How long does it take for Augmentin 375 to start working for a sinus infection, and is it normal that my son's fever has still not gone down after four days?

Asked by Female, 10 · 1 month ago

Normally, amoxicillin/clavulanate (Augmentin) starts to work within 48 to 72 hours. Because his fever has persisted for four days, it is highly recommended to contact his pediatrician today. The doctor may need to re-evaluate him to see if he needs a different dosage, a different medication, or if the illness is viral. Please rest assured that getting him checked will help get him on the right track to recovery.
