Yes, its the same as amifostine. I had shots through most of my treatment although I missed four days in a row when I had just had my seocnd chemo (couldn't deal with the nausea from the chemo and amifostine too), and then the last two weeks I switched to once every other day ebcause they made me very sick (until the amifostine totally wore off about 3 hours after) and I vomited almost every single time despite taking all sorts of anti-nausea meds. BI'm glad I did the shots as much as I could because every bit of saliva helps right now.

My view for a lomg time was that vomiting once a day was a harsh proce to pay for keeping some saliva for the rest of my life but I was willing to pay it, although there were those four days in a row when I reached a spot where I wasn't--then they talked me back into doing it every other day.
