Tenoretic contains two active ingredients: atenolol and chlorthalidone. It is a prescription medication used to treat high blood pressure (hypertension).
Tenoretic is used to help lower blood pressure in adults with hypertension.
High blood pressure means the force of blood against the walls of the arteries remains higher than normal over time.
If it is not controlled, high blood pressure can increase the risk of serious health problems such as:
Lowering blood pressure helps reduce the risk of cardiovascular complications.
Tenoretic combines two blood pressure medications that work in different ways.
The two ingredients are:
Their blood-pressure-lowering effects work together.
How Atenolol Works
Atenolol is a beta-1 selective beta blocker.
It blocks certain effects of adrenaline on the heart.
This helps:
How Chlorthalidone Works
Chlorthalidone is a diuretic, sometimes called a water pill.
It helps the kidneys remove extra sodium and water from the body through urine.
Reducing excess fluid can lower the amount of fluid circulating through the blood vessels, which helps reduce blood pressure.
How the Combination Helps
Atenolol and chlorthalidone lower blood pressure through different mechanisms.
Using them together can provide a stronger blood-pressure-lowering effect than either medication alone in some people.
Tenoretic is not specifically indicated for the treatment of angina.
Although atenolol alone may be prescribed for angina, Tenoretic is primarily used for hypertension because it combines atenolol with chlorthalidone.
Your healthcare provider will decide whether this combination is appropriate based on your blood pressure, heart health, kidney function, and other medications.
Tenoretic is taken by mouth, usually once daily, exactly as prescribed by your healthcare provider.
You may take Tenoretic with or without food, but try to take it the same way each day.
Because Tenoretic contains chlorthalidone, a diuretic or “water pill,” taking it earlier in the day may help reduce the need to urinate during the night.
Starting dose: One Tenoretic 50 tablet once daily.
Each Tenoretic 50 tablet contains:
This is the usual initial dose for treating high blood pressure.
If your blood pressure is not adequately controlled, your healthcare provider may increase the dose to:
Maximum recommended dose: One Tenoretic 100 tablet once daily.
Each Tenoretic 100 tablet contains:
The dose should be individualized based on your blood pressure and response to treatment.
Atenolol is removed mainly through the kidneys.
If you have significantly reduced kidney function, your healthcare provider may need to lower the dose or adjust how often you take the medication.
Kidney function may be monitored during treatment, especially if you already have kidney disease.
Take Tenoretic at about the same time each day.
Taking it regularly helps maintain a steady blood-pressure-lowering effect.
Do not take more than prescribed or change your dose without speaking with your healthcare provider.
Cholestyramine and colestipol can reduce the absorption of some medications.
If you take either of these cholesterol-lowering medicines, your healthcare provider or pharmacist may recommend separating them from Tenoretic by several hours.
Follow the timing instructions they provide.
If you miss a dose of Tenoretic, take it when you remember unless it is almost time for your next scheduled dose.
If your next dose is approaching, skip the missed dose and continue with your regular schedule.
Do not take two doses at the same time to make up for a missed dose.
Your healthcare provider may monitor your:
Contact your healthcare provider if you feel unusually dizzy, faint, or very weak or notice other concerning symptoms while taking Tenoretic.
Tenoretic (Atenolol/Chlorthalidone) is available in the following forms and strengths:
The safety and effectiveness of Tenoretic have not been established in children.
Tenoretic is generally prescribed for adults, and use in younger patients should only occur if a healthcare provider specifically recommends it.
Tenoretic can cause dizziness, lightheadedness, or fainting, especially when treatment is first started or the dose is changed.
Stand up slowly from a sitting or lying position.
Avoid driving, operating machinery, or doing other activities that require full alertness until you know how Tenoretic affects you.
Tenoretic should be used with caution in people with reduced kidney function.
Atenolol is removed mainly through the kidneys, and chlorthalidone can also affect fluid and electrolyte balance.
Your healthcare provider may monitor your kidney function and adjust your treatment if needed.
The chlorthalidone in Tenoretic can change the levels of electrolytes in your blood.
Possible problems include:
Symptoms may include muscle weakness, cramps, unusual tiredness, dizziness, thirst, or an irregular heartbeat.
Your healthcare provider may order blood tests to monitor your electrolyte levels during treatment.
Tenoretic can affect blood sugar control.
Chlorthalidone may increase blood sugar in some people, while atenolol can mask certain warning signs of low blood sugar, such as a rapid heartbeat.
If you have diabetes, monitor your blood sugar as directed and tell your healthcare provider if your readings change significantly.
Atenolol is a beta blocker and can sometimes worsen breathing problems in people with asthma or other bronchospastic conditions.
Tell your healthcare provider if you have asthma, chronic bronchitis, emphysema, or another breathing disorder.
Tenoretic may still be used cautiously in some people when other blood pressure treatments are not suitable.
Because atenolol slows the heart rate and reduces the heart’s workload, Tenoretic may worsen certain heart conditions in some people.
Tell your healthcare provider if you have:
Contact your healthcare provider if you develop increasing shortness of breath, swelling, fainting, or an unusually slow heartbeat.
Do not suddenly stop taking Tenoretic without speaking with your healthcare provider.
Abruptly stopping a beta blocker such as atenolol can worsen chest pain and, in people with coronary artery disease, may increase the risk of a heart attack.
Your healthcare provider may gradually reduce your dose when treatment needs to be stopped.
Tenoretic can interact with other medications.
Tell your healthcare provider about all prescription medications, over-the-counter products, vitamins, supplements, and herbal products you use.
Particular caution may be needed with other blood pressure medications, certain heart medications, diabetes treatments, NSAIDs, lithium, and medications that affect potassium or fluid balance.
Tenoretic can affect blood sugar, electrolyte levels, kidney function, and other laboratory results.
Tell your healthcare provider and laboratory staff that you take Tenoretic before having blood tests or other medical testing.
Do not take Tenoretic if you have had a serious allergic reaction to atenolol, chlorthalidone, or any ingredient in the medication.
Seek immediate medical attention if you develop:
These may be signs of a serious allergic reaction.
During treatment, your healthcare provider may monitor your:
Regular monitoring helps make sure Tenoretic remains safe and effective for you.
Tenoretic begins working within hours of taking a dose. Atenolol reaches its highest blood level about 2 to 4 hours after a dose, and its blood-pressure-lowering effect can last for at least 24 hours. However, it may take longer to see the full effect of treatment on your blood pressure. Continue taking Tenoretic every day as prescribed, even if you do not notice an immediate change.
No. Do not suddenly stop taking Tenoretic without speaking with your healthcare provider. Tenoretic contains atenolol, a beta blocker. Abruptly stopping beta-blocker treatment can worsen chest pain and may increase the risk of serious heart problems, especially in people with coronary artery disease. Your healthcare provider may gradually reduce your dose when treatment needs to be stopped.
Tenoretic should only be used during pregnancy when your healthcare provider determines that the expected benefit outweighs the potential risk. Atenolol crosses the placenta and can affect a developing baby. Use beginning in the second trimester has been associated with babies being small for their gestational age, and the possibility of fetal harm cannot be excluded during earlier pregnancy. Babies exposed to atenolol close to delivery may also be at risk of a slow heart rate or low blood sugar after birth. Tell your healthcare provider if you are pregnant, planning to become pregnant, or become pregnant while taking Tenoretic.
