Digoxin

Question	Answer
Digoxin: CLASSIFICATION	Cardiac Glycoside
Digoxin: ACTION	Inhibits sodium-potassium ATPase, promoting increased force of cardiac contraction, cardiac output, and tissue perfusioin; Decreases ventricular rate
Digoxin: USES/ THERAPEUTIC EFFECTS	To treat HF, Atrial Fibrillation
Digoxin: SIDE EFFECTS	Anorexia, nausea, vomiting, diarrhea, abdominal pain, headache, blurred vision, diploopia, photophobia, drowsiness, dizziness, fatigue, confusion
Digoxin: ADVERSE REACTIONS	Bradycardia, visual disturbances LIFE-THREATENING: Atrioventricular block, cardiac dysrhythmias
Digoxin: CONTRAINDICATIONS	Ventricular dysrhythmias, 2nd or 3rd degree heart block CAUTION: AMI, renal disease, hypothyroidism, hyperthyroidism, hepatic dysfunction, bradycardia, hypokalemia
Digoxin: INTERACTIONS	Decreased absorption with antacids, colestipol; Increased risk for toxicity with thiazide diuretics, loop diuretics
Digoxin: MONITOR	Lab: Hypokalemia, hypomagnesemia, hypercalcemia can increase toxicity
Digoxin: ASSESSMENT	-obtain a drug and herbal history -low serum potassium enhances action of digoxin -obtain baseline pulse rate (apical should be >60) -assess signs/symptoms of toxicity
Digoxin: INTERVENTIONS	-don't admin. if pulse <60 -determine peripheral/pulmonary edema (indicates HF) -serum digoxin level >2 = toxicity -monitor potassium level <3.5=hypokalemia
Digoxin: PATIENT TEACHING	-teach to check pulse rate -watch for herb-drug interaction -eat foods high in potassium
