Wheen starting antibiotics, it typically takes 24 to 48 hours to see an improvement, and they only work if the infection is bacterial, not viral. Crocin (paracetamol) helps temporarily lower the temperature but does not cure the infection itself, so the fever may return as the medication wears off. This is a normal part of the body fighting the illness. For now, focus on keeping him comfortable and well-hydrated. Please consult his pediatrician if the fever lasts beyond three days, or if you notice warning signs like extreme lethargy, difficulty breathing, or poor fluid intake.
