Hi Chris,
I have been taking Tarceva since April of this year with great success. I have had a severe rash through most of that time, only now is it subsiding. I have had the rash all over my body.
The worst of it now is on my scalp and I am having trouble with wearing shoes because of a very sore toe. All related to Tarceva so my onc tells me. My skin is dry and my hair, well that's just something else!!! LOL!! I also have the rash on my tongue, it just means I stay away from vinegar and salad dressings etc.
Hope this helps and all the best to you,
Sharon
