Intense fear can feel physically dangerous
Panic Attacks: Signs and What to Do
A panic attack is a sudden wave of intense fear or discomfort with strong physical symptoms. It is frightening, but support and effective treatment are available.
Chest pain, fainting, severe breathing difficulty, a first unusual episode, or symptoms after illness or substance use need medical assessment—do not assume they are panic.
Common features
- Racing or pounding heartbeat, sweating, shaking, chills or hot flushes
- Shortness of breath, tightness in the chest, choking sensation, nausea or dizziness
- Feeling unreal, detached, out of control, or afraid of dying
- Symptoms that rise quickly and then gradually ease
Only a qualified professional can assess whether symptoms are due to panic, another mental health condition, a medicine, substance use, or a physical illness.
During an episode
- Move to a quieter, safer place when possible and loosen restrictive clothing
- Breathe gently and slowly; focus on a longer, comfortable exhale rather than forcing deep breaths
- Name a few things you can see, hear and feel to reconnect with the present moment
- Remind the person that the wave will pass; stay calm and avoid criticism or crowding
- Seek urgent medical help for severe or unfamiliar physical symptoms
When repeated attacks need help
Repeated unexpected attacks, a month or more of fear about another attack, or avoiding travel, crowds, work or school may indicate panic disorder. A clinician may check for physical causes and discuss psychological treatment, medication, or both.
- Track when episodes happen, how long they last, sleep, caffeine, alcohol or drug use, and what you were doing
- Keep regular sleep and meals and reduce excessive caffeine or stimulant use
- Do not start, stop or borrow medication without a prescriber
Emergency warning signs
Call 112 or go to emergency care for loss of consciousness, severe chest pain or breathing difficulty, seizure, overdose, serious self-harm risk, or any rapidly worsening medical concern.
