During morning rounds on the inpatient psychiatric unit, a medical team is evaluating a patient with schizoaffective disorder. The 34-year-old man's psychotic symptoms were previously refractory to numerous medication trials but are now well-controlled on clozapine. However, over the past week, the nursing staff reports that he has become increasingly hyperactive and irritable, pacing the halls and sleeping less than two hours per night. The team diagnoses an acute manic episode and decides to initiate an additional mood-stabilizing medication. A review of his morning laboratory results shows an absolute neutrophil count of 2,800/mm³. Which of the following medications should the team strictly avoid prescribing due to the risk of a synergistic and potentially life-threatening adverse effect?
