Preparation and Administration of Intra-Articular Suspension
Refer to the Instructions for Use for directions on the preparation and administration of ZILRETTA.
ZILRETTA is supplied as a single-dose kit containing a vial of ZILRETTA microsphere powder, a vial of sterile diluent, and a sterile vial adapter.
ZILRETTA must be prepared using the diluent supplied in the kit.
Preparation of ZILRETTA requires close attention to the Instructions for Use to ensure successful administration.
Use proper aseptic technique throughout the dose preparation and administration procedure.
ZILRETTA is a suspension product and it is normal for some residue to be left behind on the vial walls after withdrawing the contents.
Promptly inject ZILRETTA after preparation to avoid settling of the suspension. If needed, the ZILRETTA suspension can be stored in the vial for up to 4 hours at ambient conditions. Gently swirl the vial to resuspend any of the settled microspheres prior to preparing the syringe for injection.
The usual technique for intra-articular injection should be followed. Aspiration of synovial fluid may be performed based on clinical judgment prior to administration of ZILRETTA.
