Evidence indicates that long-term sedatives and benzodiazepines are not effective treatments for acute suicidality and are instead frequently associated with an increased risk of suicidal ideation and self-injurious behaviors.
The retrieved literature contains no evidence that long-term sedatives are effective for acute suicidality; rather, studies such as FAERS disproportionality analyses link sedative-hypnotics and benzodiazepines to heightened risks of suicidal ideation and self-injurious behavior. Therefore, the claim is refuted by the available data.
