Hello
Let me explain about the drugs which you are giving your son.
Crocin is
paracetamol ( anti pyretic or for fever ) , combiflame is ibuprofen + paracetamol ) .
Meftal P is mefeanic acid tablet and its dose is 25 mg / kg body weight in divided dosage ( two or three times in day ) .
Mainly ( mefanic acid ) is used in
Rheumatoid arthritis , moderate to severe pain, osteoarhritis . Few doctors also use it in fever .
As you mentioned that your son is having fever with
sore throat and cold , so when such type of patient visit in my clinic I advise them to take
LEVOFLOXACIN 15 mg / kg body weight tablet once in day after meal for 5- 7 days .
I also advise my patient to take local anti septic lonzges for sore throat.
Please get in blood for C B C, E S R , Widal test (
typhoid fever).
Since this is a prescription medicine so consult a physician and get his opinion.
Good luck.
