Pregnancy: Category C. Lactation: Excreted in breast milk. Children: Safety not established. Anaphylaxis: Deaths have occurred; aggressive therapy may be required. CHF: Administer cautiously in patients with CHF controlled by digitalis and diuretics. Diabetes mellitus: May mask symptoms of hypoglycemia (eg, tachycardia, BP changes). Elderly: Dosage reduction may be necessary. Nonallergic bronchospastic diseases (eg, chronic bronchitis, emphysema): In general, do not give beta-blockers to patients with bronchospastic diseases.

Drug Mode of Action ::  

 Action Blocks beta receptors, primarily affecting heart (slows rate), vascular system (decreases BP) and, to lesser extent, lungs (reduces function).

Drug Interactions ::


Ampicillin: May impair antihypertensive and antianginal effects. Clonidine: May add to or reverse antihypertensive effects; potentially life-threatening situations may occur, especially on withdrawal. NSAIDs: Some agents may impair antihypertensive effect. Prazosin: May increase orthostatic hypotension. Verapamil: Effects of both drugs may be increased.

Drug Assesment ::


  • Obtain patient history, including drug history and any allergies. Note diabetes; respiratory, liver, or cardiac disease, or sensitivity to other beta-blockers.
  • Review baseline ECG.
