I gained around 15-20 pounds while taking herceptin. I, too, have wondered why it hasn't been yet listed as a side effect. It seems on this site, there are many who have reported a weight gain with herceptin.

What convinces me that herceptin may cause weight gain, is when I read about the ladies who report a gain, and say they have "always been thin"..."never have had any issues with weight gain"...etc. and yet they gain weight on herceptin.

Not complaining, of course, because we know what a blessing the drug has been to many, but it would be beneficial to know this side effect; I kept telling my onc I was gaining weight, but yet eating the same as I had before; being real careful, etc. He sent me to an endrocrinologist to check out the thyroid as the numbers were a little high; he didn't want to give me meds; fine with me. My weight kept creeping up, up, up. After completing herceptin, the increases stopped.
