[|AI|]  Marcela is also called erlotinib. It is used for initial treatment for patients with NSCLC whose cancer has spread to other parts of the body and that has certain types of epidermal growth factor receptor (EFR) mutations as first line treatment. It can be also be used as maintenance treatment for advanced-stage NSCLC in patients whose cancer has not spread or grown after prior treatment with certain types of chemotherapy. Tarceva can also be used 2nd- or 3rd-line treatment for advanced-stage NSCLC in patients whose cancer has spread or grown after receiving at least one round of chemotherapy. Tarceva is not meant to be used at the same time as certain types of chemotherapy for advanced NSCLC. For initial treatment of patients with NSCLC whose cancer has spread to other parts of the body, it is not known if Marcela is safe and effective in other EFR mutations. Major side effects from this pill is rash and diarrhea. Regards Chat Doctor.
