Quick answer: Go to the emergency room immediately if you have chest pain with cardiac red flags (crushing/radiating pressure, shortness of breath at rest, sweating, nausea), one-sided weakness or slurred speech (stroke), sudden severe headache, syncope, active suicidal ideation with a plan, or first-ever severe anxiety with no prior diagnosis. A typical panic attack with known history and no red flags does not require the ER. Instead, call 988 (US), your primary care doctor, or a mental health provider within 1 to 2 weeks to prevent recurrence. This post explains which symptoms require emergency care and which can be managed safely outside the hospital.
CRISIS: If you are in immediate danger or thinking of harming yourself, call 911 (US), 999 (UK), or 112 (EU) immediately, or go to your nearest emergency room. Text HOME to 741741 (Crisis Text Line, US). Call 988 (US Suicide and Crisis Lifeline) or 111 option 2 (UK mental health crisis).
GO TO THE EMERGENCY ROOM NOW
Call 911 or go to the nearest ER immediately if you have any of these symptoms:
Cardiac Red Flags (American Heart Association, ACEP)
- Crushing, squeezing, or severe pressure in the center of your chest
- Chest pain radiating to your left arm, jaw, neck, or back
- Shortness of breath or difficulty breathing at rest (not just during anxiety)
- Sweating, nausea, or feeling faint accompanying chest pain
- Chest pain combined with age 40 or older
- History of heart disease, high blood pressure, high cholesterol, or diabetes
- Family history of early heart disease
- Pain that does not resolve within 20 to 30 minutes
Stroke Red Flags (FAST Mnemonic, AHA Stroke Guidelines)
- Face: Facial droop or asymmetry (smile looks uneven)
- Arm: Sudden weakness or numbness in one arm (cannot lift or keep it up)
- Speech: Slurred speech or difficulty speaking or understanding others
- Time: Any of the above appearing suddenly = call 911 immediately
Pulmonary Embolism (PE)
- Sudden onset severe shortness of breath
- Sudden chest pain with shortness of breath
- Leg pain or swelling (call 911 or go to ER, especially if leg symptoms + breathing difficulty)
Psychiatric/Mental Health Crisis (SAMHSA, 988 Lifeline, ACEP)
- Active suicidal ideation with a plan or means to harm yourself (immediate ER risk)
- Intent to harm yourself or others
- Sudden onset hallucinations, delusions, or loss of touch with reality (psychosis)
- Severe dissociation or inability to function or keep yourself safe
- First-ever severe panic attack with no prior diagnosis (requires medical clearance to rule out cardiac or thyroid disease)
Call 911. Do not drive yourself unless absolutely necessary.
CALL 988 OR A CRISIS LINE INSTEAD OF (OR IN ADDITION TO) THE ER
Consider calling a crisis hotline for:
- Suicidal ideation without an immediate plan or means
- Severe emotional distress, wanting to talk to someone trained in crisis de-escalation
- Urge to self-harm but no immediate safety risk
- Suicidal thoughts that come and go but are not currently acute
In many jurisdictions, 988 can dispatch mobile crisis teams to stabilize you at home without a hospital visit. 988 and 911 coordinate, so calling 988 first does not delay emergency medical care if your situation escalates.

Don't Go to the ER If (Probably)
If all of the following are true, you likely do NOT need the ER:
- You have a confirmed anxiety or panic disorder diagnosis from a mental health provider
- Your symptoms match your usual panic attack pattern (same physical sensations, same triggers, same duration)
- No new or red-flag symptoms (see GO NOW list above)
- Symptoms resolve within 20 to 30 minutes
- You feel safe and have no thoughts of harming yourself
Do this instead:
- Call your primary care doctor or mental health provider within 1 to 2 weeks for a follow-up appointment or to refill any anxiety medication
- Use acute anxiety coping techniques (grounding, breathing, distraction)
- Tell a trusted friend or family member what is happening
- Develop a written rescue plan with your doctor or therapist for the next panic attack
Important: If you have never had a panic attack before, you should see a doctor (urgently care or next-day appointment, not ER) to rule out medical causes. Do not assume first-time severe anxiety is "just panic."
Why People with Anxiety Go to the ER (And Why It Often Is Not Needed)
Panic attacks mimic serious medical emergencies. The physical symptoms are nearly identical to heart attacks, strokes, and blood clots. Studies show approximately 25 percent of emergency department chest pain visits are attributed to panic disorder or other anxiety conditions, with no cardiac disease found.
Why panic feels like a cardiac emergency:
- Rapid or pounding heartbeat (tachycardia)
- Chest tightness or pressure
- Shortness of breath
- Dizziness or lightheadedness
- Nausea or stomach pain
- Sweating
- Sense of impending doom
These sensations are terrifying, and your brain correctly identifies them as "something is very wrong." The ER is the logical choice when you think you are having a heart attack.
The reality: In people with a known anxiety diagnosis and no new red flags, these symptoms are triggered by the fight-or-flight response, not tissue damage. The ER workup (ECG, troponin, chest X-ray) will be normal, which is reassuring but also means you spent money and time on testing that did not change your treatment plan.
Better approach for repeat episodes: Once you have had one ER visit with a normal cardiac workup, you know panic attacks do not cause permanent damage. Future attacks are still frightening but not life-threatening. Work with your doctor to develop a home action plan: rescue medication, grounding techniques, when to call your provider, and when (rarely) a repeat ER visit is needed.

First-Ever Severe Anxiety Episode: Go to the ER
If this is your first severe panic or anxiety attack, you should get medical clearance in an ER or urgent care setting.
Anxiety disorder is a diagnosis of exclusion. Before your doctor can say "this is anxiety," they must rule out:
- Cardiac arrhythmias (atrial fibrillation, supraventricular tachycardia, premature ventricular contractions)
- Hyperthyroidism or thyroid storm (overactive thyroid mimics anxiety: racing heart, sweating, tremor)
- Pheochromocytoma (rare tumor on adrenal gland that releases adrenaline spikes)
- Pulmonary embolism (blood clot in lungs)
- Hypoglycemia (dangerously low blood sugar, especially in people with diabetes)
- Medication or substance effects (stimulants, decongestants, caffeine, energy drinks, cocaine, amphetamines)
- Medication or alcohol withdrawal
- Myocardial infarction or acute coronary syndrome (heart attack or unstable angina)
The ER will perform:
- Vital signs check (blood pressure, heart rate, oxygen level, temperature)
- Electrocardiogram (ECG/EKG)
- Troponin blood test (cardiac enzyme)
- Complete blood count (CBC)
- Basic metabolic panel (BMP, including glucose)
- Thyroid function tests (TSH, free T4)
- Urine drug screen (if substance use is suspected)
- Chest X-ray (if respiratory symptoms)
- D-dimer or CT angiography (if PE is suspected)
If all tests are normal, your ER doctor can safely say "this is not a medical emergency, and your symptoms are consistent with anxiety or panic. Follow up with your primary care doctor for a full anxiety assessment and treatment plan."

What the ER Will Do for You (And What It Won't)
The ER will:
- Perform a medical evaluation to rule out cardiac, pulmonary, and metabolic emergencies
- Manage acute symptoms (oxygen if needed, IV fluids, monitoring)
- Prescribe short-term anti-anxiety medication (usually a benzodiazepine like lorazepam) to break a severe panic attack
- Provide reassurance and discharge instructions
- Refer you to psychiatry (if available) or direct you to follow-up care
The ER will NOT:
- Diagnose or treat underlying anxiety disorder (that is your PCP's or psychiatrist's job)
- Prescribe long-term anxiety medication (SSRIs, SNRIs, buspirone), which take weeks to work anyway
- Provide psychotherapy or coping skills training (that is a therapist's job)
- Solve the root cause of your anxiety
The key point: The ER is for medical clearance and acute crisis management, not long-term anxiety treatment. After the ER, you must see a primary care doctor and/or mental health provider to build a real treatment plan.

Alternatives to the ER When You Are Not in Red-Flag Territory
Urgent Care Clinic
- If you need same-day evaluation but symptoms are stable (no red flags)
- Can do ECG and basic labs
- Faster and cheaper than ER
- Appropriate for "first time, reassurance needed"
Primary Care Doctor (Same-Day or Next-Day Appointment)
- Call your doctor's office and explain you are having severe anxiety symptoms
- Many practices hold same-day slots for urgent (non-emergency) issues
- Your PCP knows your history and can often provide reassurance and short-term medication
Crisis Stabilization Center (Some US States)
- Community mental health crisis center; sits between 911 and long-term therapy
- Can provide psychiatric evaluation, de-escalation, and short-term medication without hospitalization
- 4 to 24-hour stay, not a hospital admission
- Call 988 to ask if one is available in your area
988 Lifeline
- 24/7 crisis counseling and de-escalation
- Can dispatch a mobile crisis team in many areas (in-home evaluation)
- Does not require hospital visit but can coordinate one if needed
Telehealth Urgent Psychiatry
- Several platforms (Psyche, GigaMed, others) offer same-day or within-hours virtual psychiatric visits
- Can prescribe short-term anxiety medication
- Faster than scheduling a traditional appointment
- Check your insurance coverage first

Safety Plan Between Panic Attacks
To prevent repeat ER visits, work with your doctor or therapist to build a crisis plan:
- Identify your triggers (stress, caffeine, lack of sleep, specific situations). Avoid or reduce exposure where possible.
- Keep a rescue medication if prescribed (fast-acting SSRI, buspiron, or benzodiazepine). Know when and how to use it before you are in crisis.
- Learn grounding or breathing techniques (5-4-3-2-1 grounding, box breathing, progressive muscle relaxation). Practice them when calm so you can use them during panic.
- Write down your action plan:
- What panic symptoms look like for me?
- What is my first step? (Breathing exercise, call someone, etc.)
- When do I call my doctor?
- When do I call 988?
- When do I call 911?
- Who is my support person? (trusted friend, family member, partner)
- Know the nearest urgent care and ER (in case you do need one after trying the above).
- Schedule regular follow-ups with your PCP or mental health provider (not just when in crisis).
When Repeated ER Visits Are a Pattern
If you are going to the ER for anxiety more than once a month, it is a sign that your underlying anxiety is undertreated. This is NOT a personal failure. It is a signal to escalate your care:
- See a psychiatrist or psychiatric nurse practitioner (not just your PCP). Medication optimization often requires specialist expertise.
- Start or intensify cognitive-behavioral therapy (CBT) for panic. It is the gold standard and is more effective than medication alone. Seek out a therapist trained in panic-specific CBT protocols.
- Consider a combination approach: medication + therapy works better than either alone.
- Rule out comorbid conditions: depression, alcohol or substance use, chronic pain, insomnia, or medical conditions (thyroid, cardiovascular) that can worsen anxiety and make it harder to treat.
Repeated ER visits are expensive, traumatic, and disruptive. If this is you, do not accept "just manage it." Seek specialist psychiatric care.
Frequently Asked Questions
Q: Is it ok to go to the ER for a panic attack if I am very scared?
A: Fear itself is not a reason to go to the ER if you have no red flags (chest pain with cardiac symptoms, shortness of breath at rest, stroke symptoms, suicidal ideation). Fear is part of anxiety. Going to the ER will not teach your brain that panic is not dangerous; it can actually reinforce the belief that you need emergency care for anxiety. Instead, call 988 or a trusted person. Sit through the panic with coping techniques. You will be ok. Your doctor can help you build a plan to prevent future severe episodes.
Q: Can anxiety cause a real heart attack?
A: Anxiety itself does not directly cause a heart attack (myocardial infarction), which requires a blocked coronary artery. However, severe chronic anxiety can increase long-term cardiovascular risk through stress hormone overload, inflammation, and behavioral factors (smoking, poor diet, inactivity). If you have cardiac risk factors (age, family history, smoking, high cholesterol, diabetes, obesity), you are at higher risk for both anxiety AND heart disease. Get a medical evaluation once to rule out cardiac disease, then work on anxiety treatment.
Q: What if I cannot afford the ER?
A: If cost is preventing you from getting care:
- Call 988 first. It is free and can help you decide if the ER is truly necessary.
- Go to an urgent care clinic instead of the ER (cheaper, still provides evaluation).
- Ask your ER or urgent care clinic about financial assistance programs.
- Call your local health department or SAMHSA (1-800-662-4357) for low-cost mental health services and community health centers.
- Telehealth psychiatry is often cheaper than in-person visits.
- Prevention (therapy, medication, lifestyle) is cheaper than repeated ER visits.
Q: Can I call 988 instead of 911 if I am having a panic attack?
A: If your panic attack has red flags (chest pain with cardiac symptoms, stroke symptoms, suicidal ideation), call 911, not 988. 988 is for mental health crises that are not immediately life-threatening. If you are unsure, call 911. They can transfer you to 988 if appropriate. It is better to call 911 and be told "you are ok" than to call 988 for a true medical emergency.
Q: How long does it take to go through the ER for anxiety?
A: An ER visit for anxiety evaluation typically takes 2 to 4 hours, including triage (15 to 30 minutes), medical workup (ECG, blood tests, vitals, imaging if needed: 1 to 2 hours), doctor evaluation (30 to 60 minutes), and discharge or psychiatric consultation. Busy ERs may take longer. You will get a bill afterward, often $1,000 to $2,000 or more, even with insurance.
Q: Should I go to the ER if I am having my second or third panic attack?
A: If you have already had one ER visit with normal cardiac tests, a second panic attack probably does not require the ER again (unless it has new red flags). Call your doctor, 988, or use home coping techniques. Going to the ER every time reinforces the belief that panic is dangerous and that you need emergency care. Work with your doctor to prevent the next episode instead.
Q: Is it suicidal ideation if I have fleeting thoughts of "I want to die" but I don't have a plan?
A: Fleeting thoughts are not the same as active suicidal ideation with intent. However, do not dismiss them. Call 988 or your therapist to talk about them. If you do develop a plan or the thoughts become persistent and you feel you might act on them, that is a reason to call 911 or go to the ER. The line between "intrusive thoughts" and "actionable ideation" can blur. When in doubt, reach out.
Q: What if my anxiety is so bad I cannot function, but I have no red flags? Do I need the ER?
A: Non-functionality is distressing but not an ER-level emergency. Call your doctor for urgent appointment (same-day or next-day). Describe that your anxiety is worsening and you need help. This is a sign to escalate treatment (medication adjustment, therapy intensification, psychiatrist referral), not to go to the ER. The ER cannot treat the root anxiety disorder; your doctor and therapist can.
Q: Should I bring someone with me to the ER if I am going for anxiety?
A: Yes. Having a trusted support person present can help you stay calm, answer questions you might forget due to panic, and provide comfort. Ask them to help you communicate your symptoms clearly to the doctor.
