Up to 1 year's worth: Herceptin (trastuzumab) can be given together with initial chemotherapy for the first 4-6 months then subsequently by itself for a total of 1 year. If chemotherapy was given first without Herceptin (trastuzumab) then Herceptin (trastuzumab) can be given for a full year by itself. The usual cycle runs every 3 weeks (17-18 cycles in one full year).
