Ativan (generic name: lorazepam) is a prescription medication that belongs to the class of drugs known as benzodiazepines. It is commonly used to treat anxiety disorders, insomnia, and seizure disorders. Ativan works by enhancing the effects of GABA, a neurotransmitter that inhibits activity in the brain, producing a calming effect. This helps to reduce anxiety, induce sleep, and prevent seizures. Ativan is often prescribed for the short-term relief of severe anxiety and panic attacks. Ativan is used in emergency settings to control status epilepticus, a severe and prolonged seizure.
