The preferred antibiotic for patients treating tonsillitis is penicillin, and amoxicillin clavulanic acid potassium, cefprozil, metronidazole, etc. are also available. If oral medication cannot be controlled, cefotaxime sodium and metronidazole can be used intravenously. Tonsillitis is a streptococcal infection that can cause pain in the pharynx, fever, and enlarged lymph nodes in the neck. On examination, the mucous membrane of the pharynx is congested and swollen, the tonsils may be enlarged, and there may be purulent secretions attached to the surface of the tonsils, which are easily swabbed away. Treatment requires antibiotic therapy, and the course of treatment is usually one week. For recurrent tonsillitis, tonsillectomy should be considered half a month after inflammation control, and exercise should be strengthened to enhance body resistance and reduce the occurrence of upper respiratory tract infection.
