A: Ativan (lorazepam) is a benzodiazepine drug that acts as an anxiolytic (anti-anxiety drug), amnesic, sedative/hypnotic, anticonvulsant, and muscle relaxant. It's used for the short-term treatment of anxiety, insomnia, acute seizures, and sedation of hospitalized or aggressive patients.hen you first start lorazepam, your doctor may slowly increase your dose to avoid side effects. The dose of lorazepam may be lower if you are elderly or debilitated. Take lorazepam with liquid such as a glass of water, with or without food.
