If a child has a fever at night and there is no medicine at home, it should be treated according to the temperature as follows: 1. Physical cooling: Drinking warm water or repeatedly wiping with warm water to alternate physical cooling can make the temperature drop or recede to normal as much as possible. 2. Because there is no medicine at home, it is necessary to take the child to the hospital for a detailed examination to clarify the cause of the disease and to treat the cause under the guidance of the doctor. If the child’s temperature does not go back to normal or continues to rise, he or she should be taken to the hospital for a detailed examination to determine the cause of the problem and to treat the cause under the guidance of a doctor. 3. The most common choice for children is acetaminophen or ibuprofen.
