A prefilled syringe is a convenient primary packaging option for delivery of parenteral medication.

The packaging option is easy to carry and ready to administer without the need to dilute before injecting. Medications filled into vials require preparing the vial by sanitizing with an alcohol swab and using good aseptic technique to remove the medication from the vial. The reduction in steps required for syringe filling can reduce the risk of contamination versus a vial.

Convenience, product differentiation, and less waste are great reasons for developing a product in a prefilled syringe. This document describes the options available for prefilled syringes and provides some considerations for developing and manufacturing the product.
