Hi there just wanted to wish you well with the Cytoxan. We had a couple of members here who took it to help with their lungs and it did. They didn't seem to have to many side effects either.
I too have serious lung issues with pericardial effusions, pleurisy, and severe scarring on the lining of my lungs and the pericardium of my heart. I was put on oxygen 7 years ago. I took cytoxan too, I was on the oral type for 9 months then did 6 months on the IV form.
I didn't have the results they were hoping for. However, my lupus is really bad and I have multiple issues with it. Since it's a once a month treatment it's not to bad. Make sure you drink lots of fluids to flush the medication out of your kidneys and bladder.
Take care and if you have any more questions please feel free to ask.
