Erlotinib Tablets 100mg & 150mg
Erlotinib Tablets 100mg and 150mg are prescription medicines used to treat certain types of cancer. They belong to a group of targeted therapies called EGFR (Epidermal Growth Factor Receptor) inhibitors, which work by blocking signals that help cancer cells grow and spread.
Erlotinib is commonly prescribed for EGFR mutation-positive Non-Small Cell Lung Cancer (NSCLC) and, in combination with gemcitabine, for advanced pancreatic cancer.
Uses of Erlotinib Tablets
Erlotinib Tablets are used for:
EGFR-positive Non-Small Cell Lung Cancer (NSCLC)

Advanced pancreatic cancer (with gemcitabine)
Your oncologist will determine whether Erlotinib is suitable based on your cancer type and test results.
