### input:
My son has had high fever for about 10 days. He is 4 years old and weighs 20kg. He had a running nose a week before he got fever. In the initial few days fever was around 102-103 in the armpit. After about 3 days of fever we gave him an anitbiotic (azithral). The fever didnt get better. It would get better when we gave crocin or meftal. Now we are using another anitbiotic calle Keflor. In the last two days, when we give crocin or meftal, the fever stays down for about 9hrs and starts to come back. We are on day 3 of a 5-day keflor course. We are wondering if we should get a blood test done. He is not eating much.

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 Literal 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. Meftal contains Metonymic acid which is a NSAID. It carries the risk of gastritis and renal problems in the long run. Please do not use Metal. 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.
