When a child has a fever caused by a viral infection, the choice of antipyretic medication should be based on the temperature. If the body temperature is between 37-38.5℃, the fever caused by viral infection needs to be combined with antiviral drugs for comprehensive treatment before the body temperature can return to normal and the condition can be relieved. If the temperature is above 38.5℃, the child needs to be given fever-reducing medication in a timely manner. The common medications used are ibuprofen suspension or acetaminophen suspension, and compound zinc pellets to reduce fever. When your child has a high fever, you must always observe the change in body temperature and give your child more water to bring the body temperature back to normal as soon as possible to avoid febrile convulsions. Keep the air convection in the room and reduce the intake of high-calorie food.
