I would be interested to learn from other members of the group about their experiences with Azathioprine. I was tried on Azathioprine twice and even with a very low dosage (5 mgs) I had a terrible reaction both times. I was violently sick, dizzy, shaking, feverish, came out in a rash and hence was taken off the drug. One of the annoying things I found is that before taking Azathioprine my specialist at that time did not give me any warning about how violently my system might react to it and yet once I did react badly to it he afterwards said that my response was quite common !!!!
Luckily with a new specialist I went on to have Rituximab treatment which has put me in remission now since August 2010 and for which I will be forever grateful.
Anyway would be interested to hear how others have reacted to Azathioprine.
