Renal Dysfunction

Major:

digoxin

Digoxin has a major potential interaction with Renal Dysfunction.

Digoxin is primarily eliminated by the kidney. Patients with renal impairment may be at increased risk for digoxin toxicity, including ventricular arrhythmias and AV conduction disturbances, due to decreased drug clearance. Therapy with digoxin should be administered cautiously in patients with impaired renal function. Dosage adjustments should be made according to product package labeling and patient attributes such as age, ideal body weight, and other concomitant disease states and medication usage. Dosage increments should be made very gradually, since the elimination half-life may be prolonged in these patients and a longer period of time is required to establish steady-state serum concentrations than normal. These patients should be monitored closely for manifestations of toxicity, and dosages further adjusted as necessary. If toxicity occurs, clinicians should be aware that the adverse effects may also be prolonged.

Sinus Node Dysfunction

Major:

digoxin

Digoxin has a major potential interaction with Sinus Node Dysfunction.
