I want to clarify the reconstitution of Herceptin since I have mine reconstituted with sterile water. Because of this I must have my Herceptin every 3 weeks since they would have to discard the unused portion since they receivce the Herceptin powder in a 3 weeks dose. If you can get your insurance company to pay for the reconstitution with sterile water on a weely basis more power to you -- my insurance company wouldn't authorize it as it meant money going down the drain. I also recevie my Herceptin with a bag of saline water on the side.

This infomration is directly from the Boxed warning:

The doctor's office recives the Herceptin in powder form. Each vial of Herceptin should be reconstituted with 20 mL of BWFI, USP, 1.1% benzyl alcohol preserved, as supplied, to yield a multi‑dose solution containing 21 mg/mL Trastuzumab. The reconstituted preparation results in a colorless to pale yellow transparent solution. Parenteral drug products should be inspected visually for particulates and discoloration prior to administration. Reconstituted Herceptin must be discarded after 28 days.

Use of diluents other than BWFI should be avoided unless contraindicated. For patients with known hypersensitivity to benzyl alcohol, Herceptin must be reconstituted with Sterile Water for Injection; discard any unused portion

I hope this information helps.
