You can take antipyretics for fevers below 38°C, but they are generally not recommended. Because fever is a normal protective reaction of the body, as long as the fever is not high, i.e., above 38.2°C, there is no need to take antipyretics, and the symptoms of fever can be eliminated by treating the cause. In addition, blindly reducing fever will also cover up the condition and is not conducive to the diagnosis of the disease. When you have a low fever, you can use physical cooling methods, such as warm water rubs or alcohol baths. However, it should be noted that patients taking cephalosporins, nitroimidazoles and nitrofurans should not use alcohol baths to prevent disulfiram-like reactions. In addition, it should be noted that a high fever must be reduced before seeing a doctor, because many enzymes in the body will be denatured when the fever is high, resulting in the loss of their functions and disruption of various biochemical reactions of the body.
