<s>[INST] My son has very high fever. He is 4 years old and has been having fever for the past two days..last night was bad as his fever went upto 103.6f . I gave P125 which didnt work. so gave a towel bath and gave ibugesic plus 8 ml(he weighs 13.4kgs). Now he is fine. but not sure how long and frequently i can give ibugesic. He also had shaking chills last night . We have been giving him an antibiotic that the doctor prescribed for the past 2 days...to be given for 3 more days.. Why did he get shivering chills..why is the fever not responding to normal paracetemal. how much more should i give this ibugesic, is it safe for a 4 year old kid? [/INST] Hello, Your baby is probably suffering with viral fever; it is associated with shivering when fever is high. High grade fever does not respond to paracetamol syrup alone; it requires combination medication. Syrup Eugenic plus can be given 6 to 8 hourly, minimum 4 hour intervals between 2 doses. High grade fever will probably persist for 1 to 2 more days. Then you may shift to Paracetamol syrup. All medication discussed here are safe for child Chat Doctor. Hope I have answered your query. Let me know if I can assist you further. </s>
