Atenolol 50 mg Tablets — Generic For Tenormin — Unichem

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 beta1-selective beta-blocker used to treat high blood pressure, help manage angina due to coronary atherosclerosis, and reduce cardiovascular mortality in hemodynamically stable patients with definite or suspected acute myocardial infarction. Atenolol is available as oral tablets in 25 mg, 50 mg, and 100 mg strengths.

The label says atenolol lowers blood pressure and reduces heart rate and the heart’s oxygen demand. It may be used alone or with other antihypertensive medicines. In acute myocardial infarction, treatment can be started as soon as the patient’s clinical condition allows.

Atenolol 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 its components. The label also warns about abrupt stopping, use with some calcium channel blockers, bronchospastic disease, hypoglycemia, pregnancy, and breastfeeding.

Storage Information

Store at 20  to 25 C (68  to 77 F) [see USP Controlled Room Temperature].

Key Counseling Points

• Take atenolol exactly as directed on your prescription label.
• Do not stop atenolol suddenly without medical supervision; abrupt stopping can worsen angina and has been linked to serious heart problems.
• Tell your healthcare provider if you have asthma or another bronchospastic condition, since beta-blockers are generally avoided and atenolol should be used cautiously if needed.
• Watch for dizziness, tiredness, slow heartbeat, or light-headedness, which are reported side effects.
• Atenolol may hide early warning signs of low blood sugar, such as a fast heartbeat.
• People who are fasting, vomiting, or have diabetes may be at higher risk for hypoglycemia while taking atenolol.
• Tell your healthcare provider about all medicines you take, especially verapamil, diltiazem, clonidine, disopyramide, amiodarone, digitalis glycosides, or catecholamine-depleting drugs.
• Use caution if you have kidney problems, since the label says atenolol should be used carefully in impaired renal function.
• Tell your healthcare provider if you are pregnant, may become pregnant, or are breastfeeding.
• If you have a history of severe allergy, tell your healthcare provider because beta-blockers may make allergic reactions harder to treat.
