摘要

Clozapine is the only second-generation antipsy-chotic that has proven efficacy greater than all other antipsychotics [1]. Somewhat ironically, it is also the antipsychotic with potentially the most dangerous side-effect profile, with agranulocytosis, gut dysmo-tility and seizures being potentially fatal side-effects. This has led to a degree of caution in its prescription. The first two of these are monitored by blood testing and clinical exam, respectively, but it is more difficult to predict if clozapine will induce a seizure in patients. A variety of approaches to reduce the risk of seizures are used clinically. The two most common methods are prophylaxis with sodium valproate if plasma levels >500 mug L or dosages are > 600 mg day[2]. There is no widely accepted international norm. This may be because the mechanism by which clozapine induces seizures is uncertain but clearly dose related [3], and for this reason clinicians have become increasingly conscious of this at high doses. Reported here is a case of clozapine-induced seizures and clinical response at low dose.
