The U.S. Food and Drug Administration (FDA) is aware the United States is experiencing interruptions in the supply of prefilled 0.9% sodium chloride (saline) intravenous (IV) lock/ flush syringes. Prefilled 0.9% sodium chloride IV lock/ flush syringes are in shortage because of an increase in demand during the COVID-19 public health emergency, as well as recent vendor supply chain challenges, including the permanent discontinuance of certain prefilled saline lock/ flush syringes.
