I had to use my son's epipen on him for the first time recently. It was pretty nerve racking actually but on reflection I was pretty impressed at how I managed to take control and handle is reaction - he is allergic to wheat. The ambulance crew got there pretty promptly and gave IM steroids and more piriton again IM and we spent some time in hospital. What worries me is that I was hoping he would grow out of it however the quantity he consumed was pretty small and the reaction was a full on anaphylactic reaction 
Anyway, we are off on hols in a couple of weeks. It has just dawned on me that the epipen has to be kept below 24 degrees. We are going to hot climes! He is 14.2kg and Dr reluctant to prescribe Jext pen until he is 15kg. Any advice?
