The fastest way to reduce fever is to use antipyretic drugs. Antipyretic drugs can be divided into three types according to the method of administration: oral, suppository, and intramuscular injection. Oral antipyretic drugs include ibuprofen suspension, compound acetaminophen oral liquid, etc.; suppository antipyretic drugs mainly include acetaminophen suppositories, compound pediatric antipyretic suppositories, etc.; intramuscular antipyretic drugs mainly include compound amino acid suppositories. Lin injection, Bupleurum injection, etc.

However, it should be noted that in clinical practice, only when the body temperature exceeds 38.5°C can antipyretic drugs be used for relief treatment under the guidance of a doctor. If the fever does not reach above 38.5°C, antipyretic patches can generally be used. Physical cooling methods such as patching and warm water bathing are used for cooling treatment. If the patient's temperature exceeds 39.5°C, he or she needs to go to the hospital for treatment as soon as possible to avoid serious consequences such as febrile convulsions and nerve damage.
