A patient on digoxin therapy accidentally consumes 8 tablets of digoxin 0.25 mg. Two hours later, he presented to the emergency doctor with a heart rate of 54 bpm and ECG evidence of third-degree AV block. What is the immediate management of this patient?

• A. Digoxin immune fab
• B. Lignocaine
• C. Phenytoin
• D. DC cardioversion

Hint:

Digoxin immune fab is the specific antidote for digoxin toxicity and is used in cases of severe toxicity with symptoms such as heart block and bradycardia.

Answer 1

The Correct Option is A

In this scenario, the immediate management of the patient is to administer Digoxin immune fab. This is a specific antidote for digoxin toxicity, especially in cases with life-threatening symptoms like bradycardia and third-degree heart block. The use of Digoxin immune fab can rapidly reverse the toxic effects of digoxin and improve the patient's condition. Lignocaine, Phenytoin, and DC cardioversion may be considered for arrhythmias, but the primary treatment in digoxin toxicity is Digoxin immune fab.
