The presence of a fever that does not go away needs to be treated quickly. First of all, for adults, if the fever is high, more than 38.5 degrees, you can use ibuprofen suspension for antipyretic treatment, which often needs to be taken orally. Indomethacin suppositories or antipyretic suppositories, which can be inserted into the patient’s anus to reduce fever, are also effective. Secondly, if a child has a fever that is higher than 38.5 degrees or 39 degrees, convulsions are likely to occur, and oral ibuprofen suspension, acetaminophen suspension, or acetaminophen granules are recommended for antipyretic treatment. In addition, it is best to combine physical cooling methods, which can prolong the effect of antipyretic drugs, reduce the use of antipyretic drugs. For example, you can put a fever-reducing patch on the forehead, or use a warm towel to wipe the child’s skin all over the body, the effect of fever reduction is also relatively good. Especially in the armpits, groin and neck, where large blood vessels are more abundant, the wiping time can be slightly longer.
