how long can a panic attack last

Most panic attacks are short, usually peaking within 10 minutes and ending within about 20–30 minutes, though the “shaky” after‑effects can linger for hours. In rarer cases, people may experience repeated or rolling panic attacks that make it feel like one long episode lasting several hours, but this is less common and often overlaps with ongoing high anxiety rather than a single classic panic attack.

Quick Scoop

• Typical duration :
  • Peak fear and physical symptoms usually hit within 5–10 minutes.

* Most single panic attacks are over in about 15–30 minutes.

• Longest they can feel :
  • Research and clinical descriptions often place a single panic attack at up to around 30 minutes, although some people report feeling in “attack mode” for hours.

* What lasts longer is usually a mix of repeated attacks plus lingering anxiety, not one continuous peak panic the whole time.

• After-effects :
  • Tiredness, shakiness, chest tightness, or feeling “on edge” can last for several hours after the main attack ends.

• Panic vs. anxiety attacks :
  • Panic attacks: sudden, intense, short-lived, usually 5–30 minutes.

* Anxiety attacks: often build more slowly and can last hours or even days, especially if the stressor continues.

When to seek urgent help

• Call emergency services or go to ER immediately if:
  • Chest pain, trouble breathing, or pain spreading to arm/jaw (could be heart-related).
  • Confusion, severe headache, loss of consciousness, or stroke-like symptoms.
• Reach out to a mental health professional soon if:
  • Attacks are frequent, last a long time, or you fear the next one so much you avoid normal activities.

If you’ve been feeling like your “panic attack” lasts for many hours or all day, that might be high, ongoing anxiety with spikes of panic—still very real and very treatable, but worth discussing with a professional.
