epipen
Actually the only mention of Epipen on the medical forms is to ask you if you carry one, and not to say that you can't carry one. Also I had my FI with the HEAD of recruitment, I explained my allergies to her, and she said that everything was fine.
Besides, the epipen for me is a simple precaution, I have never used it and I don't think I ever will, so a no-Epipen rule would be no problem.
