Cessation of Therapy with Atenolol Patients with coronary artery disease, who are being treated with atenolol, should be advised against abrupt discontinuation of therapy. Severe exacerbation of angina and the occurrence of myocardial infarction and ventricular arrhythmias have been reported in angina patients following the abrupt discontinuation of therapy with beta-blockers. The last two complications may occur with or without preceding exacerbation of the angina pectoris. As with other beta-blockers, when discontinuation of atenolol is planned, the patients should be carefully observed and advised to limit physical activity to a minimum. If the angina worsens or acute coronary insufficiency develops, it is recommended that atenolol be promptly reinstituted, at least temporarily. Because coronary artery disease is common and may be unrecognized, it may be prudent not to discontinue atenolol therapy abruptly even in patients treated only for hypertension. (See DOSAGE AND ADMNISTRATION).

Medication Guide
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 prescription medicines available in 25 mg, 50 mg, and 100 mg strengths for oral use. Atenolol is a beta1-selective beta-blocker.
The label says atenolol is used to treat hypertension, to help lower blood pressure, and to manage angina pectoris due to coronary atherosclerosis. It is also indicated for hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality.
The medicine works by blocking certain beta-adrenergic receptors. The label notes that oral atenolol is absorbed incompletely, is eliminated mainly by the kidneys, and can build up when kidney function is reduced.
The label also lists important risks and warnings, including slow heart rate, heart block, worsening heart failure, bronchospasm in people with bronchospastic disease, masking of low blood sugar 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 hypertension, angina, and certain patients with acute myocardial infarction.
- Take it exactly as directed on the prescription label.
- Do not stop atenolol abruptly; the label warns that sudden discontinuation can worsen angina and may be associated with myocardial infarction or ventricular arrhythmias.
- Tell a healthcare professional if you have a history of slow heart rate, heart block, heart failure, or hypersensitivity to atenolol or its components.
- Use caution if you have bronchospastic disease; the label says beta-blockers are generally not recommended in these patients.
- The label warns that beta-blockers may mask early signs of hypoglycemia, such as tachycardia.
- Atenolol should not be used in untreated pheochromocytoma.
- Tell a healthcare professional if you are pregnant or breastfeeding; the label warns of fetal harm and possible effects in nursing infants.
- Let a healthcare professional know if you have impaired kidney function, since atenolol is eliminated primarily by the kidneys.
Helpful Patient Education
Atenolol tablets USP are a prescription beta1-selective beta-blocker available in 25 mg, 50 mg, and 100 mg strengths for oral administration. According to the DailyMed label, atenolol is indicated for the treatment of hypertension, the long-term management of angina pectoris due to coronary atherosclerosis, and for certain hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality.
This educational product information also notes important safety considerations, including the risk of bradycardia, heart block, worsening heart failure, bronchospasm in susceptible patients, masking of hypoglycemia symptoms, and fetal harm during pregnancy. Atenolol is eliminated primarily by the kidneys, so the label highlights caution in patients with impaired renal function.
