Two patients receiving clozapine developed grand mal seizures. The
plasma levels in one of the patients at the time of the seizure were
approximately 100% higher than on 12 previous occasions. This finding led
to the conclusion and the patient's admission that she had taken an
overdose. Plasma levels in the other patient exceeded the range the authors
had noted in previous studies. The authors emphasize the usefulness of
plasma level monitoring in relation to safety, drug defaulting, and side
effects.Abstract Teaser
