First the dose had to be adequate. 1ml of P 125 is only 25 mg. For a 10 kg child dose is 150 mg or 6ml of P 125 which u can repeat maximum 4 times in a a day . Check The concentrations of the preparation u have. Above dose is only for preparation with 125mg in 5ml
Secondly, sometimes it can take long in a child for the fever to settle. So u can remove babies all clothes and keep open below a low fan. May be give a bath with normal water but dry immediately.
But in a small less than 3 month baby u should consult your doctor
Take care
Next Steps
