Devez-vous donner des analgésiques aux enfants ?

Les deux paracétamol et ibuprofène are safe and effective antalgiques for the vast majority of children when they aren't feeling well. Paracetamol can be given from two months, as long as they were born after 37 weeks and weigh more than four kilograms, and ibuprofen can be given from three months, provided the child weighs more than five kilos.

If your child has a mild illness where they are distressed, uncomfortable or in a significant amount of pain, Dr Rohini Bajaj, consultant paediatrician at the Royal Manchester Children's Hospital and member of the Royal College of Paediatrics and Child Health, recommends giving paracetamol or ibuprofen. "This would be with or without a temperature," she says.

If your child has a fièvre, it may be tempting to reduce it by giving them paracetamol or ibuprofen. But if your child is otherwise happy and comfortable, there's no reason to give it, explains Bajaj. “We are now going with the attitude that if a fever is not causing the child any distress, we would not give anything and let the temperature come down itself.”

A fever is one of the ways that the body's immune system fights an infection. If a child is otherwise well with it, bringing a temperature down is not going to do anything, she says. "Of course, if your child feels unwell, distressed or in pain, we would advise you to use painkillers. And if the child is under three months of age, I'd advise they see a doctor."

There are some instances where you should seek further help by seeing your GP, contacting an advice service like NHS 111 (if in the UK) or going to A&E, if it's an emergency. According to Bajaj, the important signs to look for in your child include:

• Breathing very quickly.

• Putting a lot of effort into their breathing - so drawing in their ribs or top of neck.

• Somnolence ou incapacité à se réveiller.

• A rash that doesn't fade when you press on it.

• Refusing all fluids.

• A fever that has lasted five days or more.

Which painkiller should you use?

The painkiller you choose to give your child will depend on what's going on, says Dr Tim Ubhi, consultant paediatrician and founder of the Children’s e-Hospital.

"Problems such as toothache, or where there is a lot of inflammation, respond well to ibuprofen. Simple colds with low-grade fever can be managed with paracetamol," says Ubhi.

Paracetamol is now recommended when your baby is given the meningitis B vaccination at eight and 16 weeks because there is a high risk of developing a fever.

Never give your child both painkillers at the same time though. However, it's possible to alternate them if your baby's symptoms come back before the next dose. Ubhi explains: "For a mild illness, we usually recommend starting with paracetamol and then if needed add ibuprofen after an hour."

Children under 16 years should never be given aspirine, according to Bajaj. "There's a risk of a serious but rare condition called Reye's syndrome, which basically causes brain and liver damage," she says.

She also recommends avoiding codéine in children. "Codeine gets broken down into morphine and in some children, they're at risk of breaking it down too quickly and you get a kind of toxic effect. The most serious toxic effect is respiratory depression, where you will stop breathing.

"The advice at the moment is that you can use it in over-12s cautiously, and only if paracetamol and ibuprofen haven’t worked. It's important that it isn't used in children under 18 if they have had their tonsils or adenoids removed for a condition called l'apnée du sommeil, a condition where they stop breathing at night."

It's natural for parents to worry about using painkillers in children. "Each painkiller has got its own side-effects and problems if you reach a toxic level. So, with paracetamol, if you give too much, it can cause liver damage and in rare cases kidney failure as well. But this is only if you're going over the recommended dose."

Always check the manufacturer's guidelines and make sure you don't give your child another medicine with paracetamol in it as there is a risk of overdose.

Ibuprofen can also have side-effects. "It can cause inflammation to your child's stomach lining and should not be given when your child has varicelle because it may lead to an increased risk of serious skin infection - a condition called fasciite nécrosante," says Bajaj.

She adds that your child shouldn’t take Ibuprofen if he or she has asthma either - because it can cause problems with the airways as well as liver or kidney problems.

In rare cases, your child may have an réaction allergique to paracetamol or ibuprofen. If you notice symptoms of an allergic reaction, including wheezing, a skin rash, tightness in the chest or throat and swelling of the face, mouth or lips, take your child immediately to A&E or call an ambulance.
