Treatment of Cyanide Poisoning (Continued)

Dr. Berlin's schedule of treating cyanide poisoning by sodium nitrite and sodium thiosulfate should be in every emergency room and poison control center.1 It should also be included in Lilly's Cyanide Antidote Kit which contains these materials. (I have written the Eli Lilly Company concerning this.) Since cyanide is a spectacular poison and evokes such a frightening response and vigorous treatment, it is important to emphasize that ferrocyanide and ferricyanide as found in Turndall's Blue and Prussian Blue are of low toxicity (potential single adult fatal dose 50 gm).
