CLYBL and toxic epidermal necrolysis: Compared with 1,4-benzodiazepines, such as diazepam and clonazepam, CLB shows an improved side effect profile and is associated with a lower incidence of nervous and skin system complications, such as Stevens–Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN); sedation and physical discomfort; and physical dependence [2,3,4].
