question: My son started a fever at around 1:00PM IST and it had reached 103.5. He was given Tylenol and Advil alternated every 3 hours. He was taken to a pediatrician in Trivandrum India who advised he be given Meftal P (Mefanamic Acid Suspension) instead of Ibuprofin. His temp now is at 101.9 and he has chills/shivering. How long should we wait before Meftal is given to him as he Advil was given at 11:30 PM and the time now is 3:00 AM. He is 4.5 years old and 3.5 feet tall and weighs 43 Lbs
