For how long can benzodiazepines be used before REM rebound occurs?

Benzodiazepines are often prescribed for the short-term management of anxiety, insomnia, and other conditions due to their sedative and anxiolytic properties. However, prolonged use can lead to certain side effects, one of which is REM rebound.

REM rebound refers to an increase in the duration and intensity of REM sleep that occurs after the withdrawal of benzodiazepines. This phenomenon typically occurs after a sustained period of use, as the drug suppresses REM sleep. Research indicates that REM sleep suppression can start to manifest after about one to two weeks of benzodiazepine use; however, significant REM rebound is more commonly associated with longer-term use of three to four weeks.

This timeline is crucial as it helps healthcare professionals consider the risks associated with chronic benzodiazepine use, particularly when developing treatment plans for patients. Monitoring and managing the duration of benzodiazepine therapy are therefore key in preventing or mitigating withdrawal effects, including REM rebound.
