Patient leaflet - ERLOTINIB ZENTIVA 25 MG FILM-COATED TABLETS
1. what erlotinib is and what it is used for
Erlotinib Zentiva contains the active substance erlotinib and is a medicine used to treat cancer by preventing the activity of a protein called epidermal growth factor receptor (EGFR). This protein is known to be involved in the growth and spread of cancer cells.
Erlotinib is indicated for adults. This medicine can be prescribed to you if you have non-small cell lung cancer at an advanced stage. It can be prescribed as initial therapy or as therapy if your disease remains largely unchanged after initial chemotherapy, provided your cancer cells have specific EGFR mutations. It can also be prescribed if previous chemotherapy has not helped to stop your disease.
This medicine can also be prescribed to you in combination with another treatment called gemcitabine if you have cancer of the pancreas at a metastatic stage.
2. what you need to know before you take erlotinib

- are allergic to erlotinib or any of the ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor before using Erlotinib if you:
