What are the other symptoms she has?
, loose stools, urinary problems?
is a symptomatic medicine that just brings down the temperature and gives comfort to the child. For simple viral fevers, paracetamol alone would be enough.
If symptoms and examination findings are suggestive of a bacterial infection, antibiotics will be needed accordingly.
Along with fever if activity of the child and feeding are not good, it is a must to see a pediatrician
as its already 3 days of fever now.
Hope my answer helps you!
