pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Iressa. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay.
