Is Lorazepam a good sleep aid?
Taken at night, benzodiazepines can lead to next-day drowsiness and sedation. These drugs last longer and so may help a person stay asleep through the night. In practice, many of the benzodiazepines used for treating anxiety — such as lorazepam (Ativan) and alprazolam (Xanax) — are also used to induce sleep.
How long does lorazepam stay active in your system?
The average half-life for Ativan is approximately 12 hours. This means that after taking your last dose, it may take around 2.75 days for the drug to be fully eliminated from your system. The active metabolite of lorazepam glucuronide has a longer half life of 18 hours.
