Fevers are common in young children, especially if they have a chest infection or after a vaccination. A fever (a temperature of 37.8°C or higher) doesn’t necessarily mean you or your child has a serious illness. In fact, a fever helps the body’s immune system to fight infection.

People often want to give their child medicine, such as paracetamol or ibuprofen, to bring down the fever. This is not necessary, unless your child is distressed.
A fever is the body’s normal response to an infection, and fever can help slow the growth and spread of bacteria. So fever is a sign that your child’s immune system is doing its job – there is no need to try to bring down the fever.
If your child is in pain or is distressed, then painkillers can help them feel better. So if your child has a fever but is playing and happy, there is no need to give them paracetamol or ibuprofen. If your child has a fever and is miserable, paracetamol or ibuprofen can help.
A fever does not mean your child needs antibiotics.
For these reasons, antibiotics shouldn’t be given unless your child has a bacterial infection.
Sometimes, children with fever may have a fit or seizure because of the fever. This is called a “febrile convulsion”. Medicine to bring down a fever, such as paracetamol and ibuprofen, does not help to reduce the chance of your child having this type of complication.
