Under normal circumstances, if the body temperature is lower than 38.5℃, and the patient is in relatively good spirits and daily life is not too affected, you can choose physical cooling first without rushing to take antipyretic drugs. If the patient’s body temperature exceeds 38.5℃, accompanied by poor mental state, decreased appetite, and painful face, some oral antipyretic drugs, such as acetaminophen, or ibuprofen, can be used. When the body temperature exceeds 39℃, especially in some pediatric patients, antipyretic drugs should be used promptly, and intravenous antipyretic drugs can be chosen if necessary to avoid high fever convulsions. When using antipyretic drugs, it is recommended not to use the same one repeatedly, for example, if the patient still has a high fever after 4 hours of acetaminophen application, you can choose ibuprofen. For some infant patients or patients with underlying diseases who are intolerant to oral medications, anal suppositories can be chosen to reduce fever. If the patient develops nausea and vomiting after taking oral antipyretic medication, the antipyretic medication needs to be repeatedly administered. If the patient’s temperature is still not under control after the above treatment, he/she should go to the hospital promptly. In addition, patients should drink plenty of fluids while applying antipyretic drugs. The diet should be based on easily digestible food, with more fresh fruits and vegetables.
