Inhaler for a cough – when asthma needs checking
A cough does not automatically need an inhaler. Learn when cough can fit an asthma pattern and when a clinician should look for another cause.
A cough has many causes
Cough can come from a viral infection, allergies, reflux, smoking or vaping, a medicine side effect, asthma and other conditions. An inhaler is not a general cough remedy. A clinician considers the pattern, breathing symptoms, triggers, examination and sometimes testing before choosing treatment.
Clues worth taking to a clinician
- Cough or wheeze that comes and goes, especially at night or with exercise.
- Chest tightness or breathlessness with triggers such as cold air, dust or pollen.
- A cough that keeps returning after apparently minor infections.
- Symptoms that improve and then recur when a reliever wears off.
These clues do not prove asthma. They tell you that a proper assessment may be more useful than trying somebody else's inhaler.
Prepare for the assessment
- Record when the cough happens and what triggers it.
- List any wheeze, chest tightness, breathlessness or night waking.
- Bring every inhaler or cough product you have tried.
- Ask for a technique check if an inhaler was prescribed.
Cough with breathing danger is urgent
Common questions
- Can I use an inhaler for a cough?
- Only use an inhaler prescribed or recommended for you after assessment. A cough can have many causes and an inhaler is not a general cough medicine.
- Does a cough at night mean asthma?
- Night cough can occur with asthma but also with other conditions. Repeated night symptoms deserve a clinical assessment rather than a self-diagnosis.
