Dot my eldest son had an allergic reaction to Flagyl when he was about 18, after taking same he went into anaphylactic shock, couldn’t breathe it was 5.30am he was pressing his buzzer no nurse arrived so he thru his stainless dish down onto the floor & out the door, attention at last, he was in the Private hospital, fortunately an anaesthetist was arriving for his scheduled operations, he treated him & he was rushed to the local state hospital where he spent several days, it was a scary experience for him & us when we received the phone call to say that he was being transferred.
Wow, after your experience no more dye injections for CT scans, definitely allergic to same
