Atenolol Information

Atenolol (a ten' oh lole) Tenormin® Tenoretic® (as a combination product containing Atenolol and Chlorthalidone) Do not stop taking atenolol without talking to your doctor. Suddenly stopping atenolol may cause chest pain, heart attack, or irregular heartbeat. Your doctor will probably decrease your dose gradually.

Atenolol is used alone or in combination with other medications to treat high blood pressure. It also is used to prevent angina (chest pain) and improve survival after a heart attack. Atenolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure. High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

Atenolol comes as a tablet to take by mouth. It is usually taken once or twice a day. To help you remember to take atenolol, take it around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take atenolol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Atenolol controls high blood pressure and angina but does not cure them. It may take 1-2 weeks before you feel the full benefit of atenolol. Continue to take atenolol even if you feel well. Do not stop taking atenolol without talking to your doctor.

Before taking atenolol, tell your doctor and pharmacist if you are allergic to atenolol, any other medications, or any of the ingredients in atenolol tablets. Ask your pharmacist for a list of the ingredients. tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: calcium channel blockers such as diltiazem (Cardizem, Cartia XT, Dilacor XR, Tiazac, others) and verapamil (Calan, Covera-HS, Verelan, in Tarka); clonidine (Catapres, Kapvay, in Clorpres); nonsteroidal anti-inflammatory drugs (NSAIDs) such as indomethacin (Indocin, Tivorbex); and reserpine. Your doctor may need to change the doses of your medications or monitor you carefully for side effects. tell your doctor if you have or have ever had asthma or other lung diseases; diabetes; severe allergies; hyperthyroidism (an overactive thyroid gland); pheochromocytoma (a tumor that develops on a gland near the kidneys and may cause high blood pressure and fast heartbeat); heart failure; a slow heart rate; circulation problems; or heart or kidney disease. tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking atenolol, call your doctor immediately. if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking atenolol. you should know that if you have allergic reactions to different substances, your reactions may be worse while you are using atenolol, and your allergic reactions may not respond to the usual doses of injectable epinephrine.

If your doctor prescribes a low-salt or low-sodium diet, follow these directions carefully.

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

Keep all appointments with your doctor. Your blood pressure should be checked regularly to determine your response to atenolol. Your doctor may ask you to check your pulse (heart rate). Ask your pharmacist or doctor to teach you how to take your pulse. If your pulse is faster or slower than it should be, call your doctor. Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription. It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
