How does the child have a fever 40.3 degrees to do

The child has a fever of 40.3 degrees, which is already a high fever. First of all, it is necessary to take it in time. Acetaminophen or ibuprofen suspension and other antipyretic drugs help to reduce fever. At the same time, some physical methods should be taken to help cool down, such as warm water wiping the child's body, sticking antipyretic patches, cold compresses, alcohol wiping armpits, etc. If the child does not return to high fever or repeated high fever after taking antipyretic drugs, he should take the child to the hospital in time.
