Pediatric ibuprofen suspension is a commonly used antipyretic medication for pediatric patients, and in principle, it is taken orally according to the instructions, not more than 4 times within 24 hours. For how often it should be taken, it should be taken orally according to the temperature of the child, and generally ibuprofen suspension can be taken orally when the body temperature is ≥38.5℃. However, because the drug has some damage to the liver and kidney function of pediatric patients, it should be taken orally according to the instructions and not more than 4 times. If the child’s fever recurs within 24 hours, in addition to oral antipyretic drugs, parents should actively take physical cooling to assist in fever reduction, as little as possible with antipyretic drugs, to avoid damage to the liver and kidney function of the child. Physical cooling can choose to drink more water or the application of antipyretic patches, or with warm water repeatedly and constantly on the child to wipe, but also can take a hot bath, can play a good role in reducing fever.
