There are two main types of fever-reducing drugs for babies: the first is ibuprofen, which is mainly used for babies older than 6 months, with a dose of 5-10 mg/kg each time, and no more than 4 doses per 24 hours, with an interval of more than 4 hours between doses. The second drug is acetaminophen, which is suitable for babies older than 3 months of age. The dose is 10-15 mg/kg per dose and should not be taken more than 5 times per 24 hours, with an interval of more than 4 hours between doses. When taking antipyretic drugs, the body temperature is above 38.5℃, and also take into account the child’s spirit. If the child’s spirit is not good because of fever, it is not necessary to wait until 38.5℃ to take antipyretic drugs. If the child’s spirit is good, you can also wait until 38.5℃ or more.
