IRESSA Oral Uses
This medication is used alone to treat lung cancer after other cancer chemotherapy treatments have not been successful. It is a cancer chemotherapy drug which works by blocking a certain protein (an enzyme called tyrosine kinase) which may help cancer grow and spread.
How To Use IRESSA Oral
Take gefitinib by mouth once daily, with or without food, or as directed.
Medications which reduce or completely block stomach acid (e.g., proton pump inhibitors/PPIs, H2 blockers, antacids) may decrease the absorption of gefitinib. This could decrease the effectiveness of gefitinib. Consult your doctor or pharmacist if you are taking any of these medications.
Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day.
