<s>[INST] Hi MY son is 10.6 year old and has fever 101 but Paracetamol 250 is not improving the situation even after 2 hrs i mean fever is not coming down so Meftal P is the other option ... need to know the permissible time Gap in dosage between Paracetamol and Meftal P .... His weight is 25.6 KG [/INST] Hello, You are giving very little paracetamol to your son. At this age he should be taking 500 mg up to 4 times a day (every 6 hours) and not 250 mg. Give your son the right dose of paracetamol, and he will be fine. Do not use metal medicine for your son as he is too young for that. You can give him Ibuprofen instead, 400 mg every 8 hours, always in alternation with paracetamol, if paracetamol alone will not do the work. For example, If you give paracetamol at 14 o'clock (2 p.m.) and the fever is high (next dose of paracetamol will be at 20:00), then you can give ibuprofen at 16:00 (next dose of ibuprofen will be at 24:00) and so on until the fever will be dominated. Hope I have answered your query. Let me know if I can assist you further. </s>
