The fastest way to reduce fever is to use antipyretic drugs. Antipyretic drugs can be divided into three types: oral, suppository and intramuscular. Oral antipyretic drugs include ibuprofen suspension, acetaminophen oral solution, etc.; suppository antipyretic drugs include acetaminophen suppositories, compound pediatric antipyretic suppositories, etc.; intramuscular injection antipyretic drugs include compound aminopyrine injection, Chaihu injection, etc. However, it should be noted that clinically, only if the body temperature exceeds 38.5℃, can you choose antipyretic drugs for relief treatment under the guidance of a doctor. If the fever does not reach 38.5℃ or above, you can generally use physical cooling methods such as applying antipyretic patches and warm water baths for cooling treatment. If the patient’s body temperature exceeds 39.5℃, it is necessary to go to the hospital for medical treatment as soon as possible to avoid serious consequences such as high fever convulsions and nerve damage.
