3-Cysteinylacetaminophen is an acetaminophen-protein adduct formed during the metabolism of acetaminophen.[1],[2] 3-Cysteinylacetaminophen has been found in isolated human serum following therapeutic and supratherapeutic doses of acetaminophen and in the presence and absence of hepatotoxicity.[3],[4] In mice, 3-cysteinylacetaminophen decreases renal glutathione (GSH) levels, an effect that can be blocked by the γ-glutamyl inhibitor acivicin.
