Introduction: Amphetamine intoxication is a new life threatening poisoning among children. This study was designed to evaluate the clinical characteristics, laboratory findings and outcomes of children younger than 13 years due to exposure to derivatives of amphetamines referred to Loghman Hakim hospital between 2010 and 2011.Materials & Methods: In this descriptive study, Children (lower than 13 years old) who poisoned with derivatives of amphetamines and referred to Loghman Hakim hospital between 2010 and 2011 were studied. Vital signs, neurologic, psychologic and gastrointestinal findings, laboratory results, electrocardiographic changes, and also their outcomes before discharge were gathered.Finding: Collectively, thirty children were studied. There found 96% agitation, 91%, repetitive movements, 69% insomnia, 60% logorrhea, 94% tachycardia, 84% midriasis, 81% increased deep tendon reflexes, 9% tachypnea, 9% seizures, and 3% hyperthermia. 31 patients (97%) needed intravenous benzodiazepines (diazepam or midazolam). Of them, 12 patients (37.5%) need to administer one dose of intravenous benzodiazepines, 9 cases (28%) required second dose of intravenous benzodiazepines, and 10 cases (31.3%) required repeated doses of intravenous benzodiazepines or benzodiazepine infusion or intravenous use of haloperidol.Discussion & Conclusions: Symptoms and signs of poisoning with amphetamines may be mistaken with meningitis and brain hemorrhage. Hence, knowing the signs and symptoms of this type of poisoning can be treated early to prevent its dangerous side effects.
