In children with fever caused by viral infections, treatment for viral infections can often reduce the fever. If it is a common viral infection, it is better to take antipyretic drugs for treatment. In case of viral fever caused by influenza virus, the effect of taking the above antiviral drugs is often not enough, and the child can be given oseltamivir for antiviral treatment. If the temperature of the fever is high, in addition to antiviral drugs, antipyretic drugs are also needed, especially if the temperature is greater than 38.5 degrees, children need to be given oral ibuprofen suspension or acetaminophen suspension for fever reduction treatment. In case of recurrent high fever, the medication can be repeated once for the child at an interval of 4 hours or more than 6 hours.
