For some reason I can't respond to discussions but can start my own.
I have commented on my rashes while on all the major TKI's so feel like the accidental Guinea pig. I just came off four months of Prednisone treatment while both on & off TKI's. So this would be strictly up to your onc.
The benefit of not taking the TKI would be you are eliminating the probable cause of the rash while treating the symptoms with Prednisone.
My end result is that I'm taking just 20mg Sprycel 3 times/week. Hopefully this will contain the CML and lessen the side effects.
By the by......Prednisone greatly increases you appetite so be prepared.
By the by....yes has been successful in getting rid of the rash
