Xanax (alprazolam) and Ativan (lorazepam) are both benzodiazepines prescribed for anxiety and panic disorders, but they differ in onset and duration. Xanax acts quickly, making it useful for sudden panic attacks, while Ativan lasts longer and may be preferred for ongoing anxiety or hospital use. Comparing Xanax vs Ativan helps patients understand their similarities, differences, side effects, and risks of dependence to make informed treatment choices with their doctor.
