I am not a medical professional and you should call 111 for advice.
BUT below is the info from NICE guidance on feverish illness in children. Snapshot is
- don't be too concerned about the temperature, look at his overall condition. - If calpol doesn't make him feel better then try ibuprofen instead; you can alternate between the two.
- give hm plenty to drink and check carefully for signs of dehydration; also for signs of difficulty in breathing ( look at his chest and tummy)
- if you are worried call 111
NICE guidance CG160 (home care bit)
- Antipyretic agents do not prevent febrile convulsions and should not be used specifically for this purpose. [2007]
- Tepid sponging is not recommended for the treatment of fever. [2007]
- Children with fever should not be underdressed or over-wrapped. [2007]
- Consider using either paracetamol or ibuprofen in children with fever who appear distressed. [new 2013]
- Do not use antipyretic agents with the sole aim of reducing body temperature in children with fever. [new 2013]
- When using paracetamol or ibuprofen in children with fever:
continue only as long as the child appears distressed
consider changing to the other agent if the child's distress is not alleviated
do not give both agents simultaneously
only consider alternating these agents if the distress persists or recurs before the next dose is due. [new 2013]
