Always double-check dosing of any drug and consult a pharmacist when necessary. Additional considerations for treatment of digoxin toxicity include: Atropine 0.
Cautious correction of electrolyte abnormalities, specifically hypokalemia and hypomagnesemia may result in dysrhythmias at lower serum digoxin levels. When to Use. Why Use. General: Acute, acute on chronic, or chronic digoxin toxicity. Poisoning with cardioactive steroid. Specific indications: Any digoxin-related life-threatening dysrhythmia independent of digoxin level. Elevated serum digoxin level, chronic digoxin toxicity associated with dysrhythmias, significant gastrointestinal symptoms, or altered mental status.
Poisoning with a non-digoxin cardioactive steroid e. Cardioactive steroid toxicity can cause nearly any dysrhythmia with the exception of a rapidly conducted supraventricular tachydysrhythmia.
Digoxin levels measured after administration of DigiFab will be falsely elevated. If required, free digoxin levels will need to be measured not readily available at all labs. Hyperkalemia acts as a marker of poisoning severity in acute digoxin overdose. Correcting mild elevations in serum potassium without administering DigiFab will not improve survival see Next Steps for details. Impaired creatinine clearance and aging associated with decreased function of renal, hepatic, and cardiac systems may result in clinical toxicity at lower serum digoxin levels.
Electrolyte abnormalities specifically hypokalemia, but including hypomagnesemia, hypercalcemia, hypernatremia may result in dysrhythmias at lower serum digoxin levels. Drugs including quinidine, verapamil, diltiazem, carvedilol, amiodarone, and spironolactone will result in decreased digoxin protein binding, thereby increasing free digoxin levels.
