On day 2, participants will be given Taxol again through a needle in a vein over 24 hours. Participants will receive the drugs Decadron (dexamethasone), Benadryl (diphenhydramine) and Tagamet (cimetidine) prior to Taxol treatment to prevent allergic reaction due to Taxol. Participants will be observed for 1 hour after starting Taxol for harmful side effects. If none occur, both Taxol and Herceptin can be given on the same day on subsequent courses. Taxol will be premedicated with the same drugs on subsequent courses.
