Hi ! My husband is on erlotinib (common name Tarceva) in his case it is given the tablet once a day. He is doing pretty well on it. He also gets gemzar by infusion once a week. The worst side effect he is getting that is a result of the Tarceva is a rash. Not anything to difficult to deal with, mostly face and scalp. The doc gave him some acne type meds for his face and he uses a shampoo called T-gel that helps his scalp.
My husband is on his second round of gemzar after a two-week break, but he stayed on the tarceva through the break. So far he has had no tumor growth!
I hope this info helps you.
