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 USP are a prescription beta-blocker available in 25 mg, 50 mg, and 100 mg strengths for oral use. The label describes atenolol as a beta1-selective (cardioselective) adrenergic receptor blocking agent.

The tablets are indicated for the treatment of hypertension, long-term management of angina pectoris due to coronary atherosclerosis, and management of hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality.

The label notes that atenolol is absorbed after oral dosing, is eliminated mainly by the kidneys, and may require caution in people with impaired renal function or in older adults. It also states that abrupt stopping can be harmful in patients with coronary artery disease.

Important warnings include possible worsening heart failure, bradycardia, heart block, bronchospasm in susceptible patients, masking of hypoglycemia or hyperthyroidism symptoms, and fetal harm during pregnancy.

Storage Information

Store at controlled room temperature 20°C to 25°C (68°F to 77°F).

Key Counseling Points

• Atenolol is a prescription beta-blocker used for high blood pressure, angina, and certain patients with acute myocardial infarction.
• Do not stop atenolol suddenly unless directed by the prescriber; abrupt discontinuation may worsen angina or trigger serious heart problems.
• Tell a healthcare professional if there is a history of heart failure, slow heart rate, heart block, or allergy to atenolol or any tablet ingredient.
• Use caution if there is asthma or another bronchospastic disease, because beta-blockers can cause breathing problems.
• Atenolol may mask warning signs of low blood sugar, such as a fast heartbeat, especially in people with diabetes or during fasting.
• The label warns that atenolol can mask some signs of hyperthyroidism and abrupt withdrawal may precipitate thyroid storm.
• Tell a healthcare professional about other medicines, especially verapamil, diltiazem, clonidine, disopyramide, amiodarone, digitalis glycosides, or catecholamine-depleting drugs.
• Patients with impaired renal function and older adults may need cautious dosing because the drug is eliminated mainly by the kidneys.
• Pregnancy and breastfeeding warnings are included in the label; infants exposed in utero or through breast milk may be at risk for bradycardia or hypoglycemia.
• Report symptoms such as marked dizziness, fainting, wheezing, shortness of breath, or very slow pulse.
