Atenolol 100 mg Tablets — Generic For Tenormin — Aurobindo

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 used to treat high blood pressure, help manage angina pectoris due to coronary atherosclerosis, and treat hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality.

Atenolol is a beta1-selective beta-blocker. It works by reducing heart rate and lowering blood pressure, which can reduce the heart’s oxygen needs.

The label says atenolol tablets are available in 25 mg, 50 mg, and 100 mg strengths for oral use. Commonly listed inactive ingredients include sodium starch glycolate, crospovidone, povidone, silicified microcrystalline cellulose, and magnesium stearate.

Storage Information

Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) [see USP Controlled Room Temperature].

Key Counseling Points

• Take atenolol exactly as directed on the prescription label.
• Do not stop atenolol suddenly without medical direction; abrupt discontinuation may worsen angina or lead to serious heart problems.
• Tell a healthcare professional if you have a history of asthma or other bronchospastic disease, because beta-blockers may not be appropriate for everyone with breathing problems.
• Watch for signs of low heart rate or low blood pressure, such as dizziness, light-headedness, or fainting.
• Atenolol may hide early warning signs of low blood sugar, such as a fast heartbeat.
• Use caution if you have diabetes, are fasting, are vomiting, or are not eating regularly, because the label warns about hypoglycemia risk.
• Tell your healthcare professional about all other medicines, especially verapamil, diltiazem, clonidine, disopyramide, amiodarone, digitalis glycosides, or catecholamine-depleting drugs.
• Let a healthcare professional know if you are pregnant, plan to become pregnant, or are breastfeeding, because the label warns atenolol can cause fetal harm and may affect nursing infants.
• Use caution if you have kidney problems or are older, since the label says atenolol is eliminated mainly by the kidneys and may accumulate when renal function is reduced.
