The proconvulsive properties of tramadol, bupropion, and nortriptyline have been well documented. Spinal fractures secondary to drug-induced seizures have been rarely reported. ⋯ Sudden onset of back pain during sleep can be an important clue to a seizure complicated by vertebral compression fractures, even in the absence of trauma. Toxicology consultation in seizures of unclear etiology can help discern drugs that offend even in therapeutic doses.

Unintentional bupropion pediatric exposures uncommonly report severe clinical effects such as seizures. We sought to determine the clinical effects and case outcomes for unintentional bupropion ingestions in children age =6 years. The National Poison Data System was queried for unintentional, acute, single substance bupropion ingestions in children age =6 years for the time period January 1, 2000 to February 27, 2007 for cases followed to a known outcome. ⋯ A mg/kg dose was calculable in 76.1% of cases; the average amount for the no effect/minor cases and moderate/major effect was 13.8 +/- 18.8 and 38.8 +/- 44.0 mg/kg, respectively (p < 0.0001). Average time until development of seizures was 4.2 +/- 3.2 h with a maximum of 14 h. Few children develop toxicity from unintentional reported bupropion ingestions, with about 1.5% of patients developing an ANE.

Propafenone is an anti-arrhythmic drug used in the management of supraventricular and ventricular arrhythmias. It is metabolised through cytochrome P450 2D6 pathways; the major metabolites possess anti-arrhythmic activity. The cytochrome P450 CYP2D6 is coded by more than 70 alleles resulting in great genetic polymorphism of CYP2D6 isoenzymes, and up to 7% of Caucasian population are poor metabolisers. ⋯ No antidepressant or analgesic drugs were detected in toxicological screen. Propafenone overdose has been reported to be associated with features of severe cardiovascular and CNS toxicity. Aggressive treatment, meticulous monitoring and supportive care was associated with a good outcome in this case.
