heya didnt see this, pm me if you like, though ill be honest, an older clinician would be better positioned to answer this well, so i would be calling a hospital and chatting to the guru in the pharmacy department. really i dont see many people who have shockingly bad sensitivities on a regular basis, and most of the people i work with advocate the "take the second dose, and if you feel an itch or any swelling in your throat, go to the emergency room straight away" approach...which isnt fantastic practice imo, but when youre overworked (and more importantly, just dont give a toss, you just wait for 5pm so that you go home) thats what gets done.
