The EGFR gene is responsible for the production of the EGFR proteins which tells cells to divide. This means that when there is a mutation in the gene, it can cause the function of the protein to change and promote further growth of cells, even in cancerous cells. The cancer drug is used in targeted therapy to target the mutated gene within the cancer cell and blocks it.

The recommended dosage is 80 mg, taken orally without food until toxicity or disease progression.

Common side effects include fatigue, dry skin, diarrhea and decreased appetite.
