Wheezing is a whistling sound made when breathing, usually while breathing out. It can occur with asthma, viral infections, allergies, or other conditions. Breathing effort and the child's overall appearance matter more than how loud the wheeze sounds.

Urgent Warning Signs - Check This First

If your child has a written asthma action plan, follow it first. Use prescribed quick-relief medicine and devices exactly as directed in that plan. A plan never replaces emergency care for severe breathing difficulty.

CALL 911 NOW

  • Severe trouble breathing: struggling for each breath, gasping, unable to speak or cry normally because of breathing difficulty, or becoming too tired to breathe normally

  • Blue, gray, or very pale lips or face; collapse, fainting, severe confusion, unusual drowsiness, or inability to stay awake

  • A severe allergic reaction with wheezing or breathing difficulty after food, medicine, an insect sting, or another exposure

  • Breathing symptoms rapidly worsening despite the child's prescribed rescue treatment, or any situation you believe is life-threatening

GET EMERGENCY MEDICAL CARE NOW

  • Ribs, breastbone, or skin above the collarbones pulling in with each breath; belly breathing, grunting, head bobbing in an infant, or severe fast breathing

  • A child who cannot walk, play, feed, drink, or speak normally because of breathing difficulty

  • A child whose prescribed rescue medicine has not helped as directed in the asthma action plan, or who is worsening after treatment

  • First-time wheezing with significant breathing difficulty, a young infant with wheezing, or wheezing with a possible inhaled object or sudden choking episode

CONTACT YOUR CHILD'S HEALTHCARE PROFESSIONAL TODAY

  • New wheezing, repeated wheezing, chest tightness, or cough that is interfering with sleep, school, play, feeding, or usual activity

  • Asthma symptoms that return before the time directed in the child's action plan for the next rescue treatment, or that are not improving as expected

  • A child needing their quick-relief medicine more often than usual, or whose asthma limits sports or normal activities

  • Cough or wheezing that occurs repeatedly with colds, exercise, cold air, smoke, pets, pollen, or other exposures

  • No written asthma action plan, no working spacer or other prescribed device, or uncertainty about how to use the child's inhaler or nebulizer

What Families May Notice

  • Wheezing, persistent cough, shortness of breath, chest tightness, faster breathing, or less tolerance for activity

  • In younger children: feeding less well, stopping often to catch breath, difficulty sleeping, irritability, or reduced play

  • Symptoms may worsen at night, with viral respiratory infections, exercise, smoke or vaping exposure, air pollution, allergies, or other personal triggers

  • Not every cough is asthma and not every wheeze can be heard without an examination. A clinician can help determine the cause.

Using an Asthma Action Plan

Every child with asthma should have a personalized written asthma action plan. Keep copies with caregivers, school or child care, and sports staff when appropriate. The plan should name the child's daily and quick-relief medicines, devices, triggers, and the exact steps for worsening symptoms. Do not stop, start, share, or change asthma medicines without the prescribing clinician's direction.

  • Check that inhalers and spacers are available, not expired, and used with the technique taught by the child's healthcare professional.

  • If a peak-flow meter is part of the action plan, use that child's own zones and personal-best value. Do not substitute general numbers for the plan.

  • Schedule follow-up when symptoms, medication needs, growth, activity level, or triggers change.

At Home While You Arrange Care

  • Keep the child upright, calm, and away from smoke, vaping aerosols, strong fragrances, and other known triggers.

  • Follow the child's written action plan and use prescribed medicine only as directed. Do not borrow another person's inhaler or use leftover oral steroids.

  • Encourage small, frequent drinks if the child can drink comfortably; do not force fluids when breathing is difficult.

  • Do not delay emergency care to try steam, cough medicine, or home remedies. These do not treat serious breathing distress.

Prevention and Ongoing Control

  • Avoid tobacco smoke, vaping aerosols, and cannabis smoke around children. Ask the child's clinician about other likely triggers.

  • Use daily controller medicine when prescribed, even when the child feels well, unless the prescribing clinician changes the plan.

  • Review inhaler and spacer technique at follow-up visits. Correct technique is an important part of effective treatment.

  • Keep routine vaccinations current and follow the child's care plan during respiratory illnesses.

Call Preparation

  • When symptoms began, possible triggers, and whether the child has fever, cough, congestion, chest pain, or a choking event

  • Breathing signs: retractions, fast breathing, ability to talk, walk, drink, or feed, and any color change or drowsiness

  • The child's asthma action plan, prescribed medicines and devices used, and the response to those treatments

  • Past emergency visits, hospitalizations, intensive care, or oral steroid treatment for asthma
