  • Children over 30 kg bodyweight: The usual dose is 300 micrograms.

  • An initial dose should be administered as soon as symptoms of anaphylaxis are recognised. In the absence of clinical improvement or if deterioration occurs, a second injection with an additional Emerade may be administered 5 – 15 minutes after the first injection. It is recommended that the patients are prescribed two Emerade pens which they should carry at all times.
