How to stop wheezing

Wheezing is a musical or whistling sound caused by narrowed airways. It may occur with asthma, a chest infection such as acute bronchitis, COPD, or an allergic reaction. Allergic rhinitis can also irritate the upper airways, while bronchiolitis is a possible cause in young children. The sound may be more noticeable when breathing out, but any new or recurring wheeze deserves attention.

Stop exercising and rest in an upright position. Loosen tight clothing and take slow, comfortable breaths. Leave smoky, dusty or strongly scented surroundings and avoid cold air if it worsens the sound. If a clinician has prescribed an inhaler, follow its instructions and do not share someone else’s medicine. A nebuliser treatment may be used by a healthcare professional when inhaled medicine needs to be delivered with monitored support.

Call emergency services for severe breathlessness, blue or grey lips, confusion, fainting, inability to speak normally, or swelling of the lips, tongue or throat. Sudden wheezing after food, medicine or an insect sting may signal anaphylaxis. Arrange medical assessment for a first episode, wheezing that keeps returning, fever, chest pain, or symptoms that do not settle with your prescribed plan.

Ask what is triggering the wheeze, whether you need breathing tests, how to use your inhaler, and which changes mean your action plan should be stepped up. Mention smoking or vaping exposure, allergies, recent infections, and every medicine you take.
