Hi Matilda
I've been on Tarceva for one yr now. I have stage 4 right NSCLC that is EGFR +. The most common and desired side effect is skin rash. Yes, desired!
The rash is a good indicator it is working. Also, some loose stool or diarrhea is fairly common. But, you can manage this with Imodium and you learn what foods cause problems. My last scans showed the one remaining lung tumor is about the size of a pea and bones appear healed. Tarceva, for some is a wonder drug. Good luck:)
