When the body temperature reaches 38.5℃, you can take antipyretic medicine at this time, but different decisions need to be made depending on the situation. If the body temperature is at 38.5℃ and the patient has obvious symptoms, such as fear of cold, headache, and the feeling of fever is more obvious, you need to take antipyretic medicine as much as possible. Because the patient’s symptoms are already more pronounced, there is a possibility that the symptoms will persist or even continue to worsen if the patient does not take antipyretic medication. If the patient does not feel anything at this time, although the temperature reaches 38.5 ℃, but there is no headache, chills or general muscle aches, it is possible not to take antipyretics at this time, it is likely that the temperature can be reduced to roughly normal range after a period of time, so this will have to be determined by the situation. In addition, if the child has had febrile convulsions in the past, even if the temperature does not reach 38.5 ℃, you need to take antipyretic drugs, or even apply other methods to control the temperature in the normal range to avoid the symptoms of febrile convulsions.
