Inhibits Na+/K+-ATPase, increasing intracellular calcium, enhancing contractility (positive inotrope). Also slows AV conduction (vagomimetic).
NARROW therapeutic index. Monitor serum digoxin levels (target 1.0-2.0 ng/ml dogs). Toxicity: arrhythmias, anorexia, vomiting. Reduce dose in renal failure. Many drug interactions (quinidine, verapamil).
Species-specific contraindications and adverse-reaction reports for cats may differ from canine / feline reference data — consult the primary citations listed with each rule.

These are general warnings for Digoxin across species; consult the cat dosing table above for species-specific guidance. NARROW therapeutic index. Monitor serum digoxin levels (target 1.0-2.0 ng/ml dogs). Toxicity: arrhythmias, anorexia, vomiting. Reduce dose in renal failure. Many drug interactions (quinidine, verapamil).
Why a species-specific page? Digoxin pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cats — the rules above are the citations specific to this species, not generic recommendations.
