Croup
Croup is a common childhood illness that can cause a distinctive, bark-like cough. It can also cause difficulty breathing which can be frightening for both you and your child.
Croup is caused by a virus which affects the airways including the voice box (larynx), windpipe (trachea) and lungs (the bronchi) causing them to swell and become narrower.
Some children have croup two or more times in their childhood.

What are the symptoms of croup?
- A cough. The cough is usually harsh and barking. This ‘croupy cough’ is due to inflammation and swelling of the vocal cords in the voice box (larynx).
- Noisy breathing. The infection can narrow the voice box (larynx) and windpipe (trachea) and cause an extra noise called a stridor. This noise is normally heard on breathing in.
- Breathing may become difficult if the narrowing becomes worse.
- Your child may also have a runny nose, hoarse voice, sore throat, high temperature (fever), general aches and pains and be off their food. Croup may follow a cold but can also appear without any earlier illness.
- The symptoms of croup appear worse at night. A mild but irritating cough may persist for a further week or so.
How can I help my child?
- Stay calm. This will help keep your child calm. Children with croup may become upset. Crying may make their symptoms worse.
- Sit your child upright on your lap if their breathing is noisy or difficult. Let them find the most comfortable position.
- Encourage your child to drink cool drinks regularly (little and often) to help soothe their throat and keep them hydrated.
- If your child seems to be in pain or discomfort, you can give your child Paracetamol or Ibuprofen, following the instructions on the container.
- If their temperature is high, dress them in cool, loose clothes (if any) and don’t use anything warmer than a sheet to cover them in bed.
- Stay with your child or check him or her regularly. You need to know if the symptoms are getting worse.
- Some people find that taking their child outside in the cool, fresh air helps to relieve their symptoms
- There is no evidence that steam inhalation helps. There is a risk of scalds if steam is used.
- Do not give cough syrup. It is not recommended for children under 6 years. It can make children sleepy and does not help croup.
How is croup treated?
- Your child may be given a steroid medicine called dexamethasone or prednisolone which can reduce airway swelling
- As croup is caused by a viral illness antibiotics are not needed.
