Dear Sir/ Madam, Thank you for posting your query at healthcaremagic.com Usually some of the kids at this age active if they fever. As the fever is coming back repeadly I advice you to give him first paracetamol as it potent anti febrile medicine. If the fever is back with in 4 hours than give Ibugesic other wise continue paracetamol every six hourly. Meanwhile, I strongly suggest to get his blood and urin analysis done to rule out any chronic infection is persisting, as you mention that it** reoccurs after 4 days** and let the pediatrician examine him. Nourish him with lots fluids. Hope this is informative to you. Your thank you note is very much appreciated. Please revert back if you have any further query. with best wishes, Dr. Vishwanath Patil
