Ativan 1mg, also known as lorazepam, is a prescription medication used to manage anxiety. It belongs to the benzodiazepine class, which works by calming the brain and nerves. Ativan enhances the effects of a natural chemical called GABA in the brain, helping reduce excessive anxiety and promote relaxation. It's typically used for short-term relief due to the risk of dependence and should only be taken under a doctor’s supervision.
