Atenolol 50 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 atherosclerosis, 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 body. This can lower heart rate and blood pressure and reduce the heart’s oxygen needs. The tablet is taken by mouth and comes in 25 mg, 50 mg, and 100 mg strengths.

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 against abrupt stopping of therapy, and it notes important cautions with heart failure, bronchospastic disease, diabetes-related hypoglycemia, thyroid disease, pregnancy, and breastfeeding.

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 prescribed.
• Do not stop taking it suddenly without medical guidance; abrupt stopping can worsen angina and has been linked with serious heart problems.
• Tell a healthcare professional right away if you notice symptoms of heart failure, such as worsening shortness of breath or swelling, because the label says this may require stopping the medicine.
• Be aware that atenolol can cause or worsen slow heart rate, low blood pressure, dizziness, tiredness, or light-headedness.
• The medicine may mask early warning signs of low blood sugar, such as a fast heartbeat, especially in people who are fasting, vomiting, or have diabetes.
• If you have bronchospastic disease such as asthma, the label says atenolol should be used with caution and a bronchodilator should be available.
• Tell a healthcare professional about other medicines you take, especially verapamil, diltiazem, clonidine, disopyramide, amiodarone, digoxin, or catecholamine-depleting drugs such as reserpine.
• Tell a healthcare professional if you are pregnant, may become pregnant, or are breastfeeding, because the label warns atenolol can cause fetal harm and may affect nursing infants.
• Keep follow-up appointments so blood pressure, pulse, and kidney function can be assessed when needed.
