On October 13, 2021, the U.S. Food and Drug Administration (FDA) reported Teligent Pharma’s voluntary recall of five lots of lidocaine HCl topical solution 4% in a 50 ml screw cap glass bottle to the user level because the firm’s testing found it to be super potent based on an out-of-specification result obtained at the 18-month stability timepoint.
