by Priya Chatterjee

duration

3-5 days typically, worst on night 2-3

common age

6 months to 3 years

symptoms

  • barking cough (sounds like a seal)
  • hoarse voice
  • stridor (harsh breathing sound when breathing in)
  • symptoms usually much worse at night
  • runny nose and mild fever before cough starts
  • symptoms often improve during the day and return at night

when to see a doctor

see your GP or call 13 HEALTH (13 43 25 84) if:

  • stridor when resting (not just when crying or upset)
  • difficulty breathing or rapid breathing
  • skin around the neck or ribs sucking in with each breath
  • drooling or difficulty swallowing
  • fever above 39degC that does not come down with paracetamol
  • your child has had croup before and it seems worse this time

when to call 000

call 000 immediately if:

  • your child is very pale or blue around lips or fingernails
  • your child is struggling to breathe — chest and neck sucking in deeply
  • your child is unusually sleepy, hard to wake, or floppy
  • your child is drooling and cannot swallow — may indicate epiglottitis
  • stridor is getting worse, not better

home treatment

  • keep your child calm — crying and distress make symptoms worse
  • sit your child upright or hold them in your lap
  • cool night air can ease symptoms — try standing near an open window or stepping outside briefly
  • give paracetamol or ibuprofen for fever and discomfort
  • offer small sips of fluid regularly
  • stay with your child and monitor breathing
  • your GP may prescribe oral steroids (prednisolone/dexamethasone) which reduce swelling quickly
  • steam from a hot shower has NOT been proven to help but some parents find it soothing

prevention

  • croup is caused by common viruses — regular handwashing helps
  • keep immunisations up to date
  • avoid contact with people who have colds where possible
  • there is no specific vaccine for croup
