What is a toxic level of digoxin?

Ingestion of massive quantities of digitalis (in children, 4 mg or 0.1 mg/kg; in adults, 10 mg) Serum digoxin level greater than 10 ng/mL in adults at steady state (ie, 6-8 hours after acute ingestion or at baseline in chronic toxicity) Hyperkalemia (serum potassium level greater than 5 mEq/L)
A.

Can digoxin overdose cause death?

Acute massive digoxin overdose in this patient would have caused life threatening arrhythmias mainly atrioventricular conduction disturbances which led to immediate death. Also refractory hypokalaemia can contribute to the cause of death in digoxin poisoning.9.

    These symptoms include fatigue, malaise, and visual disturbances. The classic features of digoxin toxicity are nausea, vomiting, abdominal pain, headache, dizziness, confusion, delirium, vision disturbance (blurred or yellow vision).
  • What drugs interact with digoxin?

    Does Digoxin Interact with other Medications?
    • DIGITALIS GLYCOSIDES/QUINIDINE.
    • DIGITALIS GLYCOSIDES/AMPHOTERICIN B.
    • DIGOXIN, ORAL/MACROLIDE ANTIBIOTICS.
    • DIGOXIN/PROPAFENONE;FLECAINIDE.
    • DIGOXIN/CYCLOSPORINE.
    • DIGOXIN/VERAPAMIL; MIBEFRADIL.
    • DIGOXIN/HYDROXYCHLOROQUINE.
    • DIGITALIS GLYCOSIDES/INTRAVENOUS CALCIUM PRODUCTS.
  • What is the antidote for digoxin toxicity?

    Digibind
B.

What is the most common first sign of digoxin toxicity?

Digitalis toxicity produces CNS, visual, GI, and cardiac manifestations. Nausea, vomiting, and drowsiness are among the most common extracardiac manifestations. CNS symptoms of digitalis toxicity include the following: Drowsiness.
  • Which medication reverses digitalis toxicity?

    Therapeutic options range from simply discontinuing digoxin therapy for stable patients with chronic toxicity to digoxin Fab fragments, cardiac pacing, antiarrhythmic drugs, magnesium, and hemodialysis for severe acute toxicity.

C.

Is digoxin toxicity fatal?

The most common symptoms are gastrointestinal and include nausea, vomiting, abdominal pain and diarrhea. The cardiac manifestations are the most concerning and can be fatal. Digoxin toxicity can induce literally every arrhythmia except for rapidly conducted atrial arrhythmias (atrial fibrillation and atrial flutter).
  • What is the normal digoxin level?

    If you're receiving treatment for heart failure, the normal level of digoxin is between 0.5 and 2.0 nanograms of medication per milliliter of blood (ng/ml). If you're being treated for a heart arrhythmia, the normal level of the drug is between 1.5 and 2.5 ng/ml.
  • How long does it take for digoxin to get out of your system?

    The elimination half life of Digitek (digoxin) is 1.5 to 2 days.
  • Can digoxin cause ventricular tachycardia?

    The typical patient with digoxin overdose will present with extrasystoles (premature beats) and various degrees of AV block. A rather peculiar form of ventricular tachycardia may occur in digoxin intoxication, namely bidirectional ventricular tachycardia.
