A child who keeps having a fever of 38°C that does not go away often indicates the presence of bacterial, viral or other infections in the body that can cause respiratory or digestive system infections. If there is a respiratory infection, it is often accompanied by nasal congestion, runny nose, sore throat or coughing and phlegm, which can be treated with Pudilan Anti-inflammatory Oral Liquid, Blue Scutellaria Oral Liquid or Four Seasons Anti-Viral Combination. If accompanied by elevated white blood cells, antibiotic treatment is also needed, such as cefixime granules for pediatric patients or cefadroxil for pediatric patients, which are effective. If there are digestive symptoms, often nausea, vomiting or abdominal pain and diarrhea, the child usually needs to be treated with anti-diarrheal Simethicone. In case of bacterial infection, it is also necessary to also take pediatric cefaclor granules or pediatric cefixime granules to reduce inflammation.
