A 7-month-old baby has a high fever when he has a fever of 39 degrees. This is the time when the child needs to be treated immediately to reduce the fever, otherwise the child is prone to high fever convulsions, which can cause irreversible damage to the child’s brain cells. You can take oral ibuprofen suspension or acetaminophen granules, depending on the child’s weight, and follow the dosage instructions. It is best to combine this with physical cooling by wiping the child’s armpits, groin, neck and other areas rich in large blood vessels with warm water to help reduce the fever. Adding a Chinese medicine to reduce fever can prevent febrile convulsions, such as antelope horn granules. Also pay attention to indoor ventilation and change the child’s sweaty and wet clothes and bedding in time to prevent the occurrence of secondary chills. You can use antipyretic patches. Although the area of antipyretic patches is small and the effect of reducing fever is limited, it may feel comfortable for children with high fever.
