Giving antipyretics to children with fever up to 37.5℃ may cause bodily injuries such as aggravation of the burden on the liver and kidneys and hypothermia. 1. Exacerbate the burden on the liver and kidneys: because the child’s liver and kidney function itself is not yet fully developed, if you take antipyretics when the body temperature is low, it may increase the burden on the child’s liver and kidneys, and cause abnormalities in the child’s liver and kidney function. 2. Low body temperature: children’s fever of 37.5 ℃ is generally considered to be low-grade fever, if you take fever-reducing drugs too early, may make the body sweat a lot, so that the body temperature drops rapidly, resulting in children’s hypothermia. Therefore, it is recommended that when the child is at 37.5 ℃, the physical cooling method of wiping the body with warm water can be chosen. If the physical cooling method is ineffective and the child’s temperature rises above 38.5 ℃, fever-reducing medicines such as ibuprofen can be used under the guidance of a doctor.
