. It also contains Chlorthalidone, a diuretic.

5. Does Tenoric increase urination?

Chlorthalidone is a diuretic and increases the excretion of sodium and water, which can increase urine production.

6. Can Tenoric lower blood pressure too much?

Yes. Excessive blood-pressure reduction can cause dizziness, light-headedness, or fainting. Contact your healthcare professional if these symptoms are severe or persistent.

7. Can Tenoric slow the heart rate?

Yes. Atenolol slows the heart rate. An unusually slow pulse accompanied by dizziness, fainting, or weakness should be reported to a healthcare professional.

Interactions

1. Other Blood Pressure Medicines

Using Tenoric with other medicines that lower blood pressure can cause an excessive reduction in blood pressure. Your doctor may need to monitor your response when treatments are combined.

2. Calcium Channel Blockers

Medicines such as verapamil or diltiazem can have additive effects on heart rate and cardiac conduction when combined with beta-blockers. This may increase the risk of bradycardia or heart block.

3. Other Medicines That Slow the Heart

Other medicines that reduce heart rate may increase the heart-rate-lowering effects of Atenolol.

4. Diabetes Medicines

Atenolol can affect the recognition of some low-blood-sugar symptoms. Blood glucose may require closer monitoring when beta-blockers are used with insulin or other diabetes medicines.

5. Digoxin

Digoxin can slow the heart rate and affect cardiac conduction. Combined use with Atenolol may increase these effects.

6. Clonidine

Clonidine and beta-blockers both affect blood pressure and heart rate. Changes to either medicine should be made under medical supervision.

7. Antiarrhythmic Medicines

Some medicines used to treat abnormal heart rhythms may have additive effects on heart rate or cardiac conduction when combined with Atenolol.
