Asthma cough treatment: what you should know

A clinician may use a reliever inhaler for rapid symptom relief and a controller inhaler for ongoing inflammation, depending on the pattern and severity of symptoms. Follow the written asthma action plan and the prescribed inhaler schedule rather than changing doses on your own.

Asthma can present with a dry or mucus-producing cough, sometimes alongside wheezing, chest tightness or shortness of breath. Cough may become more noticeable at night, during exercise, after a respiratory infection, or following exposure to smoke, dust, fragrances, cold air or allergens.

Cough alone does not establish asthma because reflux, nasal drainage, infection and other airway conditions can produce a similar symptom. Assessment may include the symptom pattern, chest examination, breathing tests and the response to appropriate treatment.

Use each inhaler exactly as prescribed and have a clinician or pharmacist check your technique. A spacer may help medicine from a suitable metered-dose inhaler reach the lungs. Rinse your mouth after an inhaled corticosteroid if instructed.

Track when the cough occurs, what seems to trigger it and how often reliever medicine is needed. Reduce avoidable exposure to tobacco smoke, vaping aerosols, dust and strong scents. Treating associated nasal allergy may also reduce upper-airway irritation. If symptoms keep returning, request a review of the diagnosis, inhaler technique, adherence and treatment plan.

Arrange a prompt medical review if the cough disrupts sleep or normal activity, keeps recurring, is accompanied by wheezing or chest tightness, or is not responding as expected to the prescribed plan. Increasing reliance on a reliever inhaler also warrants review.

Seek emergency help for severe breathlessness, difficulty speaking in full sentences, bluish or grey lips, confusion, drowsiness, marked chest pulling with each breath, or symptoms that continue to worsen after using prescribed reliever medicine. Follow the emergency steps in the asthma action plan while help is being arranged.

Ask whether the cough pattern fits asthma, whether breathing tests are appropriate, and which inhaler is intended for immediate relief versus daily control. Confirm how to recognise worsening symptoms, when to use a spacer, what to do after a missed dose, and when the action plan says to seek urgent help.
