Teligent Pharma issued a recall for two lots of Lidocaine HCl topical solution USP 4% 50ml due to super potency. Lidocaine is used as a local anesthetic, but an increased lidocaine dose could lead to systemic toxicity depending on the duration of treatment and the specific patient. This can result in central nervous system reactions such as hypotension and cardiovascular collapse, along with severe morbidity and even death.
