Most panic attacks last for between 5 and 20 minutes. They can come on very quickly, and your symptoms will usually peak within 10 minutes. Sometimes you might experience symptoms of a panic attack which last for up to an hour.
Although many people have only isolated panic attacks, others suffer from recurring attacks, which is a symptom of panic disorder. This disorder is fairly common; 2.7 percent of Americans 18 and up have it, which makes it more common than bipolar disorder, schizophrenia and obsessive compulsive disorder [source: NIMH]. Panic attacks can last anywhere from a few minutes to a half-hour, and they're gravely frightening and confusing for the victim. If left untreated, recurring episodes can lead to agoraphobia, where the fear of having an attack becomes so intense that the sufferer avoids all public places.
