Preparation of Parenteral Solution
Parenteral drug products should be SHAKEN WELL when reconstituted, and inspected visually for particulate
matter prior to administration. If particulate matter is evident in reconstituted fluids, the drug solutions should
be discarded.
When reconstituted or diluted according to the instructions below, Cefazolin for Injection is stable for 24 hours
at room temperature or for 10 days if stored under refrigeration (5°C or 41°F). Reconstituted solutions may
range in color from pale yellow to yellow without a change in potency.
Single-Dose Vials
For IM injection, IV direct (bolus) injection or IV infusion, reconstitute with Sterile Water for Injection
according to the following table. SHAKE WELL.
