Purulent tonsillitis is an acute bacterial infection in the throat characterized by purulent lesions. Clinical examination reveals congested and enlarged tonsils with greyish-white or white pseudomembranous inflammatory secretions covering the surface of the tonsils or the area of the throat. Active anti-infection treatment is necessary for purulent tonsillitis. The criteria for discontinuing medication include the disappearance of clinical symptoms, such as the absence of sore throat; reduction of tonsil congestion, and reduction or disappearance of the pseudomembrane on the tonsil surface. Additionally, other factors should be considered, such as the results of a complete blood count, with white blood cell levels returning to normal reference ranges. Further considerations include complications such as concurrent arthritis or glomerulonephritis. If clinical examinations or signs suggest these are resolved, cessation of medication for purulent tonsillitis may be considered, typically continuing the process for about one to two weeks.
