Thank you jeffrey for your input. This past wendesday i started my fifth week on tarceva 150mlg. I have experienced the rash on my face only. My skin is extremly dry, but i can't say it itches me. I am constantly moisturizing my skin to help with the dryness; and for some strange reason the right side of my body including my face, is dryer than the left side of my body. Today i noticed my fingertips are shriveled; like as if my hands have been in water for a long time. I will have a ct scan on the 14th of the month and meet with my dr. On the 16th to discuss if tarceva is working for me; and if i am to stay on it, or seek an alternative form of chemotherapy. I wish you well with your treatment.
