Many locations have moved to using either Epi-Pen or Epi-Pen Jr. for treatment of anaphylaxis to avoid administration errors. The Pediatric Section on Allergy and Immunology published comments in 2007 and addressed the issue by recommending Epi-Pen Jr for 10-25 kg and Epi Pen for greater than 25kg. (Pediatrics 2007;119;638) The use of Epi-Pen Jr in children less than 10kg is finessed in the article (many clinicians do it for safety reasons but the decision should be made on a case-by-case basis - whatever that means). My questions for the groups: Are you routinely using the autoinjectors for over 10kg What are you doing for less than 10kg?
