Herceptin Increasing Appetite?

[Esther]

I was on herceptin from Jan 04-April07, had a 5 month break to test out going on Tykerb and am now back on Herceptin.

When I was on Herceptin the first time, I gained weight during the time I was on it. Once off of it, I was able to begin losing the weight.

Now since my infusion 2 weeks ago, I am finding that I have a bigger appetite and am hungrier. Could it be the Herceptin?

Has anyone else had an increase in appetite from Herceptin?
