<s>[INST] my child is 5+ years of age with wt approx21 kg+. at present he is suffering from fever ( can t diagonised the reason) and temp reduces from 103 degree to 102.5 after applying crocin ds 5ml almost an hr ago, seeking your suggestions in this respect please. [/INST] Hello and welcome to Chat Doctor. Fever can be due to a viral or bacterial infection.It's very common to get flu in childhood. Since when he is having fever?.generally a fever caused by viral infection subsides within 5-7 days. There is no need to give any antibiotic for that. Just paracetamol can be given for fever. But fever persists more than that it can be due to other cause which needs antibiotics and some investigations. Hope this answer helps. Take care. Regards </s>
