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 USP are available in 25 mg, 50 mg, and 100 mg strengths for oral use. Atenolol is a beta1-selective beta-blocker.
This medicine is indicated for the treatment of high blood pressure, for the long-term management of angina pectoris due to coronary atherosclerosis, and for use in 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 have prolonged effects in older adults or in people with impaired kidney function.
Storage Information
Store at controlled room temperature 20°C to 25°C (68°F to 77°F).
Key Counseling Points
- Atenolol is a beta-blocker used for hypertension, angina, and certain patients with acute myocardial infarction.
- The tablets are for oral administration and come in 25 mg, 50 mg, and 100 mg strengths.
- Do not stop atenolol abruptly; the label warns that sudden discontinuation can worsen angina and has been linked to myocardial infarction and arrhythmias.
- Tell a healthcare professional if there is a history of sinus bradycardia, heart block, cardiogenic shock, overt cardiac failure, or allergy to atenolol or tablet ingredients.
- Use caution if there is bronchospastic disease, because beta-blockers can affect the airways; the label says the lowest possible dose should be used and a bronchodilator should be available.
- Atenolol may mask early warning signs of hypoglycemia, such as tachycardia, especially during fasting, vomiting, or in diabetes.
- The label warns atenolol can mask signs of thyrotoxicosis and should not be used in untreated pheochromocytoma.
- Patients with impaired renal function may need caution because atenolol is eliminated primarily by the kidneys.
- The label notes possible interactions with calcium channel blockers, clonidine, disopyramide, amiodarone, catecholamine-depleting drugs, digitalis glycosides, and some prostaglandin synthase inhibitors.
