Subsequently, carbamates have a similar toxicological presentation to OP poisonings with a duration of toxicity that is typically less than 24 hours [1]. Unfortunately, many doses of these antidotes may be required since the insecticide lasts a longer time in the body than the antidote. Common agents resulting in toxic exposure are aldicarb, carbofuran, carbaryl, ethinenocarb, fenobucarb, oxamyl, methomyl, pirimicarb, propoxur, and trimethacarb.
