Sulphasalazine (SSZ) is a widely used second-line agent for several rh
eumatic diseases. Most of its side effects are relatively minor and do
se dependent. We report a patient with juvenile onset chronic arthriti
s who developed hepatotoxicity and seizures on the third week of SSZ w
hen the daily dose was increased to 2 g. Clinical and laboratory findi
ngs of liver and central nervous system toxicity gradually returned to
normal in the month following SSZ withdrawal.
