After being on Ibrance/Femara for the past 6 months, have now developed inflammatory pneumonitis and was taken off the drug this past month to see if inflammation clears up. This is my 4th round of breast cancer over 20 years and went metastatic 2 years ago. Had previously been on Faslodex injections which worked for 18 months. Have mets to lungs, chest wall, and lymph nodes. Anybody else having respiratory problems while on Ibrance?
