Avastin and Oral Cytoxan side effects ?

New to this site and I posted this in another discussion. I was dx 8/2006. Since then 9 surgeries including initial debulking, bowel, spleen removal and removal of reacurring tumors and 35 chemo treatments (all kinds). I was on Avastin and taxotere and my oncologist is switching me to Avastin (every 3 weeks) and oral Cytoxan (50mg). I was able to tolerate the Avastin quite well with increased blood pressure. I'm curious about the typycal side effects of the oral Cytoxan. So far it looks like the pill is very tolerable. CA125 is always below 15 so not a great marker for me. CT/PET is my doctors greatest tool to help him stay on top of this mess!
