hives herceptin

[donna77]

I have just had 2 of my 18 doses of herceptin and I am experiencing hives on my lower back. The oncologist's PA saw me on Monday and said that a rash is a very rare side effect of herceptin. He put me one a short course of steroids-but the hives are not disappearing. He said it definitely was not shingles but hives. I am seeing the Dr. for this tomorrow. Has anyone else experienced hives with this drug? Would this cause them to discontinue the herceptin? Thanks
