title: The adverse effects of mefloquine in deployed military personnel.
abstract: BACKGROUND
  Mefloquine (Lariam®) is an effective anti-malarial prescribed to over 35 million travellers world-wide as chemoprophylaxis. However, it has been the subject of increased scrutiny and media attention due to its association with significant neuropsychiatric adverse events. Anecdotal evidence suggests that patient trust in the drug is waning.
  
  
  METHODS
  A prospective questionnaire-based cohort study of 150 deployed military personnel prescribed mefloquine as anti-malaria chemoprophylaxis. The primary study objective was to assess the rate of adverse reactions. In addition, an audit of mefloquine prescriptions and subsequent patient follow-up was conducted.
  
  
  RESULTS
  Among a cohort of 111 individuals taking mefloquine, 54% reported at least one adverse effect and 13% required a change in prescription to a second-line anti-malarial, due to significant side-effects. All females prescribed mefloquine reported at least one adverse reaction. There were two cases of clinically significant adverse reactions.
  
  
  CONCLUSIONS
  There was a higher rate of adverse events reported amongst deployed military personnel than has been reported among civilian patients. This may be partly due to the stressful environment in which deployed personnel operate.
