In case of fever and tonsillitis, the first and foremost thing to do is to check the blood count. If there is an increase in the percentage of white blood cells or neutrophils or an increase in the value of the blood test, it indicates a bacterial infection and requires antibiotics to reduce inflammation. Adults can use cefradin, amoxicillin or amoxicillin clavulanate potassium, or if there is an allergy to the above drugs, you can also use roxithromycin to reduce inflammation. In case of children, you can use pediatric cefixime granules, or pediatric cefadroxil granules for anti-inflammatory treatment. If an allergy exists, azithromycin can also be taken to reduce inflammation. If there is no white blood cell or neutrophilia, it is often a viral infection that causes fever and tonsillitis. It is more effective to use anti-inflammatory drugs of the Chinese class, and you can take Pudilan Anti-inflammatory Oral Liquid, which is particularly effective for the treatment of tonsillitis. If the body temperature is above 38.5 degrees, you need to use antipyretic drugs at the same time, you can take ibuprofen suspension orally.
