After too much fever-reducing medication has been given to an infant or young child, electrolytes can be replaced with light saline, vomiting and gastric lavage can be performed, and liver and kidney function tests can be performed. Fever reducers for infants and young children are usually ibuprofen or acetaminophen. If the child may sweat a lot after taking too much antipyretic in infants and young children, the child can be allowed to drink some light saline to prevent electrolyte disorders and dehydration. Parents are advised to take their children to the hospital for emetic and gastric lavage. Because ibuprofen or acetaminophen requires detoxification by the liver and metabolism by the kidneys, large amounts ingested may affect liver and kidney function, so parents should also take their children to the hospital to have their liver and kidney function checked. Ibuprofen and acetaminophen have the potential to cause adverse reactions such as stomach bleeding, and should be used under a doctor’s supervision. If an infant or toddler takes too much fever-reducing medication, it is recommended that the child be given small amounts of saline water to drink several times and go to the hospital in a timely manner to have the vomiting or gastric lavage operation performed by a medical professional.
