Dry cough relief: practical steps

A dry cough produces little or no phlegm and may follow a cold or acute bronchitis. Allergic rhinitis can cause drainage that tickles the throat. Acid reflux may irritate the throat after meals or when lying down. Asthma can cause cough with wheeze, chest tightness, or breathlessness; bronchiectasis more often involves recurrent infection or phlegm. Relief is more lasting when the cause is addressed, so note the pattern instead of treating every cough in the same way.

Take regular sips of water and use a warm drink if it feels soothing. Avoid smoking, vaping aerosols, dusty spaces, and strong fragrances. If reflux seems possible, avoid lying down soon after eating and ask a pharmacist or clinician about suitable treatment. A pharmacist can also check whether an over-the-counter product is safe with your medicines, pregnancy status, age, and health conditions. Do not use antibiotics unless prescribed after an assessment.

Book a GP appointment when the cough persists, returns frequently, affects sleep or activity, or comes with wheeze. Seek urgent help for severe breathing difficulty, chest pain, coughing blood, confusion, fainting, or rapidly worsening symptoms.
