Amatoxin, a peptide contained in several mushroom species, accounts for the majority of severe mushroom poisonings by binding to RNA polymerase II irreversibly, leading to severe hepatonecrosis.
The course of amatoxin poisoning typically lasts 6-8 days in adults and 4-6 days in children in those that recover without transplantation. NAC is given initially in an intravenous (IV) loading dose of 150 mg/kg IV infused over 15 minutes, diluted in 200 mL of 5% dextrose in water (D5W); some recommend giving the loading dose over 60 minutes to reduce the risk of an anaphylactoid reaction.
