Treatment of Bacterial Tonsillitis

Diagnosis and Treatment

The American Academy of Otolaryngology-Head and Neck Surgery recommends testing with rapid antigen detection test (RADT) and/or throat culture for Group A Streptococcus (GAS) before initiating antibiotics, and bacterial tonsillitis typically presents with sudden onset of sore throat, fever, tonsillar exudates, tender anterior cervical lymphadenopathy, and absence of cough 2, 3
The Infectious Diseases Society of America recommends penicillin V for 10 days as the first-line treatment for confirmed bacterial tonsillitis, with amoxicillin for 10 days as an acceptable alternative 1, 2, 3
For penicillin-allergic patients, the American Academy of Otolaryngology-Head and Neck Surgery recommends cephalexin, cefadroxil, clindamycin, azithromycin, or clarithromycin as alternative treatments 1, 3

The American Academy of Otolaryngology-Head and Neck Surgery recommends tonsillectomy for recurrent throat infection with at least 7 episodes in the past year, or at least 5 episodes per year for 2 years, or at least 3 episodes per year for 3 years, with each episode documented in the medical record with at least one of the following: temperature >38.3°C, cervical adenopathy, tonsillar exudate, or positive test for GAS 2, 4

The American Academy of Otolaryngology-Head and Neck Surgery recommends ibuprofen, acetaminophen, or both for pain control, and follow-up with patients/caregivers to document presence or absence of bleeding, and monitor for primary and secondary bleeding 4
