What should you know about common cold wheezing?

Wheezing is a high-pitched whistle, often heard when breathing out, caused by air moving through narrowed passages. A cold can inflame the airways or increase mucus, and this may bring out wheezing in someone with asthma or another airway condition. Wheezing is different from noisy breathing caused only by a blocked nose. Cough, chest tightness, fast breathing, or breathlessness makes the symptom more significant. A cold can also be followed by acute bronchitis, while children with croup may have a harsh cough and noisy breathing.

Sit upright, rest, avoid smoke and strong scents, and take small regular drinks. If a clinician has prescribed an inhaler or other airway medicine, use it according to your personal action plan. Do not borrow another person's inhaler. A pharmacist or clinician can check whether a cough or cold product is suitable, since some products may be inappropriate for children or people with other conditions. Note when the wheeze occurs and whether it follows activity, lying down, or medicine.

Call emergency services for severe breathlessness, blue or grey lips, inability to speak in full sentences, collapse, confusion, or visible pulling in of the ribs or neck while breathing. Seek same-day medical advice for new wheezing, worsening wheeze, chest tightness, rapid breathing, or poor response to a prescribed reliever. A baby or child with noisy breathing, reduced drinking, unusual sleepiness, or struggling to breathe needs prompt assessment.

Ask whether the sound is wheezing or upper-airway congestion, whether asthma or another airway problem could be involved, and how to use your prescribed reliever during future colds.
