Dry cough remedies: what can help?

A dry cough produces little or no mucus. It can follow a viral cold, arise when nasal drainage irritates the throat, or be triggered by smoke, dust, perfume, or dry air. Reflux can irritate the throat, while asthma can cause cough with chest tightness or wheezing. A cough that keeps returning deserves a review because chronic cough, bronchiectasis, or another airway problem may need targeted treatment.

Sip warm fluids, use honey if suitable for you, and keep water nearby. Avoid smoking, vaping, incense, and known airborne triggers. Moistening the room and resting your voice may reduce throat irritation. Saline nasal treatment can help when congestion or drainage is contributing. A pharmacist can explain whether an over-the-counter product is appropriate, especially if you take regular medicines, are pregnant, or are treating a child. Do not start antibiotics for a simple cough unless a clinician prescribes them.

Arrange medical advice if the cough is persistent, repeatedly interrupts sleep, or comes with fever, wheezing, breathlessness, chest pain, weight loss, or blood. Seek urgent help for severe breathing difficulty, blue or grey lips, confusion, or sudden chest pain. A clinician may listen to your chest and review medicines, reflux, allergies, and exposure to irritants.
