In the 6 years I have been taking Imuran, I have had maybe 4 infections requiring antibiotics. However, none of these were for infections caused by breaks or cuts in the skin. I am an active gardener and cook and have had my share of cuts caused by broken sticks or improper knife handling. Some have been pretty deep puncture wounds. I just keep the site clean and dressed and watch for signs of infection like any person should/would do.
I don't have statistics for you to detail infection risk while on low dose Imuran. And yes, 100 mg is considered low dose compared to what transplant individuals take. I will say that my GI and rheumy both told me that my immune system is OVERactive and that taking Imuran makes mine more like that of individuals without autoimmune disease. Not sure if this is true but I do think there is some validity to it. I have far FEWER infections since being on Imuran than I did prior. I used to routinely get infections on my fingers from breaks in the cuticles before I went on Imuran. That no longer happens. Perhaps it is coincidence.
You seem to be treating her cut appropriately. Just watch for signs of infection and if any occur, get her seen. Hope she has no scarring!
