Lorazepam HF 2mg, Ativan, also known as Lorazepam, is a prescription medication belonging to the benzodiazepine class. It is primarily used to treat anxiety disorders, including anxiety attacks, panic disorder, and generalized anxiety disorder. Lorazepam works by enhancing the effects of a neurotransmitter called GABA in the brain, which helps to slow down brain activity and promote relaxation. It can also be used to treat insomnia, seizures, and muscle spasms. Ativan is available in various forms, including tablets, injectable solutions, and oral solutions, and its effects typically start within 15-30 minutes after administration. However, due to its potential for abuse and dependence, Ativan should only be used under the guidance of a healthcare professional and for a limited time period.
