Signs of digoxin overdose (toxicity)include nausea,vomiting,loss of appetite,diarrhea,and vision problems.Other signs include heart rate or rhythm changes,palpitations,and fainting.When these signs and symptoms occur,hold the dose,notify the prescriber,and check the patient's serum digoxin level.This drug has a very narrow therapeutic range (0.8 to 2 ng/mL).
