title: Olanzapine: review of safety 2008.
abstract: BACKGROUND
  Olanzapine is a second-generation antipsychotic approved for the treatment of schizophrenia, bipolar mania and associated agitation.
  
  
  OBJECTIVE
  To assess the safety profile of olanzapine, including its propensity to be associated with weight gain, diabetes mellitus and dyslipidemias.
  
  
  METHODS
  Review of English-language reports located through PubMed and information available on regulatory agency websites.
  
  
  CONCLUSIONS
  The use of olanzapine can pose a therapeutic dilemma in that on one hand, a number of large scale studies have found effectiveness advantages for olanzapine in comparison to other first-line second-generation medications. On the other hand, olanzapine is associated with substantial weight gain and the development of dyslipidemia. Regarding other important safety concerns, olanzapine has a favorable profile in terms of extra-pyramidal side effects and is also relatively prolactin-sparing. The effectiveness benefits may outweigh the risks, particularly in patients with low baseline risk for metabolic syndrome but monitoring for untoward metabolic effects crucial. Switch-or-stay and other intervention decisions need to be made early before substantial weight gain has occurred.
