Hi Mickyboy75 sorry I am not on exactly same meds I am on Ribociclib which is similar.  I am on cycle 6 now.  For the first five cycles I had the worst rash ever on my arms. legs stomach basically everwhere.  I have never known itching like it I scratched myself until I bled.  Oncologist said we could reduce the dose of Ribociclib but I wanted to try and stick it out.  I found piriton helped a little.  Now on my sixth cycle it has not come back.  Maybe you could talk to oncologist about reducing your dose.

Doctors said could be meds caused flare up slowly going now been using wynzora cream works well and epidermis cream overnight good but sow sticky have to keep duvet away from area, am of meds for 2 weeks oncologist said and blood test as my kidneys not good, and taste buds have gone, good luck with your recovery mick
