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 ADMINISTRATION ).

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 a prescription medicine containing atenolol, a beta1-selective beta-blocker. Each tablet is for oral use and contains 25 mg, 50 mg, or 100 mg of atenolol, along with inactive ingredients including magnesium stearate, microcrystalline cellulose, povidone, and sodium starch glycolate.
The label states atenolol is used to treat high blood pressure, help lower the risk of cardiovascular events linked to high blood pressure, manage long-term angina due to coronary atherosclerosis, and reduce cardiovascular mortality in hemodynamically stable patients with definite or suspected acute myocardial infarction.
The medicine should not be used in certain conditions, including sinus bradycardia, heart block greater than first degree, cardiogenic shock, overt cardiac failure, or a history of hypersensitivity to atenolol or any component of the product. The label also warns about abrupt stopping, which can worsen angina or trigger serious heart problems in some patients.
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
- This is a prescription atenolol tablet taken by mouth.
- The tablet strength may be 25 mg, 50 mg, or 100 mg.
- Atenolol is used for hypertension, long-term angina, and certain acute myocardial infarction patients.
- Do not stop atenolol abruptly; the label warns this may worsen angina or cause serious heart problems.
- Tell a healthcare professional about any history of heart block, slow pulse, heart failure, or hypersensitivity to atenolol.
- Atenolol can mask early warning signs of hypoglycemia, such as tachycardia.
- The label warns that bronchospastic disease patients generally should not receive beta-blockers, and atenolol should be used with caution if needed.
- The label warns about use with verapamil or diltiazem because bradycardia and heart block can occur.
- Atenolol should be used cautiously in patients with impaired renal function.
- Pregnancy and breastfeeding warnings are included in the label; atenolol may cause fetal harm and is excreted in human breast milk.
