Panic Attacks and Panic Disorder: Symptoms, Causes, and Treatment
Updated: 3 days ago
Medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: October 2026
A panic attack is a sudden burst of intense fear that triggers strong physical reactions, such as a racing heart, sweating, chest pain, and dizziness, even when there is no real danger. Most people have only one or two, but repeated, unexpected attacks with ongoing fear can signal panic disorder. Treatment, mainly cognitive behavioral therapy and certain medicines, is very effective, and getting checked promptly matters because symptoms can mimic a heart attack [1].
Quick Answer: What is a panic attack?
A panic attack is a sudden episode of intense fear with severe physical reactions, such as a pounding heart, shortness of breath and chest pain, when there is no real danger. Attacks usually peak within minutes and are not life-threatening. Recurrent attacks with ongoing fear may mean panic disorder. Cognitive behavioral therapy and SSRIs are first-choice treatments. [1] [2]
What the research says
CBT beats placebo across anxiety disorders, with a smaller edge for panic. A meta-analysis of 41 randomized placebo-controlled trials (2,843 patients) found a moderate overall effect of CBT on target disorder symptoms (Hedges’ g = 0.56) and an odds ratio of 2.97 for response; effects were large for OCD and generalized anxiety but small to moderate for panic disorder, which the authors said needs more effective treatments (Carpenter et al., Depress Anxiety, 2018).
What Is a Panic Attack?
A panic attack is a sudden episode of intense fear that triggers severe physical reactions when there is no real danger or obvious cause. It can be very frightening. You might think you are losing control, having a heart attack, or even dying [1].
Many people have just one or two panic attacks in their lives, and the problem goes away, perhaps when a stressful situation ends. But if you have repeated, unexpected attacks and spend long periods in constant fear of another, you may have a condition called panic disorder. Panic attacks are not life-threatening, but they can significantly affect your quality of life. The good news is that treatment can be very effective [1].
Key fact | What it means |
The episode | Sudden, intense fear with severe physical reactions |
How long | Symptoms usually peak within minutes |
Life-threatening? | No, but symptoms can mimic a heart attack |
Panic disorder | Recurrent unexpected attacks plus at least one month of ongoing fear or behavior change |
Outlook | Treatment can be very effective |
What Are the Symptoms of a Panic Attack?
Panic attacks usually start suddenly, without warning. They can strike at any time: while driving, at the mall, fast asleep, or in a business meeting. They can be occasional or frequent. Symptoms usually peak within minutes, and you may feel worn out afterward. One of the worst parts is the fear of having another, which can lead you to avoid places where one might happen [1].
The physical and emotional symptoms of a panic attack.
Physical Symptoms
Heart: rapid, pounding heartbeat [1].
Breathing: shortness of breath or tightness in the throat [1].
Skin and temperature: sweating, chills, or hot flashes [1].
Stomach: nausea or abdominal cramping [1].
Head and nerves: headache, dizziness, lightheadedness, faintness, numbness, or tingling [1].
Movement: trembling or shaking [1].
Chest: chest pain [1].
Emotional Symptoms
When should you see a doctor about panic attacks?
If you have panic attack symptoms, seek medical help as soon as possible. Panic attacks are intensely uncomfortable but not dangerous. They are hard to manage alone, though, and may get worse without treatment. Their symptoms can also look like those of other serious problems, such as a heart attack, so see your primary care provider if you are not sure what is causing them [1].
Situation | What to do |
First-ever panic attack symptoms | Get evaluated promptly to rule out heart and other conditions |
Recurrent attacks | Seek treatment; they may get worse without it |
Constant fear between attacks | Ask your provider about panic disorder screening |
Unsure of the cause | Err on the side of a medical evaluation |
What Causes Panic Attacks?
No one knows exactly what causes panic attacks or panic disorder, but several factors may play a role. They may come on suddenly at first, but over time they are usually triggered by certain situations. Some research suggests the body’s natural fight-or-flight response is involved: if a grizzly bear charged you, your heart and breathing would speed up to prepare for danger. Many of the same reactions happen in a panic attack, but it is not known why they occur when no danger is present [1].
Possible factor | How it may contribute |
Genetics | A family history may raise risk |
Health conditions | Asthma or heart conditions can create uncomfortable body sensations |
Major stress | Life stress can play a role |
Learned reactions | Learning to react to panic symptoms with anxiety, fear, and avoidance |
Temperament | Greater sensitivity to the physical signs of stress |
Brain function | Certain changes in how parts of the brain work |
What Are the Risk Factors?
Panic disorder often starts in the late teens or early adulthood, affects more women than men, and is more likely with family history, major stress, trauma or childhood abuse. These factors may raise your risk [1]:
Family history of panic attacks or panic disorder.
Major life stress, such as the death or serious illness of a loved one.
Traumatic events, such as sexual assault or a serious accident.
Big life changes, such as divorce or a new baby.
Smoking or heavy caffeine intake.
Childhood abuse, including physical or sexual abuse.
What Complications Can Develop?
Left untreated, panic attacks and panic disorder can affect almost every area of life. You may become so afraid of more attacks that you live in constant fear. For some people, panic disorder includes agoraphobia: avoiding places or situations because you fear you could not escape or get help during an attack. You may come to rely on others to leave your home [1].
Specific phobias, such as fear of driving or leaving home.
Frequent medical visits for health worries.
Social withdrawal and avoiding social situations.
Problems at work or school.
Other mental health conditions, including depression and other anxiety disorders.
Suicidal thoughts or a higher risk of suicide, and alcohol or other substance misuse.
Financial problems.
If you are having thoughts of suicide, contact local emergency services right away. In the U.S., you can call or text 988 to reach the Suicide & Crisis Lifeline.
Can Panic Attacks Be Prevented?
There is no sure way to prevent panic attacks or panic disorder, but these steps may help [1]:
Get treatment early to stop attacks from getting worse or more frequent.
Stick with your treatment plan to help prevent relapse.
Stay physically active, which may help protect against anxiety.
How Are Panic Attacks Diagnosed?
Your primary care provider will work out whether you have panic attacks, panic disorder, or another condition, such as a heart or thyroid problem, with similar symptoms [2]. You may have several evaluations:
Complete physical exam to rule out physical causes.
Blood tests to check your thyroid and other possible conditions.
Heart tests, such as an electrocardiogram (ECG or EKG), to check heart rhythm.
Psychological evaluation covering symptoms, fears, stressful situations, relationship problems, situations you avoid, and family history.
Self-assessment questionnaire, which may include questions about alcohol or substance use.
Panic Attacks vs. Panic Disorder
Not everyone who has panic attacks has panic disorder. For a diagnosis, the DSM-5-TR, published by the American Psychiatric Association, lists these points [2]:
Criterion | What it means |
Frequent, unexpected attacks | Attacks happen repeatedly without warning |
One month or more of aftermath | After at least one attack: ongoing worry about another, continued fear of consequences (losing control, having a heart attack, "going crazy"), or behavior changes such as avoiding triggers |
Not caused by something else | Attacks are not caused by drugs, a medical condition, or another mental health condition such as social phobia or OCD |
If you have panic attacks but not panic disorder, you can still benefit from treatment. Untreated panic attacks can get worse and develop into panic disorder or phobias [2].

How Are Panic Attacks Treated?
Treatment can lower the intensity and frequency of attacks and improve how you function day to day. The main options are psychotherapy and medicines. You may be offered one or both, depending on your preference, your history, how severe the panic disorder is, and whether you can see therapists trained in treating it [2].
The three pillars of panic attack treatment: therapy, medicine, and self-care.
Psychotherapy
Psychotherapy, or talk therapy, is considered an effective first-choice treatment. It helps you understand panic attacks and learn to cope. Cognitive behavioral therapy (CBT) helps you learn through your own experience that panic symptoms are not dangerous. Your therapist helps you gradually re-create the symptoms of an attack in a safe, repeated way. Once the body sensations no longer feel threatening, the attacks begin to fade, and you can overcome fears of places you avoided because of panic [2].
Results take time and effort. Symptoms may start to ease within several weeks and often drop a lot or go away within several months. You may have occasional maintenance visits to keep attacks under control or treat a recurrence [2].
Medications
Medicines can reduce panic symptoms, as well as depression if that is also a problem. Several types have been shown to work [2]:
Medication class | Details |
SSRIs | Generally safe with a low risk of serious side effects; usually the first choice. FDA-approved for panic disorder: fluoxetine (Prozac), paroxetine (Paxil, Pexeva), and sertraline (Zoloft) |
SNRIs | Another antidepressant class; venlafaxine (Effexor XR) is FDA-approved for panic disorder |
Benzodiazepines | Sedatives; FDA-approved options include alprazolam (Xanax) and clonazepam (Klonopin). Used only short term because they can be habit-forming and cause dependence; a poor choice with alcohol or drug problems; can interact dangerously with other drugs |
If one medicine does not work well, your doctor may switch you or combine medicines. It can take several weeks after you start before you notice improvement. All medicines carry a risk of side effects, and some are not recommended in situations such as pregnancy, so discuss risks with your doctor [2].
Lifestyle and Home Remedies
Stick to your treatment plan.
Join a support group to connect with others facing the same problems.
Avoid caffeine, alcohol, smoking, and recreational drugs, all of which can trigger or worsen attacks.
Practice stress management and relaxation, such as yoga, deep breathing, and progressive muscle relaxation (tensing one muscle at a time, then releasing).
Get physically active; aerobic exercise may have a calming effect on mood.
Get enough sleep so you do not feel drowsy during the day.
Alternative Medicine
Some dietary supplements have been studied for panic disorder, but more research is needed on their risks and benefits. Herbal products and supplements are not monitored by the FDA the way medicines are, so you cannot always be sure what you are getting or whether it is safe. Some can interfere with prescription medicines or cause dangerous interactions, so talk to your doctor before trying any [2].
How should you prepare for an appointment about panic attacks?
If you have had signs or symptoms of a panic attack, make an appointment with your primary care provider. After an initial evaluation, you may be referred to a mental health professional [2]. Before you go, make a list of:
Your symptoms, including when they first occurred and how often they happen.
Key personal information, such as past trauma and major stress before your first attack.
Other physical or mental health conditions.
All medicines, vitamins, herbs, and supplements, with doses.
Questions to ask, such as what is causing your symptoms, whether a medical problem could be responsible, whether tests are needed, and what you can do now.
Ask a trusted family member or friend to come with you if possible. If you are referred to a mental health professional, you might ask whether you have panic attacks or panic disorder, what treatment they recommend, how long therapy and medicine will last, what the side effects are, and how progress will be tracked. Expect questions about when attacks happen, how often you fear another, what you avoid, family history, caffeine, alcohol and drug use, and your exercise habits.
What is the bottom line on panic attacks and panic disorder?
Panic attacks are sudden episodes of intense fear with powerful physical reactions that strike even without real danger. They are not life-threatening, but they are not something to manage alone, and untreated attacks can grow into panic disorder, phobias, and avoidance that affect nearly every part of life. Because symptoms can resemble a heart attack, prompt medical evaluation is the first step. After that, treatment works: CBT retrains how your body responds to panic sensations, medicines such as SSRIs and SNRIs reduce attack intensity, and lifestyle steps such as cutting caffeine, exercising, and sleeping well support recovery.
Your next step: If you have had panic attack symptoms, schedule an appointment with your primary care provider to rule out physical causes and start a treatment plan.
