Why is it prescribed?

Erlotinib is used for treating advanced or metastic non-small cell lung cancer. It is used when:

  • at least one regimen of chemotherapy has not been effective
  • 4 cycles of chemotherapy have stabilized the cancer growth. Erlotinib may be used for maintenance therapy
  • the patient has a confirmed activating mutation of the epidermal growth factor receptor tyrosine kinase.


Erlotinib is used to treat advanced non-small cell lung cancer that has not responded to chemotherapy and has tested positive for the activating mutation of the epidermal growth factor receptor tyrosine kinase.
Erlotinib targets lung cancer cells and may help to stop them from multiplying and growing.
Take this medication on an empty stomach, at least one hour before or two hours after eating.
If you develop diarrhea, you may treat it with non-prescription loperamide tablets. It is also important to drink lots of water and other fluids to prevent dehydration from occurring.
