What should you know about remedies for barking cough in adults?

A harsh, barking sound can occur when the throat or upper airway is irritated. A cold, acute bronchitis, allergies, asthma, acid reflux, or another airway problem may contribute. The sound alone cannot identify the cause. Notice whether the cough is dry or produces mucus, whether it began after a cold, and whether it is worse at night, with exercise, or around smoke and dust.

Sip warm fluids and keep the throat moist. Rest your voice, avoid smoking and second-hand smoke, and reduce exposure to strong fragrances, dust, and cold dry air. Honey in a warm drink may soothe an adult throat, but do not use it if it is unsuitable for you. Follow any existing inhaler plan exactly as prescribed. A pharmacist or clinician can help choose a cough product after checking other medicines and health conditions; avoid combining products with overlapping ingredients.

Get urgent help if you are struggling to breathe, cannot speak in full sentences, develop blue or grey lips, feel faint, or have sudden swelling of the face or throat. Seek prompt assessment for chest pain, coughing blood, a high or persistent fever, wheezing, or a cough that is worsening rather than settling. A cough lasting beyond the expected recovery period, returning repeatedly, or disturbing sleep deserves a clinical review.

Could my cough be related to reflux, allergy, asthma, or an infection? Do I need a chest examination or breathing test? Which medicines are safe with my current treatment? What changes should prompt urgent review?
