Recurrent fever can also occur in children with food retention, as long as the state of food retention is not improved. At this time, the first thing to do is to improve the child’s condition of food accumulation. If the child vomits, it is necessary to give the child more than 4 hours of water and food fasting. If the child’s vomiting is relieved, you can gradually give the child small amounts of water, some medicines or thin rice soup. There are many medicines to improve the accumulation of food, such as Da Shan Hua Granules, Noon Tea Granules, Cigarette Cough Granules or Pediatric Seven Star Tea Granules, all of which are more effective and have a better taste and are not particularly hard to drink. In addition, medicines for fever need to be used. If the temperature of the fever is relatively low, below 38.5℃, physical cooling methods can be used, such as rubbing the child’s whole body skin with a warm towel. If the temperature is higher, you need to give your child ibuprofen suspension for fever reduction.
