I am sorry to hear of your severe rxn to Tarceva. I have had a similar reaction, although perhaps not as severe. My face burned and was very inflamed and had the acne issues you mentioned too. I had a rash and acne on my back also. I saw a dermatologist and saw some relief with the items she gave me, but honestly, it took a few weeks to see the results. I was miserable for awhile there. I had days where I wished I could just peel my skin off and start over. I chose to stick with the Tarceva as I know if is working on the cancer cells. My first two CTs showed marked reduction in the size of the cells. I have been on Tarceva for a year now.
My fingertips (and my heels) cracked in the winter months where I had never had that problem before. I apply moisturizer every morning and night now. Make sure you use gentle products like Aveeno or Eucerin with no fragrances or dyes. You should use a mild soap for your hands and shower (like Dove).
I also lost most of my hair in a "shedding" way, not coming out in clumps, but still requiring me to get a wig and wear hats alot. It is slowly returning,but now it is no longer poker straight, but very curly (strange!). My fingernails and toe nails are very weak/thin. My eyelashes have gone very wild - crazy long and twisty - again , strange!
It is a rough road, but I do hope that your adverse reactions lessen enough for you to stay on the meds. You can make it through the problems, I'm sure of it. Don't lose hope!
Best Regards
Ann
