What should you know about instant cough relief?

Coughing clears mucus, dust, and other irritants from the airways. A common cold or acute bronchitis may cause a short-lived cough, while allergic rhinitis can cause throat drainage and irritation. Acid reflux may trigger coughing, particularly after meals or when lying down. Asthma, bronchiectasis, bronchiolitis, and chronic cough have different patterns and need different assessment. A cough by itself does not identify one particular condition.

Sip warm fluids, rest your voice, and use humidified air if it feels comfortable. Avoid cigarette smoke, vaping, perfume, dust, and other triggers. Honey may soothe an adult throat, but it must not be given to an infant. A pharmacist can advise about cough products, interactions, and age restrictions; antibiotics do not treat every cough. If reflux seems related, smaller meals and staying upright after eating may help while you arrange advice.

Get urgent help for severe breathing difficulty, blue or grey lips, chest pain, confusion, coughing blood, or a rapidly worsening cough. Arrange medical review for wheezing, fever that persists, breathlessness with activity, repeated night-time cough, or a cough that continues beyond the expected recovery from an infection. Children, older adults, and people with lung or heart disease may need earlier assessment.

Could this be reflux, allergy, asthma, infection, or a medicine effect? Do I need an inhaler or examination? Which over-the-counter product is safe with my current medicines? What change in breathing should prompt urgent help?
