My oncologist switched me to Faslodex (Fuverstrant) after 2-1/2 years on Letrozole/Ibrance combo as my cancer antigen marker went up to 50.
So far some fatigue, some difficulty sleeping and occasional heat flush. What side effects have others had? I got my first injections, one in each butt cheek, this past Wednesday. Is it worse at first or are there more effects as drug accumulates in the system?
