My father was diagnosed as advanced NSCLS. He is 74 years old asian man. He was smoking more than 20 years. He gave up smoking in 2009. Currently he has a tumor (6cm) on his left lung and a tumor (1.5cm) in brain. He has been taking Iressa for 3 weeks and develop few rush on his face. Should he try to increase the dose of Iressa? Any successful case? Is there any harmful by increaseing the dose?

Hallo again, waterspring. May I ask, did you decide to use Iressa from AstraZeneca or the Geftinat generic alternative we discussed on your earlier thread?

My understanding is that if the Iressa is going to work for your father, it will work at the standard dose. Standard doses are based on what patients have been able to tolerate in clinical trials, and increasing it could make your father ill. One of the doctors will be able to explain this better than I can. I really hope the Iressa works well for your father. Best wishes.

Thanks Certain spring. My sisters and I decided to use Iressa from Astrazeneca for the first couple of months, then transfer to Geftinat Generic alternative. Because my sister learned that other patients (1 or 2) buy the Geftinat Generic alternative from internet (alternative one, price is less 1/10 than Iressa from Astrazeneca ) and it works well (She almost talked with every patient/ patient's relative she could met in hospital. And in our culture, most of time people do not mind to talk the topic). We are discussing how to avoid buying the fake drug.

Like certain spring said iressa is prescribed at a dose that is considered to the highest effective dose. While the link below is about the opposite of your question I think it will help you understand the idea.

There is no convincing evidence that patients do clearly better with a higher dose of Iressa (gefitinib). In fact, the current standard dose of 250 mg is the current standard dose because patients on 500 mg daily didn't do any better than the patients who were on 250 mg daily -- they just experienced more side effects.

Thanks, Dr. West
I do not ask my father to increase the dose of Iressa. I called my dad yesterday. He told me he developed some rash on his back. Hope he can benifit from the drug.
