Should You Give Paracetamol to a Baby with a Fever?

Waking up to a crying baby and finding out they are in fever is a frightening idea for new parents. Newborns can develop a higher body temperature more often than adults as they have not developed the functions used to regulate their temperature yet. And while most fevers are a non-dangerous sign of the baby’s immune system fighting an infection, they can make your little one feel uncomfortable for a couple of days.

Here’s what to do when your baby has a fever in Hong Kong.

What is considered a fever for infants?

Generally, a high body temperature above 38 degrees Celsius is considered a fever in a baby. There are small differences between measuring the temperature using different types of thermometers, so you should double-check the specific threshold below:

Armpit thermometer

38 °C

Oral thermometer

37.7 °C

Rectal thermometer

37 °C

 

While any of these will give you a reliable estimation of your infant’s temperature, it is generally recommended to use the rectal thermometer for best accuracy. 

 

What to do when your baby has a fever

First of all, do not panic. While it is commonly believed that a high fever can cause brain damage among babies and toddlers, this doesn’t happen under normal circumstances. Cool bathing is also generally not recommended despite conventional wisdom and can make the fever worse as a result.

When it comes to medication, you can give paracetamol (acetaminophen) to babies from 3 months old, and ibuprofen from 6 months. You should definitely offer more fluids to your child as they are more likely to become dehydrated when experiencing a fever.

Your baby’s body temperature is also likely to increase due to non-fever related factors, such as teething, sitting out in the sun, or extended crying. An infant’s body has a weaker ability to self-regulate its temperature, so it may increase or fall a little due to many everyday situations – it’s best to wait for at least an hour before giving your child fever medication – unless there are strong signs of discomfort.

When to call a doctor 

In most cases, there is no need to seek immediate medical help for a fever – but you can use your child’s behaviour as a guideline. If your child is behaving normally, then you can keep observing them and give medication and apply other home-made remedies as necessary to minimise the discomfort.

 

If in doubt, you can ask yourself the following questions:

  • How old is your child? Children below the age of 12 months are more likely to experience seizures due to fever, so it is good to inform your family doctor about the situation as soon as possible.
  • How long has your child been in a fever? The longer the fever, the more serious the underlying source of fever may be, so you should not wait longer than 3 days to seek medical care, even if the child is behaving normally.
  • What are the other symptoms? Vomiting, diarrhoea, and tearless crying are all serious symptoms that should be reported to the emergency medical care unit immediately – it is best to call your doctor or 999 in case you can’t reach your clinic.

 

Before consulting a doctor, you should prepare yourself to answer the following questions:

  • Symptoms 
  • Medical history
  • Home remedies or medications that were given
  • Changes to the baby’s eating pattern or bowel movements
  • Possible exposure to other sick people / crowded areas

 

Fevers can also cause febrile seizures in infants – these are usually not serious and do not cause any brain damage. However, if your child is showing symptoms of a seizure for longer than 15 minutes – not moving and/or passing out – you should call 999 immediately.
