<s>[INST] Hi, my child is 5 year old and once in a month he suffers from tonsillitis problem, the day I notice his fever and pain while swallowing issues i give him Arithral 200mg syrup. Is it fine to give antibiotic the very first day of his fever or I should wait for 1 or 2 days?, also how can I reduce his tonsilitis issue that comes every month? [/INST] Hi.this age tonsillitis occurring so frequently is uncommon. I am trying to say that it is so uncommon that we should think whether it is really tonsillitis and reconsider the diagnosis. You are right - we should not be using antibiotics so frequently. Using an antibiotic after a bacteriological evidence is prudent, and it can be done by a throat swab culture or a rapid antigen test. 95% of kids illness of sore throat in this age group are viral, and they do not warrant antibiotic usage.Sometimes warm saline gargles will help a lot in preventing such recurrences.
