Croup in Children — Ireland Parent Guide
How to recognise croup, what helps at home, and when ED is needed.
What croup is
Croup is a viral infection that causes swelling around the voice box, leading to a distinctive “barking” cough, hoarseness, and sometimes stridor (a high-pitched noise on breathing in). Most common in children aged 6 months to 3 years.
Typical course
Symptoms are usually worst at night, often suddenly, and improve over 3–5 days. Most children recover at home.
What helps at home
- Stay calm — crying makes the airway swelling worse
- Sit your child upright in your arms
- Cool air or steamy bathroom — both can help (limited evidence; comfort works either way)
- Paracetamol or ibuprofen for fever / discomfort (weight-based)
What an Online Doctor can do
An IMC-registered Online Doctor can assess by video, prescribe a single dose of dexamethasone for moderate cases (very effective at reducing airway swelling), and explain red flags. Most children with mild croup do well with no treatment beyond reassurance.
When to attend ED
Call 112/999 or attend ED if your child:
- Has stridor at rest (not just when crying)
- Is struggling to breathe — chest indrawing, fast breathing, can’t finish sentences
- Has blue or pale lips
- Is unusually drowsy or floppy
- Is drooling or unable to swallow saliva

The viruses that cause it are spread by droplets — yes.
Can my child go to creche?
Once fever has settled and breathing is normal.
When can dexamethasone help?
In moderate-to-severe croup; less benefit in very mild cases.
