Approach to Sore Throat in Adults

Initial Assessment and Management

The American College of Physicians recommends immediately evaluating for severe complications if the patient presents with unusually severe symptoms, lack of response to initial therapy, or any red flag features, such as peritonsillar abscess, retropharyngeal abscess, epiglottitis, or Lemierre syndrome, which can be life-threatening 1
The Infectious Diseases Society of America suggests looking for unilateral tonsillar swelling, uvular deviation, trismus, "hot potato voice," and severe difficulty swallowing to diagnose peritonsillar abscess 1
The American Academy of Otolaryngology recommends assessing for neck stiffness, neck tenderness or swelling, drooling, and difficulty swallowing to diagnose retropharyngeal abscess 1
The Centers for Disease Control and Prevention advises evaluating for drooling, stridor, sitting forward position, and respiratory distress to diagnose epiglottitis, which is an airway emergency 1
The European Society of Clinical Microbiology and Infectious Diseases suggests considering Lemierre syndrome in adolescents and young adults with severe pharyngitis and high fever, as this can progress to life-threatening septic thrombophlebitis 1, 2

The American Academy of Family Physicians recommends either ibuprofen or paracetamol as first-line treatment for relief of acute sore throat symptoms, with ibuprofen and diclofenac providing slightly more effective pain relief than paracetamol 3, 4
The European Respiratory Society suggests using the Centor criteria or similar validated scores like McIsaac or FeverPAIN to stratify the probability of bacterial pharyngitis before prescribing antibiotics, with a low risk (<3 points) indicating no antibiotics are needed, a moderate risk (3 points) indicating a delayed prescription strategy, and a high risk (>3 points) indicating immediate antibiotic therapy 5
The Infectious Diseases Society of America recommends penicillin V as the first-line choice for antibiotic therapy, with a dosage of 250-500 mg twice or three times daily for 10 days, and alternative options including amoxicillin, first-generation cephalosporin, clindamycin, azithromycin, or clarithromycin 2, 5

The American College of Physicians suggests that a sore throat lasting beyond 2 weeks is atypical and warrants evaluation for non-infectious causes and serious pathology, with most viral and bacterial pharyngitis resolving within 7 days 6, 2
The European Society of Clinical Microbiology and Infectious Diseases recommends laryngoscopy to directly visualize the larynx and pharynx, typically using transnasal flexible fiberoptic scope, and considering non-infectious etiologies such as gastroesophageal reflux disease, neoplastic processes, or chronic carrier state 6, 2

The Centers for Disease Control and Prevention notes that antibiotics reduce the incidence of acute otitis media, peritonsillar abscess, and acute rheumatic fever, but the decision to prescribe antibiotics must weigh modest benefits against antibiotic resistance, side effects, and costs 5

The American Academy of Family Physicians advises against prescribing antibiotics empirically without clinical assessment, as over 60% of adults with sore throat receive unnecessary antibiotics 6
The European Respiratory Society recommends against using zinc gluconate, herbal treatments, or acupuncture due to conflicting evidence, higher adverse effects, or insufficient reliable evidence for efficacy 3
