Xanax vs Ativan: Overview
Xanax (alprazolam) and Ativan (lorazepam) are both benzodiazepines prescribed for anxiety disorders and panic disorder. They work by enhancing the effect of GABA, the brain's primary inhibitory neurotransmitter, producing sedative, anxiolytic, and muscle-relaxant effects. Xanax acts faster (onset within 15-30 minutes) but has a shorter half-life (6-12 hours), making it commonly prescribed for acute panic attacks. Ativan has a slightly longer duration (10-20 hours) and is preferred in clinical settings for procedures, status epilepticus, and alcohol withdrawal. Both are Schedule IV controlled substances with significant potential for dependence and withdrawal — they should not be stopped abruptly after prolonged use. Both have generic versions available.

Key Differences
Which Should You Choose?
Both are short-term treatments for anxiety — neither should be used long-term due to dependence risk. Xanax is often preferred for acute panic attacks due to its rapid onset. Ativan is preferred in medical/clinical settings and for patients who need slightly longer duration. Long-term anxiety management should involve therapy (CBT) and/or SSRIs/SNRIs rather than benzodiazepines. Always work with your doctor to use these medications safely and for the shortest time necessary.
