PHESGO is supplied in sterile, preservative-free, single-dose vials for subcutaneous administration. Store PHESGO vials in the refrigerator at 2°C to 8°C (36°F to 46°F) in the original carton to protect from light, until time of use. Do not freeze.
To prevent medication errors, it is important to check the vial labels to ensure that the drug being prepared and administered is PHESGO and not IV PERJETA® (pertuzumab), or IV or subcutaneous trastuzumab.
Inspect the vial for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use vial if particulates or discoloration is present. The solution should be clear to opalescent, colorless to slightly brownish. Do not shake.
A syringe, a transfer needle, and an injection needle are needed to withdraw the PHESGO solution from the vial and inject it subcutaneously. PHESGO is compatible with stainless steel, polypropylene, polycarbonate, polyethylene, polyurethane, polyvinyl chloride, and fluorinated ethylene polypropylene.
If the syringe containing PHESGO is not used immediately, it can be stored in the refrigerator for up to 24 hours (2°C to 8°C, 36°F to 46°F) and at room temperature for up to 4 hours (20°C to 25°C, 68°F to 77°F). Avoid unnecessary storage.
