A three-year-old child with recurrent fever of 39 degrees needs to be treated quickly with antipyretic drugs, otherwise the child is relatively small and for high temperature stimulation, it is easy to have high fever convulsions, which can cause damage to the child’s brain function. At this time, you can take oral ibuprofen suspension and acetaminophen suspension for the treatment of fever reduction. If the fever is repeated, the medication can be repeated once after an interval of 4-6 hours, and no more than four times a day. If the frequency of fever is more frequent, you can use ibuprofen suspension and acetaminophen suspension for cross-use, which can reduce the side effects of the drugs. It is best to combine physical cooling methods, which can reduce the use of antipyretic drugs and also prolong the duration of action of antipyretic drugs. It is recommended to use a warm towel to rub the baby’s skin all over the body, especially the armpits, groin, and neck, where large blood vessels are abundant, for a slightly longer period of time. It is also possible to replace the warm towel with alcohol, diluted white wine.
