Cold cough home remedies: what helps and when to seek care

A cough can clear mucus and irritants from the airways. With a common cold, it may be dry or bring up mucus, and throat irritation from nasal drainage can keep it going after other symptoms improve. A cough can also occur with acid reflux, allergic rhinitis, asthma, or acute bronchitis, so the surrounding symptoms matter. A cough that continues or repeatedly returns deserves a clinical review, particularly if it affects sleep or daily activity.

Sip water or warm drinks regularly, use honey in a warm drink if suitable for you, and keep the air free from cigarette smoke, vaping and strong fragrances. Rest, raise your head slightly when sleeping, and consider saline nasal rinsing if post-nasal mucus irritates your throat. Follow the label for any pharmacy medicine and check with a pharmacist if you are pregnant, treating a child, or taking regular medicines. Antibiotics do not treat an uncomplicated viral cold.

Arrange medical advice for breathlessness, chest pain, coughing blood, a new wheeze, confusion, or a cough that is worsening rather than settling. Seek urgent help for severe difficulty breathing, blue or grey lips, or marked drowsiness. A clinician may need to assess persistent cough, fever, dehydration, or an underlying condition such as asthma or bronchiectasis.

Ask what may be triggering the cough, whether your chest needs examination, which medicines are appropriate for you, and what change should prompt a follow-up visit.
