I am on chemo vacation! 23 mo. On Ibrance/Letrozole combo for Stage IV mbc to lymph nodes, lungs. I still take 2.5 mg of letrozole daily My counts are normal but I had a severe Rash & frequent heavy fatigue episodes. My dosage was 75mg. How long could I be off before restarting Ibrance? I'm hoping to stay off for 2 to 3 months to feel good for awhile. Anyone else take a break from Ibrance for a month or more than resume to their daily dosage?
