An 8-year-old boy with a known seizure disorder that was being treated
with lamotrigine developed acute hepatic failure. The patient, who ha
d been well previously, presented with jaundice, elevated liver enzyme
s, and a coagulopathy. After discontinuation of lamotrigine and aggres
sive resuscitation, the patient made an uneventful recovery. We believ
e that the hepatic failure in our patient was secondary to the use of
lamotrigine, We recommend careful monitoring of liver function when la
motrigine is administered. (C) 1998 by Elsevier Science Inc. All right
