I have completed a series of Erbitux, 7 weeks. However after the 2nd week I broke out in a severe pimple, acne rash all over my face. The doctor skipped the next visit and cut my doses in 1/2. Also put me on Doxyclcline, an antibiotic. Have just finished treatment and just a little of the acne is left. I don't know much about this new drug. If anyone does please contact me.
