Treats certain types of non-small cell lung cancer (particularly those with EGFR mutations) and pancreatic cancer (typically used in combination with other medications)
Erlotinib is a targeted therapy that reversibly binds to and blocks the EGFR tyrosine kinase, preventing signal transduction that cancer cells need for growth and survival
Common side effects include skin rash and diarrhea. Regular monitoring of liver function may be needed. Effectiveness depends on specific tumor characteristics including EGFR mutation status.
