For a 10 kg baby, Zifi 50 (cefixime) is typically given as 4 ml twice daily, usually for 5 days, but this antibiotic must only be started under a doctor's guidance. Meftal P (mefenamic acid) is usually given as 2 ml to 2.5 ml up to three times a day, strictly as needed for high fever (with a 6 to 8-hour gap), and not on an empty stomach. Please consult your pediatrician before administering these medications to ensure the exact diagnosis and safe dosing for your baby.
