Overview

According to the label, atenolol tablets are used to treat hypertension, to help lower blood pressure, and for the long-term management of angina pectoris due to coronary atherosclerosis. They are also indicated for hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality.

The label notes that atenolol may be used with other antihypertensive agents. It also states that blood pressure lowering is part of broader cardiovascular risk management.

Key Counseling Points

• This medicine is prescription only.
• Atenolol is a beta-blocker used for hypertension, angina, and certain patients with acute myocardial infarction.
• Do not stop atenolol suddenly; the label warns that abrupt discontinuation can worsen angina and may be associated with myocardial infarction or ventricular arrhythmias.
• The label says atenolol may cause or worsen slow heart rate, heart block, hypotension, or heart failure in some patients.
• Tell a healthcare professional about any history of asthma or other bronchospastic disease; the label says beta-blockers are generally avoided in these conditions, though atenolol may be used with caution in some cases.
• Atenolol may mask warning signs of hypoglycemia such as tachycardia, especially in patients who are fasting, vomiting, or have diabetes.
• The label warns that atenolol can mask some signs of hyperthyroidism and that withdrawal should be monitored closely if thyrotoxicosis is suspected.
• Use caution with other medicines that can slow heart rate or lower blood pressure, including verapamil, diltiazem, digitalis glycosides, clonidine, disopyramide, amiodarone, and catecholamine-depleting drugs.
• The label states atenolol should not be used in patients with sinus bradycardia, heart block greater than first degree, cardiogenic shock, overt cardiac failure, untreated pheochromocytoma, or hypersensitivity to atenolol or its components.
• Pregnancy and breastfeeding warnings are listed on the label, including potential fetal harm and possible effects in nursing infants.
