A fever with an increased percentage of neutrophils indicates a fever caused by a bacterial infection and requires oral antibiotics for treatment. If the cephalosporin is not allergic, adults can choose cefadroxil or cefradine. If it is a child, you can choose pediatric cefixime granules or pediatric cefadroxil granules. If the effect of oral medication is not enough, intravenous drip antibiotics are needed for treatment. If cephalosporin is not allergic, imported ceftriaxone can be used for treatment, and the effect is still good. In addition, you can also use Astragalus injection, which can avoid myocarditis and enhance the child’s resistance, which is particularly good for the recovery of the disease.
