In which of the following poisoning is dimercaprol (BAL) contraindicated?
Dimercaprol will increase the excretion of cadmium, there is a concomitant increase in renal cadmium concentration, so that its use in case of cadmium toxicity is to be avoided. Dimercaprol also enhances the toxicity of selenium and tellurium, so it is not to be used to remove these elements from the body.
