Interactions between acetaminophen and Epitol (carbamazepine)
acetaminophen and carbamazepine (Moderate Drug-Drug)
MONITOR: Limited data suggest that carbamazepine may increase the potential hepatotoxicity of acetaminophen and decrease its pharmacologic effects. The mechanism may be related to accelerated CYP450 metabolism of acetaminophen with consequent increase of hepatotoxic metabolites. This interaction is of greatest concern in cases of acetaminophen overdose.
MANAGEMENT: Until more information is available, the use of this combination over a prolonged period of time should probably be avoided. Monitoring for clinical and laboratory evidence of hepatotoxicity is recommended.
