Tykerb/ herception in stage 3a locally advanced patients

[Cat]

I am currently on tykerb and herceptin indefinately and so far have felt very good. I was nervous at first about all the warnings but it has been very tolerable. The first month I had some diarrhea but now only peeling nails and slow growing nails and hair (no one can verify this is from the herceptin and/or tykerb). My concern is that the first month I received the tykerb from my hospitals pharmacy before we found out my insurance required we use their mail order specialty pharmacy. I am concerned that the tykerb is made unstable by the temperature during transport and that is why my symptoms are decreased and maybe the strength of the dose has been affected.
