Ativan (lorazepam) is a benzodiazepine medication that can be habit-forming, meaning that it can lead to addiction with prolonged use. The exact duration of use before addiction can vary depending on the individual and their specific circumstances. It is generally recommended that Ativan be used for short periods, usually no longer than two to four weeks, to avoid the risk of addiction. However, some individuals may develop dependence and addiction after even shorter periods of use. It is important to always use Ativan as directed by a medical professional and to speak with a healthcare provider if there are concerns about dependence or addiction.
