Safety of non-therapeutic atomoxetine exposures - a national poison data system study

AIMS This study's objective is to assess the safety of non-therapeutic atomoxetine exposures reported to the US National Poison Database System (NPDS). METHODS This is a retrospective database study of non-therapeutic single agent ingestions of atomoxetine in children and adults reported to the NPDS between 2002 and 2010. RESULTS A total of 20 032 atomoxetine exposures were reported during the study period, and 12 370 of these were single agent exposures. The median age was 9 years (interquartile range 3, 14), and 7380 were male (59.7%). Of the single agent exposures, 8813 (71.2%) were acute exposures, 3315 (26.8%) were acute-on-chronic, and 166 (1.3%) were chronic. In 10 608 (85.8%) cases, exposure was unintentional, in 1079 (8.7%) suicide attempts, and in 629 (5.1%) cases abuse. Of these cases, 3633 (29.4 %) were managed at health-care facilities. Acute-on-chronic exposure was associated with an increased risk of a suicidal reason for exposure compared with acute ingestions (odds ratio 1.44, 95% confidence interval 1.26-1.65). Most common clinical effects were drowsiness or lethargy (709 cases; 5.7%), tachycardia (555; 4.5%), and nausea (388; 3.1%). Major toxicity was observed in 21 cases (seizures in nine (42.9%), tachycardia in eight (38.1%), coma in six (28.6%), and ventricular dysrhythmia in one case (4.8%)). CONCLUSIONS Non-therapeutic atomoxetine exposures were largely safe, but seizures were rarely observed.

Teaching practice recommendations: prevention and screening

The aim of this article is to provide guidance to family doctors on how to tutor students about effective screening and primary prevention. Family doctors know their patients and adapt national and international guidelines to their specific context, risk profile, sex and age as well as to the prevalence of the disorders under consideration. Three cases are presented to illustrate guideline use according to the level of evidence (for a 19-year-old man, a 60-year-old woman, and an 80-year-old man). A particular strength of family medicine is that doctors see their patients over the years. Thus they can progressively go through the various prevention strategies, screening, counselling and immunisation, accompanying their patients with precious advice for their health throughout their lifetime.
