Poisoning with Veratrum-containing sneezing powders.

1 Nine cases of accidental poisoning of children with sneezing powder are reported. Symptoms, besides sneezing, included gastrointestinal disturbances and syncope, whilst examination demonstrated bradycardia and hypotension. 2 The powder, as supplied, carried no information on its constituents but Veratrum alkaloids were identified on analysis. The signs and symptoms observed were compatible with poisoning from these compounds. 3 As a result of these observations, it was possible to trace the manufacturers and a change was made to a safer formulation. This example emphasises the value of toxic vigilance by Poison Control Centres.
