<s>[INST] Our Son (2 yrs) is getting fever in night with shiverining at times (past 2 days) . Fever is rsing in evening and in midle of night he also shivers. We are giving paracetamol for fever. Why he is getting fever with shivering only in night? Is our medication correct? Should we take him to paeditrician right away? [/INST] Hello, Shivering during high fever is common. Fever of a 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 a viral illness and it doesn't require antibiotics at all. Once the viral fever comes it will there for 4-7 days.  So do not worry about the 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. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  </s>
