What should you know about inhaler for shortness of breath?

A reliever inhaler can help when airway narrowing is involved, such as in Asthma or COPD. It will not treat every cause of breathlessness. Acute Bronchitis, Anaemia, heart conditions such as Angina or Atrial Fibrillation, Bronchiectasis, and a severe allergic reaction can need different care. New, unexplained, or recurring breathlessness should therefore not be managed by borrowing someone else’s inhaler.

If an inhaler has been prescribed, follow its label and your action plan. Sit upright, use the demonstrated technique, and note whether breathing improves. A spacer may help with some pressurised devices. Avoid repeating doses beyond the plan, and arrange assessment if relief is brief or incomplete. Keep a record of triggers, timing, cough, wheeze, fever, palpitations, and activity-related symptoms to help identify the cause.

Call emergency services for sudden severe breathlessness, swelling of the lips or tongue, fainting, confusion, blue or grey lips, crushing or spreading chest pain, or inability to speak in full sentences. Urgent medical advice is also needed when breathlessness begins after a new medicine or sting, worsens quickly, or does not respond to your prescribed plan.

Ask whether your symptoms fit an airway problem, which inhaler is appropriate, how to use it, and which warning signs mean you should seek emergency help rather than take another dose.
