Acute tonsillitis is an acute, infectious inflammation of the tonsils, primarily caused by bacterial infection. For the treatment of acute tonsillitis, we mainly adopt antibiotic treatment for infection. The general course of treatment lasts 7-10 days, especially for acute suppurative tonsillitis, which may even extend to about 10-14 days. Clinically, we primarily administer cephalosporin antibiotics to control the infection. If the infection is severe, we may even opt for infusion therapy to counter the infection. During the infusion, we can administer some corticosteroids such as dexamethasone to treat concurrently, enhancing the anti-inflammatory effect. Clinically, we should pay attention to drinking plenty of water and eating a light diet, avoiding spicy and irritating foods.
