Not a medical field student, here, and won't say the correct answer, just chiming in. Every time my mother went into anaphylactic shock (very regularly), paramedics would ignore her medical alert bracelet to give her one of the incorrect answers on here, before the correct on. Which she was very much allergic to- as was noted on her bracelet. I am also allergic to it, though not as severe. Tl;Dr check bracelets, allergies to that medication are becoming more common.
