What is the best benzo for panic attacks?

Benzodiazepines are definitely not a wise choice for long-term care. Xanax works quickly. Benzodiazepines act fast and relieve your immediate symptoms, but they are very short lasting. Therefore, a plan should be made long term for a treatment plan other than the benzodiazepines.

Short Answer: Xanax (Alprazolam) - Feel free to read below on more info regarding this topic.
Everyone reacts differently to benzodiazepines. However, I'll insert some of the best Benzodiazepines that work therapeutically at recommended doses. For the treatment of the onset of a panic attack: Short acting benzodiazepines: Alprazolam (Xanax) 0.5-1 MG, Lorazepam (Ativan) 1 MG, Diazepam (Valium) 5-10 MG. Of those 3 I recommend a low dose of Xanax 0.5 MG. Within 10-15 Minutes of taking it via oral administration the panic attack will fade away. This is coming from someone who's tried the 3 benzos named above, and takes Xanax 1 MG 3 times daily since 2011.

If you are having panic attacks, You could have panic disorder. Which is something I wouldn't wish on my worst enemy. As I have it and struggled with it daily until 2011 when I found a doctor who didn't believe in writing Prozac, Paxil, Zoloft, Etc. As SSRI's are anti depressants and the black box warning lists of side effects are disturbing.
Long acting Benzodiazepines are much more effective and are less prone to causing dependence, withdrawal, and misuse. Clonazepam 1 MG (Klonopin) 3 times daily is what I take for my Panic disorder, along with Xanax 1 MG. Both are prescribed for different diagnosis. As I have GAD, PTSD, Panic Disorder and agoraphobia. I would say Klonopin is much more effective in preventing a Panic attack from coming on since it is long acting (one dose lasts 8-12 hours, with Xanax one dose only lasts up to 3-4). Klonopin just isn't good for stopping a panic attack because it takes 30-90 minutes to feel the effects of Klonopin.
