Abstract Severe poisoning resulting from single ingestions of rodenticides, herbicides, or insecticides containing arsenic have been frequently recognized. We record three cases of solubilized arsenic trioxide poisoning in Navajo Indian children and one case of sodium arsenate ingestion in an infant. One fatality occurred during dimercaprol therapy prior to initiation of therapy with D-penicillamine. Three survivors were treated with 2.3-dimercaprol intramuscularly and with oral D-penicillamine. The use of D-penicillamine in arsenic poisoning has not been generally appreciated. Excretion data from the three children are presented which document the effectiveness of D-penicillamine, administered orally in four daily doses of 25 mg/kg/dose, in the therapy of arsenic intoxication. Excretion data for the trace metals, zinc and copper, during D-penicillamine chelation therapy are also reported.
