Asthma Attack: What to Do Step by Step

During an asthma attack, use your rescue inhaler (albuterol) — two puffs, wait 20 minutes, and repeat if needed. If symptoms are severe, worsen rapidly, or do not improve after two rounds, call 911. Always follow a written asthma action plan that specifies what to do in green, yellow, and red zones.

What is happening in your airways during an asthma attack?

During an asthma attack (also called an acute exacerbation), three things happen simultaneously: the muscles around the airways tighten (bronchoconstriction), the airway lining becomes inflamed and swollen, and extra mucus is produced. Together these narrow the passages through which air flows, making it harder to breathe out fully. The characteristic wheeze is caused by air pushing through these narrowed passages 1.

This is why rescue inhalers (bronchodilators) work — they relax the muscle tightening. What they cannot immediately fix is the underlying inflammation, which is why controller medications taken every day matter for prevention.

Step-by-step: what to do during an asthma attack

Step 1: Sit upright Staying upright allows the lungs to expand more fully than lying down.

Step 2: Use your rescue inhaler Take 2 puffs of your short-acting bronchodilator (SABA), typically albuterol, using a spacer (valved holding chamber) if you have one. Using a spacer improves medication delivery into the lungs significantly and reduces the amount deposited in the mouth and throat 2.

Step 3: Wait and reassess Wait 20 minutes. If symptoms have clearly improved, rest and continue monitoring.

Step 4: Repeat if needed If symptoms persist, take 2 more puffs and wait another 20 minutes.

Step 5: Escalate if not improving If you have used your inhaler twice and symptoms are not improving — or are worsening — call 911 or have someone drive you to an emergency department. Do not drive yourself 1.

Step 6: Follow your action plan Your written asthma action plan (from your clinician) will specify exactly how many puffs to take, when to add oral corticosteroids if prescribed, and when to call for help based on your personal peak flow readings or symptom severity 2.

Signs that the inhaler is not working — call 911

These signs indicate a severe or life-threatening asthma attack:

  • You cannot complete a full sentence without stopping to breathe
  • Your lips or fingernails look blue or grayish (cyanosis)
  • The skin between your neck and collarbones, or between your ribs, is visibly pulling inward with each breath
  • You feel exhausted or confused
  • Wheezing suddenly stops — this can mean the airways are almost completely blocked, not that the attack is resolving
  • Your rescue inhaler has had no effect after two rounds

Call 911 immediately for any of these signs 1.

What is an asthma action plan and do I need one?

An asthma action plan is a written document — ideally created with your clinician — that tells you exactly what to do based on your symptoms or peak flow meter readings. The three zones are 2:

  • Green zone (doing well): No symptoms, continue daily controller medication as prescribed
  • Yellow zone (caution): Symptoms present, use rescue inhaler as directed, consider oral corticosteroids if prescribed, contact clinician
  • Red zone (medical alert): Severe symptoms, rescue inhaler not helping — use it immediately, call 911

Having this plan written down and accessible — at home, at work, in a child's school — reduces hesitation and improves outcomes during acute attacks 2.

If you do not have a written action plan, a Gale primary care clinician can create one with you at your next visit.

After an asthma attack: follow-up care

A significant asthma flare — especially one that required emergency care or a course of oral steroids — is a signal that your everyday asthma control needs review. Common reasons attacks occur include:

  • A trigger exposure that can be reduced (mold, pet dander, smoke)
  • Inadequate controller medication (dose or type)
  • Incorrect inhaler technique
  • An illness (respiratory virus is a very common asthma trigger) 1

Schedule a follow-up with your clinician within a week of any significant attack to review your controller regimen and update your action plan.

Common questions

Can I use my rescue inhaler more than twice during an attack?

Using a rescue inhaler more than twice in 20 minutes without improvement is a signal to seek emergency care rather than continue self-treating at home. Overuse of rescue inhalers is also a sign that asthma is not well controlled and that your daily medication regimen should be reviewed.

What should I do if I forget my rescue inhaler?

Try to remain calm, sit upright, and breathe slowly and steadily. Call 911 or have someone take you to the nearest emergency department if symptoms are significant. If possible, contact someone who can bring your inhaler to you — but do not delay emergency care for severe symptoms while waiting.

Is it normal to feel worse at night during an asthma attack?

Yes. Asthma symptoms, including nocturnal worsening, are a recognized pattern often linked to airway inflammation cycles, cooler air temperatures, and lying flat. Frequent nighttime symptoms are a sign that asthma is not optimally controlled and worth discussing with your clinician.

Should children with asthma have a separate action plan for school?

Yes, this is strongly recommended. Schools need a copy of the child's action plan and ideally should have a rescue inhaler on file. Speak with your child's pediatrician or primary care clinician to prepare school documentation.

Call 911 if any of these are present

  • —Cannot speak in full sentences due to breathing difficulty
  • —Blue or gray lips or fingernails
  • —Skin visibly retracting between ribs or at the base of the neck with each breath
  • —Rescue inhaler has given no relief after two rounds
  • —Sudden silence after wheezing — this is a danger sign, not improvement
  • —Confusion or extreme exhaustion during the attack

Call 911 immediately for severe asthma symptoms. Use your rescue inhaler while waiting for help. Do not drive yourself.
