RT Journal A1 Koller E, Malozowski S, Doraiswamy P T1 ATypical antipsychotic drugs and hyperglycemia in adolescents JF JAMA JO JAMA YR 2001 FD November 28 VO 286 IS 20 SP 2547 OP 2548 DO 10.1001/jama.286.20.2542 UL http://dx.doi.org/10.1001/jama.286.20.2542 AB To the Editor: Hyperglycemia has been associated with the atypical antipsychotic agents clozapine and olanzapine,1 and a recent case report described diabetic ketoacidosis associated with olanzapine in a pediatric patient.2 To gain further insight into the association between hyperglycemia and these 2 drugs in the pediatric population, we queried the US Food and Drug Administration (FDA) MedWatch drug surveillance system to identify cases occurring in patients younger than 19 years.
