Symptoms
A panic attack usually peaks within about ten minutes and can include:- Racing or pounding heart: Palpitations are often the most frightening symptom.
- Shortness of breath: A smothering or choking sensation, sometimes with chest pain or tightness.
- Sweating, trembling, or chills: The body's alarm system fires at full strength.
- Dizziness, nausea, or tingling: Lightheadedness and numbness in the hands or face are common.
- A sense of unreality or dread: Many people fear they are dying or losing control.
Causes and Risk Factors
There is no single cause, but several factors raise risk:- Family history: Panic and other anxiety disorders tend to run in families.
- Major stress: Attacks often begin during or after periods of significant life stress or loss.
- Other mental health conditions: Generalized anxiety disorder and depression frequently occur alongside panic disorder.
- Stimulants: Caffeine, nicotine, and some medications can provoke or worsen attacks.
Diagnosis
Because panic symptoms mimic medical problems, your physician will first make sure nothing else explains them. Evaluation may include a physical exam, an electrocardiogram, and blood tests — an overactive thyroid (hyperthyroidism) and rhythm disturbances such as supraventricular tachycardia can feel remarkably like panic. Once medical causes are excluded, the diagnosis is made from your history alone; no scan is required. Keeping a brief diary of attacks — when they happen, what you felt, and what was going on around you — often speeds the diagnosis and reveals triggers.Treatment
Most people improve substantially with treatment, and combining psychotherapy with medication often works better than either approach alone:- Cognitive behavioral therapy (CBT): The best-studied therapy for panic disorder, it teaches you to reinterpret the physical sensations of an attack and gradually retrains the brain's alarm response.
- Antidepressant medications: SSRIs such as sertraline and escitalopram are first-line drugs; they take several weeks to reach full effect and are used daily, not as needed.
- Benzodiazepines: Alprazolam and clonazepam relieve symptoms quickly but can cause dependence, so they are generally reserved for short-term or occasional use.
- Lifestyle measures: Cutting back caffeine, exercising regularly, keeping a steady sleep schedule, and practicing slow breathing all reduce attack frequency.
When to Seek Immediate Care
Never assume new chest pain is panic. If chest pain occurs with exertion, lasts more than a few minutes, spreads to the arm or jaw, or comes with sweating and breathlessness, call 911 — heart problems must be ruled out first. Panic disorder responds very well to care, and no one should have to organize life around fear of the next attack.

Panic disorder is highly treatable, and yet many people stay stuck for years, because the first weeks of medication feel worse before they feel better, an as-needed pill quietly undermines the therapy, and the habits that keep the alarm system primed are never addressed. This is what makes the difference.
The first weeks on an SSRI
Sertraline or escitalopram is started at half the usual dose because people with panic are unusually sensitive to the jitteriness SSRIs can cause in the first one to two weeks, which is a side effect and not a worsening of the disorder. Benefit begins around four to six weeks and builds for three months; stopping before then is the most common reason treatment fails. Once well, treatment continues for at least a year before a slow taper, and our SSRI discontinuation article explains why the taper is gradual. Venlafaxine or paroxetine are alternatives when the first choice does not suit.
Why an as-needed benzodiazepine holds you back
Alprazolam or clonazepam can bridge the first few weeks while an SSRI takes effect, on a fixed schedule for a limited time. Taken at the first flicker of an attack, it teaches the brain that the attack was dangerous and that the pill prevented catastrophe, which is exactly the belief that therapy exists to unlearn. Long-term use brings tolerance and dependence, and our benzodiazepine deprescribing article covers how it is stopped safely.
What therapy actually involves
Cognitive behavioral therapy for panic runs about twelve to sixteen sessions and centers on deliberately producing the feared sensations, spinning to get dizzy, breathing through a straw, running in place, until the body learns they are harmless. Avoiding the sensations, carrying water or a pill just in case, and sitting near exits are safety behaviors that keep the fear alive. Telehealth delivery works as well as in person, and our St. Pete mental health guide lists local options.
What quietly keeps the alarm primed
Caffeine, nicotine, cannabis, decongestants, and the rebound after evening alcohol each provoke attacks, and short sleep lowers the threshold for all of them; insomnia and panic usually have to be treated together. Skipped meals cause the shakiness and racing heart that start an attack, and Florida heat and dehydration produce lightheadedness and palpitations that are easily misread as one; our palpitations article covers when the heart itself needs checking. Hurricane season is a predictable stress point worth planning for.
Conditions that overlap or imitate
Supraventricular tachycardia and hyperthyroidism are excluded once, not repeatedly; after that, further cardiac testing tends to reinforce the fear. Generalized anxiety disorder, depression, PTSD, and alcohol use disorder commonly coexist and change the plan; our panic disorder versus generalized anxiety article explains the difference. Our psychiatric team coordinates medication and therapy referral. The National Institute of Mental Health and MedlinePlus publish patient guidance on treatment.
