Management of cardiac drug overdose.
Although overdoses from cardiac drugs are uncommon, these are compounds with narrow therapeutic indices and they may give rise to serious acute toxicity from accidental, deliberate or even iatrogenic overdosage. Through the National Poisons Information Service for England and the Poisons Unit laboratory, we monitor reports of serious toxicity from this group of drugs and use the information gained to assess our recommendations for treatment. This article reviews the toxicity and the management of overdosage with digoxin and representative drugs from each class of anti-arrhythmic drugs. From these observations, a general plan of management applicable to all cardiac drugs is proposed and its is suggested that this form of monitoring should be continued.
