My husband was on Iressa, 23rd-27th of this month, it tore him up - n+v, severe lower extemity edema, made him groggy and incoherent. He stopped taking it after five days, couldn't take it any more. He passed away 3 days later. The lung tumor was nearly gone, it was the met. to the liver that there was not a thing we could do about.
From what I researched on Iressa, it is only given after two other forms of chemotherapy have been used and failed. It doesn't seem to have much promise and after what happened when my husband took it, I truly think it is nothing more than one last bit of false hope they are trying to offer dieing cancer victims while they take one last dip into their insurance comapanies coffers.
I am truly sorry to bear such ugly tidings. You have no idea how much I wish I could say this drug works. I wanted it to work so bad. But it didn't, it made it worse in his case. I'd advise your loved one not to even take it if the cancer has ANY liver involvement.
We knew my husband did not have long, a few weeks, maybe a month. Thanks to Iressa, it was over within one week. Even a day is precious. To be robbed of even one is heart breaking. Let your loved one live out what time he/she has without more chemicals robbing their strength, mental acuity and dignity.
