Hi...Thank you for consulting in Health Care magic.
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 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 15mg/kg/dose (maximum ceiling dose of 500mg) every 4-6th hourly that too only if fever is more than 100F. I suggest not using combination medicines for fever, especially with Paracetamol.
Cough and cold are viral 95% of the times in children. For cold you can use anti-allergics like
cetirizine and for nose block, saline nasal decongestants will do. For cold you can use
Cetrizine at 0.25mg/kg/dose every 12 hourly for 3 days.
For nasal block, plain saline nasal drops will do, every 4-6th hourly to relive
nasal congestion.
