AB  - A 36-year-old man with schizophrenia, on two times per day clozapine, presented with a 2-year history of diffuse intermittent body pain.Per chart review—and on presentation—his physical examination had been consistently unremarkable, without point-tenderness elicited at any major muscle groups or focal neurological deficits. Workup for myopathy, neuropathy and supratherapeutic clozapine levels had similarly been unrevealing.Given that prior interventions had been unsuccessful in alleviating these symptoms, we queried whether clozapine might have been contributory. As a result, we adopted a previously described strategy of scheduling the bulk of patients’ medication during non-waking hours.At 1-month follow-up, the patient reported about a 50% improvement in his symptoms. At 6-month follow-up, this improvement in symptoms had been sustained.Our findings add to the limited anecdotal reports of this side effect whose true prevalence remains unknown. Timely recognition has the potential to promote adherence to therapy among patients in the maintenance phase.
