Hi, I've been doing research on the Internet for my Mom who has lung cancer and is taking Tarceva. She's been taking it for about 8 months with great results. Unfortunately, she does have side effects - severe itchy-dry skin, severe diarreha with abdominal pains and fatigue. I've found two helpful websites besides this one that I thought I'd pass along in hopes that they'd help you also. For great information about skin care for those taking Tarceva:
