Does my child need ibuprofen?
- Ibuprofen may be used if your child needs pain relief or if your child has a fever (temperature over 38.5°C) and is miserable.

Ibuprofen should start to work quite quickly. Your child should feel less pain 20–30 minutes after taking ibuprofen.
- Use ibuprofen only if necessary, and for the shortest period of time to reduce fever or pain.
- It is important to see a doctor if your child needs to take ibuprofen for more than 2 days, or if it is not working.
- For some types of long-term inflammation and pain such as arthritis, your child will need to take ibuprofen regularly.
