Atenolol 25 mg Tablets — Generic For Tenormin — Rising Pharma

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 prescription beta-blocker tablets available in 25 mg, 50 mg, and 100 mg strengths for oral use. The label describes atenolol as a beta1-selective (cardioselective) adrenergic receptor blocking agent.

The tablets are indicated for treatment of hypertension to lower blood pressure, long-term management of angina pectoris due to coronary atherosclerosis, and management of hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality.

The label notes that atenolol is absorbed incompletely after oral dosing, is eliminated mainly by the kidneys, and may accumulate when kidney function is reduced. It also warns against abrupt discontinuation and includes important precautions for certain heart conditions, bronchospastic disease, diabetes, pregnancy, and breastfeeding.

Storage Information

Store at controlled room temperature 20°C to 25°C (68°F to 77°F).

Key Counseling Points

• Take atenolol exactly as prescribed on the label and by your healthcare professional.
• Do not stop atenolol abruptly; the label warns that sudden discontinuation can worsen angina and may lead to heart attack or rhythm problems.
• Tell your clinician if you have a history of slow heart rate, heart block, overt heart failure, cardiogenic shock, or allergy to atenolol or any tablet component.
• Use caution if you have asthma or other bronchospastic disease; the label says beta-blockers are generally not recommended in these patients.
• Atenolol may hide warning signs of low blood sugar, such as fast heartbeat, and may increase the risk of severe or prolonged hypoglycemia.
• Tell your clinician if you have diabetes, are fasting, not eating regularly, or are vomiting.
• The label warns that atenolol can cause fetal harm and may pass into breast milk; discuss pregnancy or breastfeeding with a clinician.
• Use caution if you have impaired kidney function, since atenolol is eliminated primarily by the kidneys and may accumulate.
• Be aware that dizziness, tiredness, cold extremities, bradycardia, and low blood pressure are among the reported adverse reactions.
• Ask about possible interactions if you take verapamil, diltiazem, clonidine, disopyramide, amiodarone, digoxin, or catecholamine-depleting drugs.
