I was taking Brabio for just under 3 months. In that period I had 4 occasions were 3 ish hours after injecting I would get hot and cold chills and a bit of a fever that I would sit through for a couple of hours. The last time I injected I noticed that the injection was going in slower than usual and as soon as it was done I began to feel like my chest was closing up and I managed to go downstairs and alert my husband. My husband called the ambulance and while he waited I stopped breathing a few times and on one occasion he had to intervene and press on my chest. I had what appeared to be a severe allergic reaction. Wanted to ask has anyone else experienced this and what information have they been given? My MS nurses just said stop taking the meds which I had figured out myself, but little insight was given. I have to decide what I might want to take next, perhaps Tecfidera. The paperwork on this medication does indicate such severe allergic reactions and I am quite scared it will happen again.
