Baclofen is a γ-aminobutyric acid (GABA) agonist that is commonly prescribed for the treatment of spasticity in children. The clinical indications for baclofen use in the pediatric population have increased in recent years. Prescribing baclofen mandates education regarding abrupt withdrawal and overdose because of the severe clinical reactions this can precipitate. This report highlights the case of a patient who presented with acute onset of coma and a flaccid paralysis after baclofen overdose. We reviewed the presentation, clinical course, diagnostic studies, and outcome of this patient. A review of prior literature regarding baclofen overdose is included. Baclofen overdose is heralded by dose-related alteration in consciousness and weakness, progressing to coma and a flaccid paralysis.
