Please post your two cents on Herceptin "side effects" real or perceived!

I never had a reaction to Herceptin but I did to Tykerb. Dr. Slamon was directing my treatment at that time. I broke out in hives all over my body after taking 1000 mg (4 pills) Tykerb for four days. Dr. Slamon immediately dropped the dosage to 750 mg (3 pills) Tykerb at bedtime and Herceptin every three weeks. I was on this from 2/2009-6/2012 until the cancer came back a second time. Now I am on Kadcyla which is a very difficult drug in my opinion.
