Baxter International Inc. has recalled four lots of intravenous solutions due to the potential for leaking containers and particulate matter, the Food and Drug Administration announced this week. Hospital and other customers should not use the products and should return them to Baxter for credit, the company said, noting that unaffected lots of the products are available for replacement. The recall includes two lots of 0.9% sodium chloride injection distributed between Feb. 22 and Dec. 28, 2015, used as a source of water and electrolytes and to reconstitute powdered drug product; one lot of metronidazole injection distributed between Oct. 9, 2015 and Jan. 18, 2016, used to treat certain serious bacterial infections; and one lot of Clinimix E sulfite-free injections distributed between May 29 and Dec. 3, 2015, used in nutrition regimens.
