Seizures and hepatotoxicity following sulphasalazine administration.

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