Been on exemestane for a little over a year and no problems with liver values, all still in the normal range. However, I have had increased kidney values last 2 samples starting about 7 months into the exemestane. Just watching for now and seems stable and even a little reduced. However, may have to switch to letrozole soon as I can’t go without sleep and that’s a major side effect for me. Will have to see if all normalizes once off the exemestane.
