Paracetamol for kids
Paracetamol tablets and soluble tablets contain 500mg of the active ingredient paracetamol. These tablets should not be given to anyone under the age of 10 years. For children between 10-15 years old, they can take 1 tablet every 4-6 hours.
For the treatment of pain and fevers in children under 10 years old, syrup or melt versions of paracetamol should be used.
What does paracetamol do and how does it work?
Paracetamol is thought to work directly on the central nervous system within the body, reducing the pain signals that can travel up the spinal cord and reach the brain.
It is also thought that paracetamol, like other painkillers such as ibuprofen, prevent the chemical prostaglandins being produced. Prostaglandins are naturally generated by the body as a result of pain and fever so by decreasing their production; paracetamol reduces pain sensations and the body’s temperature.
How long does paracetamol take to work and how long does it last for?
Paracetamol can take up to an hour to take effect but most people will notice some improvement to their pain and fever within half an hour.
Like all medicines, paracetamol starts to be broken down by the body as soon as it is swallowed. If you were to take one single dose of paracetamol, usually you will notice pain or a fever return within 4-6 hours.
If you are experiencing moderate pain which you are not able to tolerate with just paracetamol alone every 4-6 hours you may want to consider taking another pain killer alongside paracetamol such as ibuprofen or an opioid painkiller.
If you are unsure or would like further advice about what killers you should take you may want to take a look at our Pain page or speak to a doctor or pharmacist.
