How long does a panic attack last?

It depends. Honestly, my worst ones have lasted for hours where I depersonalize and get dizzy, sometimes even black out. But I've had other panic attacks (the shock ones caused by my phobias, more specifically) which last around twenty minutes. There isn't really a specific time that a panic attack lasts and as much as I hate to say this because I don't think it's too helpful, but it truly relies on the person, place, and trigger.

Panik attack can last from about a minute to 30 minutes or so. The main thing to remember is to breathe in and out and think about good things.

Personally, my severe ones can last for 1-5 hours. They come with chest pain, dry mouth, elevated pulse and blood pressure. In my case, it's severe enough that I go to the ER to make sure I'm not having a heart attack or some other cardiac event. Even when my mind is calm, one can be set off, sometimes by extreme work stress. For me it's more of a physical thing than cognitive as I usually clear my mind of whatever triggered it within a few minutes.

For me it depends where I am but they last anywhere from 10-20 minutes but I've had a fee that lasted 30 minutes

It varies for each person, I'd imagine. Mine used to come on suddenly and last for about 5 minutes or so-- not that I ever really timed them.

A panic attack, for me, lasts about 5-10 minutes. However, sometimes it feels like it's a lot longer.

Panic attacks usually last up to 10 minutes but can vary depending on how severe the panic attack is.

A panic attack will usually reach it's worst within ten minutes. This can depend on person to person but most panic attacks rarely last more than 20-30 minutes. A panic attack lasting over an hour is very unlikely.

Personally, mine have lasted between two and ten minutes. I have only had one that lasted longer than ten minutes.

Panic attacks typically don't last too long, although they can seem like they are lasting forever. For me, panic attacks usually last no longer than 10 to 20 minutes. When I am in the middle of one, sometimes it is helpful for me to remember that although it feels like it may never end, they don't exceed 20 minutes and that likely in just a couple minutes, I will feel better. It also helps me to think of a panic attack as a wave. It builds, it peaks, and then you come down. Once that initial peak has occurred, you begin to feel more at ease, and in control. Panic attacks are tricky - and everyone experiences them differently! There is no uniform answer to exactly how long a "normal" one can last, but it is comforting to know that they are a temporary condition. They always end.
