Here is an interesting article on the Tarceva "rash":

I was diagnosed with Stage IV NSCLC on 5/19/05 - I also have the EGFR mutation. I have been on Tarceva for 4 months - I have had 2 scans to check the result - the first scan showed my lung tumor shrank by 15%; the last scan showed that the lung tumor (as well as mets to my rib, spine and brain) stabilized.
I have an acne-like rash that migrates - one week it will be really intense on my face, then it will move to my arms and upper chest, then it will move to my lower legs and toes.... and then back again. My skin is very dry as well. I have tried over 15 different moisturizers and found that Aveeno Daily Moisturizer is the BEST! I also use Aquafor for my nose when it is really dry and flaky, but Aquafor is very greasy... I use Ocean Spray for my nose because my nasal passages are also dried out - so much so that I am getting bloody scabs (yuck!).
I am also experiencing hair loss - not in clumps, just lots of strands at a time. I have noticed that the hair falls out easily from those areas with the rash outbreak - such as my temple area. I have diarreha on occasion - but it usually comes and goes quickly (no pun intended!), so I do not use Immodium.
I am experiencing fatigue - I initially reduced my work schedule to 6 hours a day, 5 days a week. When I was completely exhausted by Thursday and had difficulty staying at work the entire day, I further reduced my work schedule by taking Wednesdays off. The extra rest in the middle of the week helps keep me going....
I did experience a period of loss of appetite, especially at dinner time, for a couple of weeks. I tried to make up the calories at breakfast and lunch. My appetite seems to be back to normal now.
I hope this information helps. Take care! - Kim
