Your oncologist should know the answer to your question. If he or she doesn't return your call tell your surgeon you are taking Tykerb and that some antibiotics cannot be used with it. Your surgeon should be aware of this problem. Your surgeon may be able to look it up in a drug reference. You should also ask your surgeon talk with your oncologist about this topic before the surgery.
