When a 12-year-old child has a fever, the specific way to reduce the fever needs to be determined by the child’s fever temperature. If the body temperature is below 38.5℃, only give the child some Chinese medicine to reduce fever. The effect of Chinese fever medicine is slow and less drastic, and it is suitable for low fever, such as pediatric antelope horn granules or cold and fever granules. If the body temperature is above 38.5℃, you need to take antipyretic and analgesic drugs for treatment. At this time, you can give your child pediatric acetaminophen suspension, the specific dosage needs to be based on the child’s weight and age and instructions. It is best to give the child a combination of physical cooling, physical cooling can reduce the use of antipyretic drugs, but also prolong the effect of antipyretic drugs, for example, you can use warm water to wipe the child’s skin all over the body.
