Therapeutic Use Increased cardiac output and slowing of the heart rate. Complications Fatigue, Arrhythmias, Bradycardia, Anorexia, Nausea, Vomiting Medication Administration PO(Adults) 0.75-1.5mg given as 50% of the dose initially and one quarter of the initial dose in each of 2 subsequent doses at 6-12hr intervals. Contraindications/Precautions Uncontrolled ventricular arrhythmias AV block Idiopathic hypertrophic subaortic stenosis Constrictive pericarditis Known alcohol intolerance Interactions Quinidine and ritonavir increase levels and lead to toxicity. Amiodarone may increase levels and lead to toxicity. Cyclosporine, itraconazole, propafenone, quinine, spironolactone and verapamil may increase levels and lead to toxicity. Additive bradycardia may occur with beta blockers, diltiazem and verapamil. Concurrent use of sympathomimetics may increase risk of arrthythmias. Thyroid hormone may decrease therapeutic effects. Evaluation of Medication Effectiveness Decrease in severity of HF. Increase in cardiac output Decrease in ventricular response to atrial tachyarrhythmias. ACTIVE LEARNING TEMPLATES Nursing Interventions Monitor apical pulse for 1 full minute before administering. Withhold and inform healthcare professional if pulse rate is <60bpm. Monitor BP periodically in patients. Monitor ECG throughout IV Administration and 6hrs after each dose. Monitor intake and output daily. Evaluate serum electrolyte levels and renal and hepatic functions periodically during therapy Client Education Teach patient to take pulse and to contact health care professional before taking medication if pulse rate <60 or >100.
