"Lorazepam, sold under the brand name Ativan among others, is a benzodiazepine medication often used to treat anxiety disorders. Lorazepam reduces anxiety, interferes with new memory formation, reduces agitation, induces sleep, treats seizures, treats nausea and vomiting, and relaxes muscles.
Lorazepam is used for the short-term treatment of anxiety, insomnia, acute seizures including status epilepticus, and sedation of hospitalized patients, as well as sedation of aggressive patients. Due to tolerance and dependence, lorazepam is recommended for short-term use, up to two to four weeks only."
