I have been taking sulphasalazine 2 tablets twice daily for about 3 months now having failed two other DMARDS. I had a letter from my consultant saying that my white cell count was low and that I must get another blood test. I did this and then went on Hols. When I went to the chemist yesterday to pick up a prescription there was a blood form with it from my GP telling me to go for a blood test. Do I need to worry? I seem to have periods of feeling totally exhausted but what is new there? Despite the hair loss and a slightly upset stomach this is the first drug to have helped me. I can now walk again unaided and even did swimming on holiday. Any views/advice?
