You have not mentioned the age and weight of your daughter.
For fever, since you have already started Ibugesic
plus, continue giving it in right dosage every 8 hrs.
can be a part of viral illness. If she keeps vomiting, she might need other medicines like Domperidone
For any fever the safest medicine is Acetaminophen
alone given in dosage of 15mg/kg/dose given 4 times a day.
If head ache is severe and vomiting continues, you must see the Pediatrician
Just keep a watch on her general activity also. If she is tired and lethargic, she needs to be examined by a doctor.
Hope my answer helps you.
Wish a speedy recovery for your daughter.
