HIGH ALERT
digoxin (Rx)

(di-jox′in)

APO-Digoxin
, Lanoxin

Func. class.:
Cardiac glycoside, inotropic, antidysrhythmic

Chem. class.:
Digoxin preparation

Do not confuse:
Lanoxin
/Lasix/Lonox/Lomotil/Xanax/Levoxine

ACTION:

Inhibits the sodium-potassium ATPase pump, which makes more calcium available for contractile proteins, thereby resulting in increased cardiac output (positive inotropic effect); increases force of contractions; decreases heart rate (negative chronotropic effect); decreases AV conduction speed

USES:

Heart failure, atrial fibrillation, atrial flutter, atrial tachycardia, cardiogenic shock, paroxysmal atrial tachycardia, rapid digitalization in these disorders

Unlabeled uses:
Atrial flutter, paroxysmal supraventricular tachycardia (PSVT) treatment/prophylaxis

CONTRAINDICATIONS:

Hypersensitivity to digoxin, ventricular fibrillation, ventricular tachycardia, carotid sinus syndrome, 2nd- or 3rd-degree heart block

Precautions:
Pregnancy (C), breastfeeding, geriatric patients, renal disease, acute MI, AV block, severe respiratory disease, hypothyroidism, sinus nodal disease, hypokalemia

IV route

• 
May be given undiluted or each 1 ml may be diluted in 4 ml of sterile water for injection, NS, D
5
W, or LR. Diluent volumes <4 ml will cause precipitation. Use diluted solutions immediately
