What should you know about post viral cough treatment?

After a virus, the airway lining may remain sensitive and react to talking, cool air, exertion, smoke, or mucus from the nose. A cough can therefore continue even when fever and congestion have settled. Treatment depends on the pattern: wheeze may lead to an asthma assessment, nasal symptoms may suggest allergic rhinitis, and a sour taste or night cough may point towards acid reflux. Persistent cough also needs consideration of acute bronchitis or chronic cough rather than repeated self-treatment.

Sip fluids, soothe the throat with a warm drink, avoid tobacco smoke and strong scents, and rest between activities. Honey can reduce throat irritation in people over one year old. Use only medicines recommended for your age, health conditions, and other medicines. Antibiotics do not treat a viral cough, and inhalers or reflux medicines should be used when a clinician has identified a reason for them. Keep a simple record of triggers, sleep disruption, mucus, wheeze, and breathlessness.

Get urgent help for severe breathing difficulty, chest pain, coughing blood, fainting, confusion, or blue or grey lips. Book a review when the cough is worsening, interrupts sleep, restricts activity, or fails to improve. Earlier assessment is sensible for young children, older adults, pregnancy, or existing lung disease.

Ask which cause best fits your cough, whether you need a chest examination or breathing test, which treatment is appropriate, and when to stop or review it.
