Warnings/Precautions:

Renal dysfunction: reduce dose. Sinus node disease. Incomplete AV block. Accessory AV pathway (Wolff-Parkinson-White syndrome). Heart failure with preserved LV ejection fraction (eg, restrictive cardiomyopathy, constrictive pericarditis, amyloid heart disease, acute cor pulmonale, hypertrophic cardiomyopathy). Electrical cardioversion. Acute MI. Avoid in myocarditis. Toxicity risk increased by hypokalemia, hypomagnesemia, hypercalcemia, diabetes. Hypocalcemia may nullify effects. Thyroid disease.

Cardiac glycoside.

Interactions:

Toxicity risk increased by potassium-depleting drugs (eg, diuretics, amphotericin B, corticosteroids).

Digoxin levels decreased by thyroid hormones, antacids, kaolin-pectin, cholestyramine, neomycin, penicillamine, rifampin, sulfasalazine, drugs that increase GI motility (eg, metoclopramide), certain antineoplastics, others. Digoxin levels possibly affected by alprazolam, cyclosporine, diclofenac, others. Arrhythmias with sympathomimetics, succinylcholine, or rapid calcium infusion. Heart block with drugs that affect cardiac conduction (eg, calcium channel blockers, β-blockers). Increased risk of bradycardia with ivabradine.
