Atenolol 25 mg Tablets — Generic For Tenormin — TEVA

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 beta-blocker medicine used to treat high blood pressure, help manage angina due to coronary artery disease, and reduce cardiovascular mortality in hemodynamically stable patients with definite or suspected acute myocardial infarction.

The label says atenolol works by blocking beta1 receptors in the heart and can lower heart rate and blood pressure. It is taken by mouth, and the tablets contain atenolol plus inactive ingredients such as magnesium stearate, microcrystalline cellulose, povidone, and sodium starch glycolate.

The label also notes important warnings and precautions. Atenolol should not be stopped suddenly, and it may not be appropriate for people with certain heart conditions, very slow heart rate, serious conduction problems, untreated pheochromocytoma, or overt cardiac failure. It can also mask signs of low blood sugar and may affect breathing in people with bronchospastic disease.

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

• Take atenolol exactly as directed on the prescription label.
• Do not stop atenolol suddenly unless told to do so, because abrupt stopping can worsen angina or lead to heart problems.
• Atenolol can slow the heart rate and lower blood pressure.
• Tell the healthcare professional if there is a history of asthma or other bronchospastic disease, since the label says beta-blockers are generally not used in these patients.
• This medicine may mask warning signs of low blood sugar, such as a fast heartbeat.
• The label warns that patients with diabetes, fasting, vomiting, surgery, or children may be at higher risk for hypoglycemia.
• Tell the healthcare professional about all other medicines, including verapamil, diltiazem, clonidine, disopyramide, amiodarone, and digitalis glycosides, because interactions are described in the label.
• Let the healthcare professional know about pregnancy or breastfeeding, since the label warns about fetal harm and possible effects in nursing infants.
• The label says renal function should be evaluated in patients with hypertension or myocardial infarction.
• Report symptoms such as dizziness, fatigue, wheezing, shortness of breath, or very slow heartbeat if they occur.
• Store the medicine as directed on the package label.
