    Dosage

    Severe anaphylactic reaction
    IM epinephrine is the first line treatment (anterolateral part of the thigh), however use IV epinephrine in patients with circulatory collapse or those who deteriorate despite receiving two IM injections of epinephrine.

     

    • IM treatment
      Use undiluted solution (1 mg/ml = 1:1000) and a 1 ml syringe graduated in 0.01 ml:
      • Child under 6 years: 0.15 ml
      • Child from 6 to 12 years: 0.3 ml
      • Child over 12 years and adult: 0.5 ml

     

    In children, if 1 ml syringe is not available, use a diluted solution, i.e. add 1 mg EPN to 9 ml of 0.9% sodium chloride to obtain a 0.1 mg/ml solution (1:10 000):

    • Child under 6 years: 1.5 ml
    • Child from 6 to 12 years: 3 ml

     

    Repeat after 5 minutes if there is no clinical improvement.

     

    • IV treatment
      Use a diluted solution, i.e. add 1 mg EPN to 9 ml of 0.9% sodium chloride to obtain a 0.1 mg/ml solution (1:10 000):
      • Child: 0.1 ml/kg (0.01 mg/kg) administered over several minutes
