How Long Can an Anxiety Attack Last?

An anxiety attack, also called a panic attack, begins suddenly and most often reaches its peak within 10 to 20 minutes, although some symptoms can continue for an hour or more.

That is the clinical answer, and it rarely matches the lived one. The racing heart fades while the shakiness, exhaustion, and dread stretch across the rest of the day. How long it lasts depends on what is driving the episode.

How Long Does an Anxiety Attack Last?

Most episodes are short, usually 10 to 20 minutes, though some symptoms persist longer.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) defines a panic attack as an abrupt surge of intense fear or discomfort that reaches a peak within minutes, accompanied by four or more physical symptoms such as heart palpitations, shortness of breath, chest pain, dizziness, numbness, and fear of dying.

Speed of onset is the defining feature. An episode that builds slowly across several hours and never spikes is not a panic attack.

Is an Anxiety Attack the Same as a Panic Attack?

Panic attack is a clinical term with specific diagnostic criteria behind it. Anxiety attack is not a clinical term but United States government health resources list it as an informal name for the same event.

People use anxiety attack and panic attack interchangeably, sometimes referring to a true panic attack, which peaks sharply within minutes. Other times, people refer to the slower, hours or days of building tension that does not spike.

This second experience is closer to generalized anxiety disorder (GAD) than an actual panic or anxiety attack. GAD involves excessive worry that occurs most days and lasts for at least six months.

When determining the difference between a panic and anxiety attack or GAD, what matters is the pattern: is it a sudden surge of anxiety that peaks and passes or a low-grade anxiety that will not switch off?

Why the Body Stays Switched On After the Peak Passes

The stress response runs on two clocks. The fast one, the sympathetic-adreno-medullar (SAM) axis, releases epinephrine and norepinephrine, which raise heart rate, blood pressure, and blood glucose. The slow one, the hypothalamic-pituitary-adrenal (HPA) axis, releases cortisol through a longer chain of signals.

The fast clock stops first. Once the threat disappears, the parasympathetic nervous system takes over and the body returns to base levels. The return is not instant, because acute stress narrows the airways and produces rapid, shallow breathing. Chest tightness and breathlessness can outlast the fear itself.

The slow clock keeps running. If the perceived fear does not pass, the body shifts into the resistance stage, continuing to secrete stress hormones and producing poor concentration, irritability, and frustration.

What Stretches an Attack Past 30 Minutes

Attacks can arrive in clusters, because panic attacks occur as often as several times per day in people with panic disorder.

Panic disorder is the diagnosis for recurring, unexpected panic attacks that leave a person dreading the next one. A single panic attack is not the same thing, and attacks also occur alongside other mood, anxiety, and substance use disorders.

Can an Anxiety Attack Last All Day?

A single panic attack almost never does. For people with panic disorder, a difficult day can be made up of separate anxiety surges, residual physical arousal between them, and fear of the next one. Some symptoms of a panic attack do continue for an hour or more.

Sustained stress produces its own daylong symptoms, which is why the experience can read as one long attack rather than several short ones.

Substances and Anxiety

Withdrawal from substances can include, and exacerbate, anxiety and panic attacks.

Anxiety is a withdrawal symptom in detox from alcohol and stimulants, as well as for benzodiazepine withdrawal, where panic attacks are common. Anxiety in benzo withdrawal can persist for months.

Even without a substance use disorder (SUD), anxiety that lasts for days should mean avoiding alcohol and reducing caffeine and other stimulants. When panic disorder and a substance use disorder occur together, gabapentin and mirtazapine are the recommended medications.

The Emergency Room Pattern

Chest pain is the second leading cause of emergency department visits, and roughly 80% of those cases are low risk, with no cardiovascular cause.

Among 375 adults treated for low-risk chest pain across six Indiana emergency departments, 75% screened positive for panic disorder and 42% had severe anxiety symptoms. Screens for depression and Post-Traumatic Stress Disorder (PTSD) were elevated in more than half the sample.

Only 2% to 8% of patients with low-risk chest pain and anxiety are identified as having an anxiety diagnosis, and both the anxiety and the chest pain often persist for months to years after the visit.

When Should Someone Go to the Emergency Room?

Chest pain is worth getting checked, even when you suspect it is anxiety. A panic attack can feel almost identical to a heart attack, and many people with panic disorder first seek care in the emergency room for exactly that reason. A clear cardiac workup is also the step that makes a panic disorder diagnosis possible, so it is never a wasted trip.

Treating Anxiety Attacks

Cognitive Behavioral Therapy (CBT) combined with medication is the standard approach to anxiety treatment, and selective serotonin reuptake inhibitors (SSRIs) are usually the first medication choice, with serotonin-norepinephrine reuptake inhibitors (SNRIs) as an alternative.

Breathing training is a large part of the work. Overbreathing during an attack makes the dizziness and tingling worse, and learning to breathe slowly and deliberately calms the nervous system down. Some programs use a small device that tracks your breathing while you practice, so you can see the change as it happens.

Sedatives are prescribed in limited amounts for anxiety and are not intended for daily use. Roughly 60% of patients undergoing treatment for panic disorder reach remission within 6 months.
