This report describes a patient with an acute intentional fluoxetine exposure who developed unique cardiovascular and neurovascular toxicity. The patient presented with lethargy and cardiac conduction delays (QRS 110 msec, QTc 458 msec) and developed a delayed seizure. On admission, therapy with intravenous sodium bicarbonate promptly narrowed the QRS to 90 msec. ⋯ At this time the bicarbonate infusion had been ceased and the QRS interval was not prolonged. The patient improved over time and no other apparent causes for the observed clinical effects could be discovered. Emergency physicians need to be aware of the uncommon occurrence of fluoxetine-induced cardiotoxicity and the potential benefit of sodium bicarbonate therapy.

Dystonic reactions are extrapyramidal motor dysfunctions that result from an insufficient activity of nigrostriatal dopamine and present clinically as spasms of the various muscle groups. Neuroleptic drugs are a known cause of dystonia and are the most frequently encountered trigger. ⋯ Fewer reports of dystonia as a direct result of cocaine use, independent of neuroleptics, are found in the literature. The cases of two acute dystonic reactions secondary to cocaine use are presented, with a discussion of the pathophysiology and treatment alternatives.
