Once considered safe, the common anesthetic is now linked to a rise in fatal poisonings across outpatient and home settings.
Poisonings and deaths linked to the common local anesthetic lidocaine have nearly tripled in the United States over the past decade, with fatal overdoses increasingly occurring outside hospitals, where untrained staff administer the supposedly “safe” anesthetic, a new analysis shows.
Over-the-counter topical lidocaine products, which typically contain up to 4 percent to 5 percent lidocaine, are primarily used for temporary relief of pain, itching, and burning sensations. The pain reliever is available in various forms, including creams, ointments, gels, sprays, patches, and foaming soaps. However, in medical settings, it can pose risks that many people may not be aware of.
