Background: My first BC diagnosis was DCIS in 2005, followed by lumpectomy on right breast, chemo, radiation, Arimidex; DCIS recurrence in 2016, followed by DMX and tamoxifen; Stage IV diagnosis in 2019, and I've been on Ibrance and Faslodex for 2.5 years, with the original lesions gone and no more findings so far. My problem is the fatigue from Ibrance knocking out my blood counts. I took a few weeks off Ibrance this summer to allow me to travel. After 4 weeks off, I felt great, but then started over again and my blood counts immediately took a dive along with my energy. My oncologist recommends cutting back from 3 weeks on and 1 week off at 75 mg, to 2 weeks on and 2 weeks off, to give my blood a chance to recover and me a chance to regain some energy. He does not want me to reduce the dose by cutting the pills in half. Has anyone else reduced their 75 mg Ibrance cycle like this? Did you feel less fatigued? Most important, was there any recurrence? Thx for listening.
