Tonsillitis caused by a viral infection is treated differently than tonsillitis caused by a bacterial infection. Generally, tonsillitis caused by a bacterial strep infection can be successfully treated with an antibiotic medication. Viral tonsillitis is not treated with antibiotic medications because antibiotics are ineffective at defeating viral infections, but may be treated with other antiviral medications. With chronic and recurrent tonsillitis, a surgical procedure to remove the tonsils may be recommended. 

If a peritonsillar abscess has developed, urgent treatment to prevent airway obstruction may be required.
