I don't think anyone really knows the answer to your question and that's the problem with all cancers and chemos and meds and the list goes on. But. . . my philosophy was to change it up a little bit each time I went in for herceptin. That way, if I was inhibiting it, it wouldn't be inhibitited every time! LOL (for example, if I drank coffee before an infusion, the next week, I made sure I had NO coffee the day or 2 beforehand) I know it sounds crazy, but I just was so scared about the same thing you asked about!!!
