I have been by my doctor about three new meds,and would like to know anyone has experience with the following,cell cept,immuran and cytoxan. I am a 25 years old female diagnosed with S.L.E.(nephritis proliferive glumoritis)about 17years ago. Current therapy as of know is predisone along with plaquneil. Current therrapy is not as effective as the doctor would like it to be.Doctor is suggesting an additional drug like cellcept. My major concern is the possibility of getting cancer as a severe side effect.
