### output:

Hi... Thank you for consulting in Chat Doctor. Fever of few days without any localizing signs could as well a viral illness. Usually rather than fever, what is more important is the activity of the child, in between 2 fever episodes on the same day. If the kid is active and playing around when there is no fever, it is probably viral illness and it doesn't require antibiotics (Like Cefprozil) at all. Once viral fever comes it will there for 4-7 days. So do not worry about duration if the kid is active. Paracetamol can be given in the dose of 15 mg/kg/dose (maximum ceiling dose of 500 mg) every 4-6th hourly that too only if fever is more than 100F. I suggest not using combination medicines for fever, especially with Paracetamol. Mefenamic acid is a NSAID. It carries the risk of gastritis and renal problems in the long run. Please do not use Metonymic acid. Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
