Wet cough treatment

A wet cough may reflect a short-lived viral infection, acute bronchitis, post-nasal drainage, asthma, reflux, or a long-term airway condition. A clinician considers how long it has lasted, the mucus, temperature, breathing, chest sounds, smoking history, and existing illness. Tests are considered when the examination or symptom pattern suggests they could change management.

Antibiotics do not treat viruses and are not automatically useful for a mucus-producing cough. Asthma-related cough may need inhaled treatment, while reflux or nasal allergy requires a different approach.

Drink enough fluid to avoid dehydration, rest, and avoid smoke, vaping, and dusty air. Use prescribed inhalers exactly as directed, and do not borrow another person’s inhaler. A pharmacist can check whether an over-the-counter product is safe with your age, pregnancy status, allergies, and regular medicines. Seek review if the cough keeps returning or limits sleep and normal activity.

Seek urgent care for severe difficulty breathing, blue or grey lips, confusion, fainting, coughing blood, or persistent chest pressure. Contact a clinician promptly for worsening breathlessness, dehydration, high fever with marked illness, or a cough that is not improving. People with asthma or bronchiectasis should follow their personalised action plan and seek advice when control changes.

Ask what cause is being considered, whether you need a chest examination or testing, and how long to try the recommended treatment. Clarify which symptoms should trigger an earlier review and whether any current medicine may be contributing.
