Fever and Cold to My Son - Any Antibioti

Dear Sir / Madam, My Son Name is K. SaiRaghav, Age: 7.11Yrs, Height: 128CM. For the last 3 days My son was not fine due to Cold and Cough. From Yesterday Afternoon at 02.30pm onwards Fever started and it was 101 so given P250 6.5 ml given but not reduced and Again @ 06.30pm P250 given it was 101 only. So immediately we took him to Hospital and Paediatric Doctor advised to Take MEFTAL P 6 ML - 6 Hours once for 1 day. Montair LC KID TABLET - Once @Night, Ascoril LS - 1-1-1 - 5ml for 3 days. If Fever Persists P250 6ml 3 times for 3 days. My question is: 1. Any Antibiotics is required? 2. From the last year When the School has started after Covid  every 2 to 3 months he will be sick like this. After giving Antibiotics only he seems to be fine Not only him, Many of the school mate was been like this.. 3. More than 3 times he has taken Antibiotics in an year. Plz advise... Looking out for all your support in this regard.
