How effective is inhaler therapy for asthma?

Reliever inhalers can ease wheeze, cough, and chest tightness by relaxing airway muscle. Preventer inhalers reduce inflammation and are taken regularly, even when symptoms are quiet. Improvement depends on the asthma pattern, triggers, medicine choice, and inhaler technique. Needing a reliever more often, waking at night, or limiting activity can mean the treatment plan needs review rather than simply more doses.

Use the inhaler exactly as prescribed and ask a clinician or pharmacist to watch your technique. A spacer may help some people use a metered-dose inhaler. Keep a record of symptoms, reliever use, and triggers. Rinse your mouth after an inhaled steroid if instructed, and do not stop a regular preventer without medical advice.

Follow your written asthma action plan during worsening symptoms. Seek urgent help if breathing is very difficult, speaking is hard, lips look blue or grey, or a reliever is not helping. Arrange a review after an attack, repeated night symptoms, or a persistent cough so the diagnosis and treatment can be checked.

Ask which inhaler is for immediate relief, which prevents symptoms, how to use each device, whether a spacer is suitable, and when your treatment should be reassessed.
