Hi Clammy ~~ I went through several rounds of Velcade treatment until the side effects became too much and I had to stop. One of the main problems was the nausea and vomiting, lack of appitite and the loss of 50kg. The other problem was a horrible headache - I called it the 'mother of all headaches' which hospitalised me for a week while they tried to figure out what was wrong. I never had the bowel problem, however I did become extremely constipated and needed professional help to clear that up!!
On the positive side, my paraprotein level dropped dramatically while I was on the Velcade so that was really good. Unfortunately the side effects became more and more serious and I had to stop - being hospitalised for a month and spending another month in hospice because most people thought I was going to die. I was taken off of everything for 3 months, then I started on Revlimid. Revlimid has been my saviour for the past 18months. No side effects and the paraprotein is lower than it has ever been since my initial diagnosis!!
I guess my message is, hang in there. If Velcade causes too many problems for your mom, there are other things that she can try. Because myeloma is such an individual disease it may take a while to find the medication that works best for each person. From what I've read here on this site, she is in a State where there are good myeloma facilities. Best wishes to you both, Cath
