3 weeks ago I started sulfasalazine and I have now come out in a rash. I phoned my GP surgery and was called back by a GP who said the rash is unlikely to be caused by the sulfasalazine and is more likely to to be caused by a viral illness. He said to make an appointment in a week if it doesn't clear up. Has anyone else has had experience of a rash caused by sulphasalazine? If so did it itch (mine doesn't) and what did it look like please?
