My son is 13months old, he has been having fever at night and early morning ranging between 100 to 103.5F, whenever I give P125 the temp reduces to normal, no ear infection or throat infection, has reduced appetite only drinks milk for the last 5days, Dr suggested to give Zifi Antibiotic (Cefixime Oral suspension 50mg/5ml), so we have given this twice daily last 3days, fever still comes in night and morning, otherwise he is playing and active during day, when fever shoots up he is quite, he has had two canine teeth coming up, no other symptoms, please suggest
