Emergency department advice for the care of children with fever
What is fever?
Normal body temperature is around 37 degrees Celsius. A raised body temperature is often a sign of infection and is common in children when they are unwell.
A fever is a raised temperature of 38 degrees Celsius or higher and is best measured using a digital thermometer if possible.
Your child may feel hot and sweaty and look shivery and flushed. Fever is the body’s normal response to fighting an infection.
Infections caused by viruses are more common than bacterial infections. Viruses often also cause a runny nose, cough or sore throat. Viruses get better on their own and don’t need antibiotics.
The temperature usually returns to normal within 3 to 4 days.
Fever is common after vaccinations in the first 1 to 2 days.
What can I do to help my child?
- Offer and encourage regular fluids
- Do not over or under dress your child
- Give paracetamol (if over 3 months of age) or ibuprofen (if over 6 months of age) if your child is distressed or unwell.
Do not give both paracetamol or ibuprofen at the same time but consider the other medicine if your child does not respond to the first medicine after 30 to 60 minutes.
- Paracetamol (Calpol) can be given every 4 hours
- Do not give more than 4 doses in 24 hours
- Ibuprofen can be given every 6 hours
- Do not give more than 3 doses in 24 hours
- Follow the dosing instructions on the bottle of your medicine – the doses change as children get older, so make sure you are giving the right amount.
- More information on paracetamol and ibuprofen can be found here: Paracetamol and Ibuprofen.
- Keep your child away from school or nursery while unwell
- The latest NHS guidance related to COVID-19 for children is at NHS.uk Coronavirus symptoms in children
- Check on your child regularly
When should I worry?

- develops a rash that does not disappear with pressure (see the Glass Test below)

⚠️Go to the nearest hospital emergency (A&E) department or phone 999.⚠️
If your child has any of the following:
- is finding it hard to breathe
- seems dehydrated (sunken eyes, drowsy or not had a wee or wet nappy for 12 hours)

You need to contact a doctor or nurse today
Please ring your GP surgery or call NHS 111.
If none of the above are present:
Using the advice above you can provide the care your child needs at home.

A rash that doesn’t fade when a glass is pressed firmly on the skin is more worrying. Seek medical advice urgently.
