What is Atenolol (Tenormin)?

What is Atenolol (Tenormin) used for?

How Atenolol (Tenormin) works

Atenolol (Tenormin) is a cardioselective beta-blocker. It slows down heart rate so your heart doesn't have to work as hard to pump blood through the body. This puts less stress on the blood vessels, which lowers blood pressure. Atenolol (Tenormin) also improves blood flow to the heart, which eases chest pain.

Pharmacist tips for Atenolol (Tenormin)

pharmacist
  • Atenolol (Tenormin) can cause dizziness, which could lead to falls. Make sure to sit or lie down if you feel dizzy to prevent accidental injuries. Don't drive a car or operate machinery until you know how atenolol (Tenormin) affects you.

    • If you're taking atenolol (Tenormin) for your blood pressure, you can track how well it's working by checking your blood pressure regularly at home. Write down your blood pressure readings, and bring them to your appointments with your provider so you can discuss how well atenolol (Tenormin) is working for you.

      • Don't take atenolol (Tenormin) if you're pregnant since it can cause low blood sugar or slow heart rate to the unborn baby. If you're pregnant or thinking of getting pregnant during treatment, contact your provider right away. Your provider might prescribe you a different medication that's safer during pregnancy or suggest lifestyle changes.

        • Consider avoiding alcohol while taking atenolol (Tenormin) because taking the two together can make you more drowsy and dizzy. If you drink alcohol regularly and it's difficult to stop completely, talk with your provider about what's a safer amount to drink.

          • If you have diabetes, be careful taking atenolol (Tenormin), since this medication can hide symptoms of low blood sugar, except for sweating and dizziness.

            • Don't stop taking this medication suddenly unless your provider tells you to. Stopping atenolol (Tenormin) all of a sudden cause your blood pressure to go up, which can raise the risk of heart attack and stroke. If you want to stop this medication, your provider can lower your dose slowly over time.

              faqs

              Frequently asked questions about Atenolol (Tenormin)

              How long does it take for atenolol (Tenormin) to lower heart rate?
              Studies show that atenolol (Tenormin) can start to lower exercise tachycardia (fast heart rate from exercise) within an hour after your dose. And you'll see a more noticeable effect on heart rate around 2 to 4 hours after a dose. But if you're taking atenolol (Tenormin) for blood pressure you might not see the full effects of this medication until about 1 to 2 weeks after you start. To make sure atenolol (Tenormin) is working well for you, your provider might ask you to check your heart rate and blood pressure regularly while taking this medication. Keep in mind that it might take a few weeks for your provider to find a dose that works for you. Make sure to follow the titration schedule as directed by your provider.
              How to stop taking atenolol (Tenormin) safely?
              If you need to stop taking atenolol (Tenormin) for any reason, let your provider know. Don't suddenly stop atenolol (Tenormin) because this not only raises your risk of high blood pressure and chest pain, but also your risk of having a heart attack. Your provider can help you stop atenolol (Tenormin) safely by lowering your dose slowly over time.
              How long does atenolol (Tenormin) stay in your system?
              It can take between 1 to 2 days for most of atenolol (Tenormin) to leave your body. But it can take much longer for older adults and people with kidney problems. Keep in mind that this time frame is estimated based on the half-life of atenolol (Tenormin). It can also be affected by your health conditions and genetics, so it can be different for each individual person. Talk with your provider if you have more questions about how long atenolol (Tenormin) stays in your system.
              Is it ok to take atenolol (Tenormin) twice a day?
              Atenolol (Tenormin) is only FDA-approved to be taken once daily for high blood pressure and chest pain. If you're taking atenolol (Tenormin) after a heart attack, your provider might ask you to take it twice daily for a short period of time. Don't stop, start, or change how your take your blood pressure or heart medications on your own without first speaking to your provider.
              What is the maximum dose of atenolol (Tenormin) per day?
              The maximum dose of atenolol (Tenormin) is different depending on what medical condition you're taking it to treat. For example, the maximum dose of atenolol (Tenormin) to treat high blood pressure is 100 mg once daily. On the other hand, the maximum dosage for chest pain is 200 mg of atenolol (Tenormin) once daily. In either condition, your provider will typically start you at 50 mg once daily and raise your dose every few weeks until your blood pressure or chest pain is controlled. Don't adjust the dose of atenolol (Tenormin) without talking to your provider.
              Does atenolol (Tenormin) cause weight gain?
              Even though it's not common, atenolol (Tenormin) might cause some weight gain as a side effect. This is because beta blockers, such as atenolol (Tenormin), have been shown to slow down metabolism, which can lead to weight gain. In addition, beta blockers can also cause you to be more tired, which can make it harder for you to exercise. To minimize weight gain, try to stick with an exercise routine that works for you. Talk with your provider if you have more questions about atenolol (Tenormin) and weight gain.
              Can I take atenolol (Tenormin) as needed for anxiety?
              According to the American Psychiatric Association, atenolol (Tenormin) can be prescribed off-label for performance-only social anxiety, such as public speaking. The typical dose is to take 50 mg to 150 mg by mouth 1-2 hours before an event that causes anxiety. Keep in mind that atenolol (Tenormin) doesn't work against generalized social anxiety. Ask your provider if atenolol (Tenormin) is appropriate for you.
              What's the difference between atenolol (Tenormin) and metoprolol?
              Atenolol (Tenormin) and metoprolol tartrate (Lopressor) are both cardioselective beta-blockers that can help lower blood pressure, ease chest pain, and to lower the risk of death after a heart attack. One main difference is that atenolol (Tenormin) is typically taken once daily, whereas metoprolol tartrate (Lopressor) is taken twice daily. But metoprolol does come in an extended-release version called metoprolol succinate (Toprol XL) that's taken once daily. Talk with your provider if you have more questions about the differences between atenolol and metoprolol.

              What are the risks and warnings for Atenolol (Tenormin)?

              Atenolol (Tenormin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

              risk-warning

              Worsening chest pain, heart attacks, and irregular heartbeat

              • Risk factors: Stopping atenolol (Tenormin) suddenly | History of coronary artery disease (CAD)

                Don’t stop taking atenolol (Tenormin) suddenly since it can worsen your chest pain, heart attack, or irregular heartbeat. If you need to stop taking this medication for any reason, let your provider know. They can work with you to lower your dose safely over time. While your dose is being lowered, make sure to limit physical activity as much as possible to lower the stress on your heart. Watch out for symptoms of heart attack (e.g., chest pain and tightness, pain that spreads to arms and neck, trouble breathing, lightheadedness, and fatigue) and irregular heartbeat (e.g., chest pain, fast heartbeat, dizziness, nausea). Get medical attention right away if you have any of these symptoms.

                risk-warning

                Heart failure

                • Risk factors: Heart failure | Sudden heart attack

                  Atenolol (Tenormin) might lead to heart failure or worsen heart failure in people who already have it. This is because atenolol (Tenormin) can slow down your heart, which leads to your heart muscle not pumping as often. In people with a history of heart problems, this can cause their heart to not work as well, leading to heart failure. People with heart failure shouldn't take atenolol (Tenormin) if their heart failure symptoms aren’t well-managed. Discuss with your provider before starting atenolol (Tenormin) if you have a history of heart failure. Let your provider know right away if you experience symptoms such as trouble breathing, tiredness, swelling in your body, or sudden weight gain. Your provider might ask you to stop this medication if you have symptoms of heart failure.

                  risk-warning

                  Risk of difficulty breathing

                  • Risk factors: Chronic obstructive pulmonary disease (COPD) | Asthma

                    Atenolol (Tenormin) can cause the vessels in your lung to tighten. This can make breathing difficult, especially in people with breathing problems, like asthma. This problem is very rare with atenolol (Tenormin) because it's a cardioselective beta-blocker, meaning it targets your heart rather than your lungs. To be safe, make sure your provider knows about your full medical history before starting this medication. Your provider will start you on the lowest dose possible that works well for you.

                    risk-warning

                    Greater risk during surgery

                    • Risk factor: Major surgery requiring anesthesia

                      If you're planning to undergo a major surgery requiring anesthesia, tell your surgeon that you are taking atenolol (Tenormin). Beta-blockers, such as atenolol (Tenormin), might raise the risk of side effects from anesthesia. If you've been taking it for a while, your surgeon might not ask you to stop it, but they'll need to monitor your heart closely during your procedure.

                      risk-warning

                      Hiding symptoms of low blood sugar

                      • Risk factors: Diabetes

                        Taking atenolol (Tenormin) can make it difficult for you to identify some symptoms of low blood sugar, such as fast heart beat or tremors. If you’re taking blood sugar medications, you might not be able to rely on all the typical symptoms of low blood sugar to warn you of a dangerous drop in your sugar levels. Watch out for sweating and dizziness, which aren't affected by atenolol (Tenormin), to identify low blood sugar episodes. If you have diabetes, speak with your provider about how often to monitor your blood sugar once you start atenolol (Tenormin).

                        risk-warning

                        Hiding symptoms of overactive thyroid

                        • Risk factor: Hyperthyroidism

                          If you have hyperthyroidism (overactive thyroid), talk to your provider before stopping atenolol (Tenormin). This is because atenolol (Tenormin) lowers your heart rate, which makes it harder to notice heart-related symptoms that are caused by hyperthyroidism. In some people, stopping this medication suddenly might lead to a condition called a "thyroid storm,” which include symptoms such as a high temperature, rapid heartbeat, and fainting. Get medical attention right away if you have these symptoms.

                          risk-warning

                          Risk of heart block (medication interaction)

                          You should avoid taking atenolol (Tenormin) with certain calcium channel blockers (CCBs), like diltiazem (Cardizem) or verapamil. Doing so can raise the risk of dangerously low heart rate and heart block.

                          risk-warning

                          Risk of harm to unborn and breastfed babies

                          • Risk factors: Currently in second trimester of pregnancy | Breastfed baby

                            Atenolol (Tenormin) can cause slow heart rate and low blood sugar to your breastfed baby or unborn baby if it's taken after second trimester of pregnancy. Speak to your provider about the risks and benefits of atenolol (Tenormin) if you're pregnant or breastfeeding. Ask them whether there are safer alternatives.
