What is Iressa?

Iressa is an FDA (U.S. Food and Drug Administration) approved medication manufactured by AstraZeneca for cancer treatment.

Iressa is a tyrosine kinase inhibitor used for the first-line treatment of patients with metastatic non-small cell lung cancer (metastatic NSCLC) whose tumors have epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 substitution mutations as detected by an FDA-approved test. EGFR is overexpressed in the cells of certain types of human carcinomas – for example in lung and breast cancers.

The safety and efficacy of Iressa have not been established in patients whose tumors have EGFR mutations other than exon 19 deletions or exon 21 substitution mutations.

What doses of Iressa are available?

Iressa is available in tablet form, in the following doses: 250 mg.

The recommended dose is Iressa 250 mg tablet orally, once daily with or without food, until disease progression or unacceptable toxicity. Your healthcare provider will do blood tests to check your liver function during your treatment with IRESSA.

If you miss a dose take the missed dose as soon as you remember. Skip the missed dose if your next dose is less than 12 hours away. Do not take extra medicine to make up for the missed dose.

Always speak with your healthcare provider about any changes to your dose so they can monitor and evaluate your condition.
