What side effects do people have on sulfasalazine? I have been started on it as I am allergic to methotrexate. I've only taken two tablets but I feel strange. A sort of feeling that I'm about to stop breathing and pass out. I was tried on it once before and the same thing happened but it was put down to the methotrexate.
Am I making this up or has any else had this. It's a really strange feeling.
