If your child’s fever does not go down even after a fever-reducing injection, the following measures can be taken: First, give another fever-reducing injection. If the fever does not go down after four hours, the child may be given a refill. Second, give the child plenty of warm water or intravenous fluids. The reason why some children do not reduce fever after applying the antipyretic injection is due to the low amount of water in the body, if the water in the body is low, it is difficult to sweat enough and the effect of reducing fever will not occur. When children are hydrated in time, most of the antipyretic injections will be effective, and the child’s temperature will slowly drop. Finally, children can be given oral antipyretic drugs, such as acetaminophen or ibuprofen.
