Atenolol 50 mg Tablets — Generic For Tenormin — TEVA

Medication Summary

Medication Summary: This section summarizes DailyMed drug label information to make the label easier to understand. It is not a substitute for the official label, pharmacist counseling, prescriber instructions, or medical advice.

Overview

Atenolol tablets are a prescription medicine containing atenolol, a beta1-selective beta-blocker. The label says the tablets are available in 25 mg, 50 mg, and 100 mg strengths for oral use.

Atenolol tablets are indicated to treat high blood pressure, help manage long-term angina pectoris due to coronary atherosclerosis, and help manage hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality.

The label describes atenolol as lowering heart rate and blood pressure and reducing the heart’s oxygen needs. It also notes that atenolol is eliminated mainly by the kidneys, so kidney function is an important consideration in use.

Storage Information

Storage Store at 20° to 25°C (68° to 77°F) [See USP Controlled Room Temperature]. Dispense in a tight, light-resistant container as defined in the USP, with a child-resistant closure (as required).

Key Counseling Points

• Take atenolol exactly as directed on the prescription label.
• Do not stop atenolol abruptly; sudden stopping can worsen angina and has been linked with heart attack and abnormal heart rhythms.
• Tell your healthcare provider if you have a history of asthma or other bronchospastic disease, heart failure, slow heart rate, heart block, or a history of allergy to atenolol or its ingredients.
• Atenolol can mask warning signs of low blood sugar, such as a fast heartbeat, and may increase the risk of severe or prolonged hypoglycemia.
• Use caution if you take other medicines that can slow the heart or lower blood pressure, including verapamil, diltiazem, digoxin, disopyramide, amiodarone, clonidine, or catecholamine-depleting drugs.
• Inform your healthcare provider if you are pregnant, planning pregnancy, or breastfeeding, because the label warns atenolol can cause fetal harm and may pass into breast milk.
• If you have kidney problems or are older, the label notes dose selection should be cautious and renal function should be evaluated.
• Report symptoms such as dizziness, faintness, wheezing, shortness of breath, unusual tiredness, slow pulse, or signs of heart failure promptly.
• Tell your healthcare provider if you have diabetes or may be fasting, vomiting, or not eating regularly, since these situations can raise the risk of hypoglycemia.
• If surgery is planned, tell the surgical team you are taking atenolol; the label notes beta-blocker therapy is not routinely withdrawn before major surgery.
