The U.S. FDA’s March 4, 2025, warning letter to Dexcom Inc. is a well-detailed but heavily redacted document explaining the agency’s misgivings about procedures such as monitoring of acetaminophen content in glucose test dishes.

The FDA reported March 25 that Smiths Medical Inc., is recalling a series of oral and nasal endotracheal tubes because the diameters of the tubes may present with “a smaller diameter than expected.”

The speculation as to the status of Michelle Tarver, the acting director of the U.S. FDA’s device center, is officially over despite disclaimers at. The outgoing director, Jeff Shuren, said Tarver “will make a great center director” in remarks during an Oct. 17 public appearance, thus cementing Tarver’s role at FDA.
