How to Stop a Panic Attack: 5-Step Crisis Protocol and the Ride-It-Out Method

DO THIS RIGHT NOW if you are having a panic attack

If you are in the middle of a panic attack, use this 5-step protocol right now. Do not finish reading first. Do it:

Sit and ground. Feet flat on the floor, hand on a chair or wall. Feel the ground. Lower yourself if you are dizzy. Stay where you are if safe.
Slow exhale longer than inhale. Inhale through your nose for a count of 4. Exhale through your mouth for a count of 6 to 8. Repeat 6 to 10 times. Slowly.
Name what is happening: "This is panic, not danger." Do not argue with the thoughts. Say it: "This is a panic attack. It will peak and pass. I am not in danger."
Stay where you are if you are safe; do not flee. Avoidance reinforces panic. The panic will peak and decline on its own. Leaving the situation teaches your brain to fear it.
Wait for the peak (about 10 minutes), then for full resolution (20 to 30 minutes total). Panic is time-limited. You will survive this. Adrenaline will deplete. The wave will pass.

GO TO THE ER NOW

If you are reading this with any of the following, call 911 (US) or 999 (UK) or 112 (EU) immediately. Do not wait:

Chest pain that is heavy, crushing, or radiating to your arm, jaw, or back
Severe shortness of breath at rest
Fainting or feeling like you will faint
Slurred speech, confusion, or difficulty speaking
First-ever episode of these symptoms (cannot assume it is panic without medical evaluation)

This guidance follows Mayo Clinic and American Heart Association protocols. A chest pain ER visit is the correct call, even if it turns out to be panic. Anxiety is a diagnosis of exclusion, meaning cardiac disease must be ruled out first. See PAG row 17 for full panic attack vs heart attack guidance.

Direct Answer: How to Stop a Panic Attack

To stop a panic attack, slow your breathing with longer exhales than inhales (inhale 4, exhale 6 to 8), ground your senses on the room around you, label what is happening as panic not danger, and do not flee the situation if you are safe. Most panic attacks peak within 10 minutes and resolve within 20 to 30 minutes. With practice of this protocol, you can shorten the peak and reduce its intensity. The key is learning to ride the wave instead of fighting it. Per Mayo Clinic and Craske (2009), the peak discomfort lasts about 5 to 20 minutes. Most attacks resolve within 30 minutes without intervention.

The Critical Paradigm Shift: Stopping vs Riding Out the Wave

This is the most important section of this post.

When a panic attack hits, your instinct is to make it stop the way you stop bleeding or a burning sensation. You think: "I must stop this NOW." You seek escape. You call an ambulance. You run. You fight the sensation.

This does not work.

A panic attack is not like stopping a nosebleed. You cannot will it away or force it to stop. The sensations have to peak and resolve. What you can do is shorten the peak duration, reduce its intensity, and prevent the reactive panic spiral (panic about the panic) that extends the episode.

This reframe is everything.

Per Craske (2008), panic attacks follow a natural curve: the sensations build, hit a peak (usually 5 to 20 minutes), and then decline. The peak is not indefinite. Your body will tire. Adrenaline will deplete. The sympathetic nervous system (fight-or-flight) will hand off to the parasympathetic nervous system (rest-and-digest).

Your job is not to stop the panic. Your job is to:

Stay safe. Do not drive recklessly. Do not jump out a window. Stay in a safe location.
Stop the reactive spiral. Do not panic about the panic ("Oh no, this is happening again! This is terrible! I cannot handle this!"). That amplifies the episode.
Activate the brake pedal (your parasympathetic nervous system) to speed up the natural resolution.
Learn by direct experience that panic peaks and passes. This is inhibitory learning, the foundation of cognitive behavioral therapy for panic (Barlow, 2002).

The Mastery of Anxiety and Panic program (Barlow & Craske, 2008) teaches exactly this: panic is a time-limited biological response. You do not stop it; you accept it, ride it, and learn it is not dangerous. Each time you do this, you train your brain that panic is survivable and not a sign of danger.

This is the shift from crisis mode to mastery.

The 5-Step Panic Protocol, Expanded

Use this whenever a panic attack starts or is in progress.

Step 1: Stop and Ground (The Body)

Your first instinct during panic is to move: to pace, to escape, to run. This feeds the panic. Instead, immediately find a safe place to sit or lean.

Sit on a chair, couch, or floor. Get your body supported.
Feel your feet on the floor or ground. Press them down. Feel the contact.
Lean your back against a wall or chair. Feel the pressure. Your body is supported and safe.
If you feel dizzy or faint, lower yourself to the floor or a cushion. Lying down is fine. The goal is to feel stable and grounded.
If you are able, tell someone you trust: "I am having a panic attack. I am safe. I need to breathe." Saying it out loud is grounding. You do not need to describe symptoms; just name it.
Do not flee. Do not leave the room, leave the store, or leave the situation if you are safe. Fleeing teaches your brain to fear the situation. Staying teaches your brain the situation is not actually dangerous.

This simple act of stopping and grounding signals safety to your nervous system and interrupts the fight-or-flight cascade.

Step 2: Breathing Reset (The Nervous System)

This is the most powerful intervention you can do in the moment.

Panic hyperventilation (rapid, shallow breathing) causes two things: (1) CO2 levels drop, which worsens dizziness, tingling, and derealization; and (2) your body interprets rapid breathing as continued danger, which feeds the panic loop.

The fix: slow, extended-exhale breathing activates your parasympathetic nervous system, the brake pedal of your body.

The technique:

Breathe in slowly through your nose for a count of 4.
Pause briefly (1 second).
Breathe out slowly through your mouth for a count of 6 to 8.
Pause briefly (1 second).
Repeat 6 to 10 times (about 2 to 3 minutes).

Critical: Do NOT take huge deep breaths. That is hyperventilation and makes panic worse. Slow and steady. If you feel lightheaded, you are breathing too fast. Slow down even more.

Why this works:

The extended exhale activates the vagus nerve, the main parasympathetic nerve. Vagal activation triggers a cascade: heart rate slows, blood pressure drops, stress hormones (cortisol, adrenaline) decline, and the amygdala (the alarm center) quiets. This is not placebo. Zaccaro et al. (2018) conducted a meta-analysis of breathing interventions and found that slow breathing with a longer exhale than inhale significantly reduces heart rate, blood pressure, and anxiety.

Also, the slower breathing corrects respiratory alkalosis (too much CO2 loss), which reduces the dizziness, tingling, and unreality that panic causes. Your body chemistry stabilizes.

Step 3: Label Without Judgment (The Mind)

During panic, your brain produces catastrophic thoughts: "I am dying. Something is terribly wrong. I cannot handle this. I am losing my mind."

These thoughts feel like facts in the moment. They are not. They are symptoms of panic.

You do not need to argue with them or convince yourself they are false. You need to label them and move on. This is called cognitive defusion (Craske, 2009).

What to say to yourself:

Pick one simple phrase and repeat it:

"This is panic. It is uncomfortable. It will not hurt me."

Or:

"This is a panic attack. My body is safe. The sensations will peak and pass."

Or:

"I am having panic. It is real discomfort, but it is not dangerous."

Repeat your phrase 5 times slowly while you are breathing and grounding. Do not try to feel calm. Do not try to convince yourself. Just say the words. The label itself reduces amygdala activity and prevents the catastrophic thought spiral from amplifying the panic.

Step 4: Stay Where You Are (Behavioral Anchor)

This is the hardest step and the most important for long-term recovery.

Every single time you escape from a panic situation by leaving, driving away, calling an ambulance unnecessarily, or asking someone to come rescue you, you teach your brain one thing: "Panic is dangerous. I need to escape."

This reinforces panic disorder. Your brain learns to fear the situation. Next time you approach it, panic anticipates the threat, and the loop repeats. This is avoidance conditioning, and it is the primary mechanism maintaining panic disorder (Barlow, 2002).

The alternative: Stay where you are (if safe).

If you are at work, stay at work. If you are in a store, stay in the store. If you are on public transit, stay on the transit. If you are driving (safe to do so), slow down and keep going.

This is hard. But it is the foundation of cognitive behavioral therapy for panic (CBT-Panic). By staying, you learn, in your body, that the situation is not actually dangerous and that panic is survivable. This is inhibitory learning, the most powerful tool for breaking panic disorder.

What if I am not safe? If you are dizzy while driving, pull over safely. If you are in a dangerous location, move to a safe location. Then use the 5-step protocol.

Step 5: Wait for Peak, Then Resolution (The Timeline)

Panic follows a timeline. Know it. Trust it.

Minutes 0-3: Panic onset. Adrenaline surge. Rapid breathing, racing heart, intense fear.
Minutes 3-10: Peak intensity. This is the worst part. The sensations are intense. The thoughts are catastrophic. Your body feels like it is failing. THIS PASSES.
Minutes 10-20: Decline phase. Adrenaline depletes. Your parasympathetic nervous system activates (especially if you are doing slow breathing and grounding). The intensity decreases.
Minutes 20-30: Resolution. Physical symptoms fade. Breathing normalizes. Thoughts quiet. You feel tired and shaky but safe.

Your job during peak (minutes 3-10) is to stay present and do the protocol. Do not panic about the panic. Do not think, "When will this end?" Do not check your watch obsessively. Just breathe, ground, label, and stay.

The peak will pass. It always does. It has never lasted forever for anyone, ever. Your body will run out of adrenaline. The wave will decline.

Track the timeline. Write down when it started, when it peaked, and when it fully resolved. This data is gold for therapy. It shows you that panic is time-limited and predictable.

Why Slowing Breathing Actually Works: The Physiology

Your vagus nerve is the main parasympathetic nerve, the brake pedal of your nervous system. It runs from your brain down to your heart, lungs, and gut. When you activate the vagus nerve, your nervous system shifts from fight-or-flight to rest-and-digest.

Slow breathing, especially with a longer exhale, directly stimulates the vagus nerve. Here is the cascade:

Extended exhale stimulates vagal afferents (signals traveling back to the brain).
Vagal activation slows the heart rate via the vagal brake mechanism (Laborde et al., 2018).
Parasympathetic activation reduces adrenaline and cortisol and increases acetylcholine, the calming neurotransmitter.
CO2 restoration corrects respiratory alkalosis, reducing dizziness and tingling.
Amygdala quieting: Slow breathing with vagal tone dampens amygdala hyperactivity and re-engages the prefrontal cortex (rational thinking).

This is not willpower. This is not positive thinking. This is physiology. The slow breathing literally changes your nervous system state.

Brown and Gerbarg (2012) and Zaccaro et al. (2018) have published extensively on this mechanism. The evidence is solid.

Common Mistakes That Worsen Panic

Hyperventilating to "get more air." Rapid, shallow breathing drops CO2, which worsens dizziness, tingling, and derealization. It also keeps the body in fight-or-flight mode. The fix: slow breathing with extended exhale, not fast deep breathing.

Fleeing the situation. Avoidance reinforces panic over time. Every escape teaches your brain to fear the situation. Stay where you are (if safe). This breaks the avoidance cycle. This is CBT for panic.

Reaching for a benzodiazepine (Xanax, Ativan) for every attack. Benzodiazepines work quickly and feel very effective. The problem: they carry risks of dependence, tolerance, cognitive impairment, and rebound anxiety. More critically, they interfere with the extinction learning (inhibitory learning) that happens in CBT for panic (Otto, 2010). If you use benzos, use them as prescribed, but pair them with therapy. Do not let benzos become your only tool.

Reassurance loops (calling a partner, Googling symptoms). Asking for reassurance ("Am I okay? Is this a heart attack?") provides short-term relief. The problem: it reinforces the cycle. Next time panic rises, you seek reassurance again. This is the opposite of learning that you can tolerate anxiety and that panic is not dangerous. Practice sitting with the uncertainty. Ride the wave. Learn by direct experience that it passes.

Drinking alcohol or caffeine to manage panic. Caffeine increases heart rate and anxiety. Alcohol is a depressant that makes anxiety worse in the rebound. Both disrupt sleep, which worsens panic. Avoid both.

Trying to logically argue with catastrophic thoughts during peak panic. Your amygdala is in control during peak panic, not your logical brain. Arguing with "I am dying" is futile mid-attack. Instead: label the thought ("I am having the thought that I am dying, but I am not actually dying"), breathe, and ground. Logic returns once the peak declines.

Context-Specific Protocol Variations

In Public (at work, in a store, on transit, in a meeting)

You cannot lie down or cry openly. You need the discreet version.

Grounding: Sit. Feel your feet in your shoes. Feel your chair or handrail. Use your senses silently: "I see the ceiling tile, the wall, the door. I feel my feet. I hear the hum of the room."
Breathing: Slow, quiet breathing at your desk, in your chair, or standing. Inhale 4, exhale 6, silently. Place one hand on your stomach and feel the rise and fall.
Self-talk: Repeat silently: "This is panic. It will peak in 10 minutes. I can stay here. It will pass."
Option: Excuse yourself to a bathroom or quiet space for 3 to 5 minutes and do the full protocol. Then return. Do not always escalate to "I need to leave." That reinforces avoidance.

At Home

You have privacy. Use it.

Posture: Sit on the couch or floor. Lean against a wall. If very dizzy, lie down.
Breathing: Full protocol. Slow inhale, extended exhale. 6 to 10 cycles.
Grounding: Use all five senses. Name things you see, feel, hear. Cool water on your wrists. A weighted blanket if helpful. Touch something textured (a pillow, a blanket).
Self-talk: "This is panic. I am at home. I am safe. The feeling will peak and pass."
After: Hydrate, eat protein and carbs, rest. Do not push yourself to be productive to prove you are fine. Recovery is part of the protocol.

At Work

Work-specific panic is common. The fear: "Everyone will see. I cannot leave my desk."

Posture: Sit at your desk. Feet on the floor. Back against your chair.
Breathing: Slow, quiet breathing. Inhale 4, exhale 6. If needed, go to the bathroom or an empty conference room for 3 to 5 minutes.
Grounding: Cold water on your wrists. Feel your chair. Name things you see silently.
Self-talk: "This is panic. I am safe at my desk. I can stay here and breathe. The feeling will pass. I can work again when I am ready."
After: Once you feel grounded, take 5 minutes. Drink water. Use the bathroom. Return to work when ready. Do not catastrophize about your performance or worry that everyone saw.

At Night (waking from panic)

Nighttime panic is terrifying because you are alone, in the dark, and confused about what is happening.

Posture: Sit up in bed or on the edge. Do not lie flat (it can feel suffocating). Turn on a low light.
Breathing: Slow exhalation breathing. Inhale 4, exhale 6 to 8. Feel your body on the bed.
Grounding: Name sounds: "I hear the refrigerator, the air conditioning, my own breathing." Feel the texture of your sheets. Feel your feet on the floor.
Self-talk: "This is a panic attack at night. It is not a heart attack. I am safe in my bed. The feeling will peak and pass in 20 minutes. I can go back to sleep once I am calm."
Do not: Do not check the time obsessively. Do not panic about losing sleep. Sleep will return.
Link: See our post on nighttime panic attacks for full guidance.

While Driving

Driving during panic is dangerous for you and others. Your reaction time is slow. Your attention is on your body.

Priority: Safety. If panic starts, turn on your signal, slow down, and move to the right lane. Look for the next safe exit, parking lot, or shoulder with good visibility.
Park safely. Turn off the engine or keep it on with hazards.
Use the 5-step protocol: Sit in the car. Feet on the pedals or floor. Slow breathing (inhale 4, exhale 6 to 8). Name what you see outside. Feel the seat. Repeat your phrase.
Wait 10 to 15 minutes. The peak will pass. Anxiety typically declines naturally within this time.
Resume carefully. Merge back into traffic when you feel able. Do not drive while panic is active. Your safety and the safety of others depend on it.
Prevention: If panic while driving is a pattern, discuss it with a therapist. Avoidance (not driving anymore) is the trap to avoid.

Recovery: Post-Panic Hangover (30 to 60 Minutes After Peak)

Thirty to 60 minutes after a panic attack, you may feel exhausted, tearful, foggy, shaky, sore, hungry, or thirsty. Your muscles tensed during panic, and they ache. Your adrenaline crashed, leaving you depleted. This is completely normal.

What to do:

Hydrate. Drink water. Panic causes dehydration.
Eat something with protein and carbohydrates. Your body used glucose. Replenish. A banana, crackers, nuts, yogurt, or a sandwich are fine.
Rest. It is okay to lie down, watch TV, or sit quietly. Your nervous system has been activated. Let it settle.
Journal or write what happened. Write down: the trigger (if known), what you felt, when it peaked, how long the full episode lasted, and how you handled it. This data is gold for therapy. It shows patterns and proves to your brain that panic is predictable.
Do not blame yourself. You did not cause this. Your nervous system misfired. That is it.
Do not ruminate. Thinking obsessively about the panic ("Why did this happen? What if it happens again? I am weak") starts the cycle again. Acknowledge it happened, note what you learned, and move on.

Prevent the Snowball: Avoidance Shrinks Your Life

The biggest risk after a panic attack is avoidance. You had panic at the grocery store, so you stop going to the grocery store. You had panic while driving, so you avoid driving. You had panic at work, so you call in sick or ask to work from home.

Each avoidance feels like relief in the moment. But over weeks and months, your world shrinks. Your fear grows because you never learn that the situation is safe. This is how panic attack becomes panic disorder with agoraphobia.

Per Barlow and Craske (2008), CBT for panic is built on exposure: deliberately approaching the situations you fear in a gradual, controlled way. You learn by doing, not by thinking.

The one thing you can do today:

Do not let panic stop you from doing what you would normally do. If you were planning to go to a store, go (even for 5 minutes). If you were at work, stay at work (unless you truly cannot). If you were driving, drive. Make the smallest commitment to normalcy, but make it.

This is the start of inhibitory learning: you are training your brain, in real time, that the situation is not actually dangerous.

When to Call 911 or Go to the ER

See the "GO TO THE ER NOW" box at the top of this post. If you have chest pain (heavy, crushing, radiating), severe shortness of breath at rest, fainting, confusion, or slurred speech, call 911. Do not guess. Cardiac disease must be ruled out.

Also go to the ER if:

This is your first-ever panic attack (to rule out medical mimics: thyroid storm, hypoglycemia, stimulant use, medication side effect, arrhythmia).
You believe this might be a heart attack and are unsure.
Symptoms are severe and you cannot function.

A "false alarm" ER visit is the right call. The cost of missing a heart attack is fatal.

See PAG row 17 for full panic attack vs heart attack guidance.

When to See a Therapist

You should see a healthcare provider if any of the following apply:

You have 2 or more panic attacks per month. One attack is an acute stress response; multiple attacks suggest panic disorder.
You are worried about having another attack between attacks (anticipatory anxiety). This is the signature of panic disorder and a clear indication for CBT-Panic.
You are avoiding places, activities, or people because you fear panic. Agoraphobia often develops from avoidance. Therapy is essential to stop this progression.
You are unsure whether this is panic or something else. A medical evaluation rules out cardiac disease, thyroid problems, medication side effects, and other mimics.
Panic is affecting your work, relationships, sleep, or quality of life. These are signs to seek professional support immediately.
You are thinking about harming yourself because of the panic. Call 988 (US) immediately.

First-Line Treatment: CBT for Panic Plus Interoceptive Exposure

If you see a therapist or psychiatrist and panic disorder is diagnosed, here is what to expect:

Cognitive Behavioral Therapy for Panic (CBT-Panic): A structured, time-limited therapy, usually 12 to 16 weeks. You learn the physiology of panic (adrenaline surge, fight-or-flight, the panic curve). You practice the breathing, grounding, and self-talk techniques in this post. You gradually expose yourself to the situations you fear (interoceptive exposure: deliberately triggering mild panic sensations in a safe, controlled way; and situational exposure: returning to places you avoid). Each time you face a feared situation and survive, you learn it is not actually dangerous. This is inhibitory learning, and it is the most powerful tool for panic disorder.

Per the APA Practice Guideline for anxiety disorders, CBT-Panic is first-line treatment and has the strongest evidence base (Craske et al., 2009).

Medications (SSRIs or SNRIs): Selective serotonin reuptake inhibitors (SSRIs) like sertraline, paroxetine, or fluoxetine, or serotonin-norepinephrine reuptake inhibitors (SNRIs) like venlafaxine or duloxetine, reduce the frequency and severity of panic attacks over 4 to 6 weeks. These are antidepressants, not sedatives. They are not habit-forming. They work on the brain's underlying panic circuitry and take 4 to 6 weeks to become effective.

Combined approach: CBT plus medication is often more effective than either alone.

Do not rely on benzodiazepines as your primary treatment. They carry dependence risk and interfere with learning (Otto, 2010). Use them short-term if needed, but pair them with CBT or an SSRI.

The Reassurance You Need

You will not die from a panic attack. Panic feels like a heart attack. Your body is screaming danger. But panic is not fatal. Your heart will keep beating. Your lungs will keep breathing. You will survive. About 11 percent of US adults have at least one panic attack per year per NIMH. You are not alone. You are not weak. You are not broken.
The attack will end. Panic cannot last indefinitely. By physiology, it peaks in 5 to 20 minutes and resolves within 20 to 30 minutes. Your body will run out of adrenaline. The wave will pass. It has for every person who has ever had a panic attack. It will for you.
You are not losing your mind. Panic makes you feel unreal, disconnected, dissociated, or terrified. These are symptoms of panic, not signs of psychosis or mental breakdown. Panic is treatable. Clarity will return.
With practice of this protocol, it gets easier. The first panic attack is the scariest. The second is slightly less scary because you survived the first. The third, even less. Each time you use the 5-step protocol and stay present instead of fleeing, you train your brain that panic is survivable and not a sign of danger. Recovery is possible.

FAQ: How to Stop a Panic Attack

Q: What is the fastest way to stop a panic attack? A: The fastest way is the 5-step protocol in this post: stop and ground, slow your breathing, label without judgment, stay where you are, and wait for the peak to pass. The peak usually comes within 10 minutes, and the attack resolves within 30 minutes. You cannot rush panic; it has a natural time course. But the techniques accelerate the process by calming your nervous system and preventing the reactive panic spiral.

Q: Can I take Xanax or a benzodiazepine to stop a panic attack? A: Benzodiazepines like Xanax (alprazolam) work quickly (15 to 30 minutes) and feel very effective in the moment. However, they carry risks: dependence (especially with frequent use), impaired memory and cognition, rebound anxiety, and they do not treat the underlying problem. They teach your brain that panic requires medication to fix, which can increase anxiety over time. Per Otto (2010), benzodiazepines can interfere with extinction learning that happens in CBT for panic. If your doctor prescribes a benzodiazepine, use it as directed, but also pursue CBT or an SSRI that addresses the root cause. Short-term benzodiazepine use (a few weeks during a crisis) is reasonable; long-term reliance is not ideal.

Q: Why does breathing deeply make me feel worse? A: "Breathing deeply" usually means taking huge, rapid breaths. This is hyperventilation, which lowers CO2 and worsens dizziness, tingling, and derealization. The fix: slow breathing. Inhale 4, exhale 6 to 8. Slow and steady. Extended exhale, not extended inhale. Do not hyperventilate.

Q: Do panic attacks always last exactly 10 minutes? A: No. The peak is usually 5 to 20 minutes. Full resolution (return to baseline) is usually 20 to 30 minutes. But some attacks peak at 5 minutes, others at 20. Some people resolve in 15 minutes, others in 45. The 10-to-30-minute range is typical, not absolute. Track your own timeline over several attacks to see your pattern.

Q: Can I stop a panic attack while I am driving? A: You can use the protocol, but you must prioritize safety. If panic starts while driving, pull over safely to the next exit, parking lot, or shoulder. Turn on hazards. Turn off the engine. Then use the 5-step protocol. Do not drive through a peaking panic attack. Wait 10 to 15 minutes until the peak passes, then resume driving. Your safety and the safety of others depend on it.

Q: What should I drink during a panic attack? A: Drink water. Room temperature or cool. Sip slowly. Avoid caffeine (increases anxiety), alcohol (worsens anxiety over time), and sugary drinks (spike then crash blood sugar). Water is grounding, hydrating, and safe.

Q: Do cold showers actually help stop a panic attack? A: Running cold water on your wrists or face activates the dive reflex and can lower heart rate acutely. Some people find this helpful; others find it shocking and worsening. If you want to try it, run cold water on your wrists or splash your face. Do not force a full cold shower during active panic if it feels overwhelming. The core protocol (breathing, grounding, self-talk) is more reliable.

Q: Why am I so tired after a panic attack? A: Panic is a full-body activation of the fight-or-flight system. Your muscles tense, your mind races, your adrenaline spikes, your heart works hard. After the peak, adrenaline crashes, and your body is depleted. This is post-exercise fatigue, essentially. Hydrate, eat, rest. The exhaustion will pass in 30 minutes to a few hours.
