What should you know about a cough following croup?

Croup causes swelling around the upper airway, often producing a barking cough and a hoarse voice. Even after the noisy episode improves, irritation can leave a cough for a while. A cough that is gradually easing is different from stridor, a harsh sound while breathing in, or a cough that returns with worsening hoarseness. Another infection can follow, and children with asthma or bronchiolitis may need a separate assessment. The lingering cough alone does not show that croup has returned.

Keep the child calm and upright, because crying can make upper-airway noise more noticeable. Offer frequent drinks and check breathing when the child is settled and asleep. Use medicines prescribed for that croup episode exactly as directed, and do not use steam or give cough medicines unless a clinician recommends them. Avoid smoke and strong fragrances. Note whether the cough is improving, whether fever has returned, and whether the child is eating, drinking, and urinating normally.

Seek emergency care for stridor while resting, ribs pulling in with breaths, pauses in breathing, blue or grey lips, drooling with difficulty swallowing, unusual drowsiness, or inability to drink. Arrange prompt review if the barking cough worsens again, fever returns after improvement, breathing becomes faster, or the child is tiring. Infants and children with known airway or lung conditions may need a lower threshold for assessment.

Ask how to recognise stridor at rest, which medicine plan to follow if symptoms recur, and where to seek help after hours. Explain what the original episode sounded like, what treatment was given, and how the cough has changed.
