Effects of long-term benzodiazepine use Other concerns about the effects of long-term benzodiazepine use, in some, include dose escalation, benzodiazepine abuse, tolerance and benzodiazepine dependence and benzodiazepine withdrawal problems. Both physiological tolerance and dependence can lead to a worsening of the adverse effects of benzodiazepines. Increased risk of death has been associated with long-term use of benzodiazepines in several studies, however, other studies have not found increased mortality.
