What precautions should be taken for a sore throat?

Precautions for Sore Throat

For most cases of sore throat, symptomatic treatment with analgesics is recommended rather than antibiotics, as most sore throats are viral in origin and antibiotics provide only modest benefits even in bacterial cases. 1

Diagnostic Approach

• Use the Centor clinical scoring system to identify patients with higher likelihood of group A streptococcal infection (presence of fever, tonsillar exudates, tender anterior cervical lymphadenopathy, and absence of cough) 1
• Consider rapid antigen testing (RAT) in patients with 3-4 Centor criteria who have a higher likelihood of streptococcal infection 1
• Throat culture is not necessary after a negative RAT for diagnosing group A streptococci 1

Treatment Recommendations

Symptomatic Treatment (First-Line)

• Offer analgesic therapy to all patients with sore throat for pain relief 1:
  • Ibuprofen or paracetamol (acetaminophen) are recommended first-line options 1, 2
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen may have the best benefit-risk profile 2
  • Throat lozenges containing local anesthetics (lidocaine, benzocaine, or ambroxol) can provide topical pain relief 2
  • Salt water gargles and other topical remedies are commonly used in clinical practice, though limited data supports their efficacy 1

Antibiotic Treatment (When Indicated)

• Antibiotics should NOT be used in patients with less severe presentation (0-2 Centor criteria) 1
• For patients with 3-4 Centor criteria, consider antibiotics after discussing with patients that benefits are modest (shortening symptoms by only 1-2 days) 1
• If antibiotics are indicated:
  • Penicillin V is the first choice, given twice or three times daily for 10 days 1
  • For penicillin-allergic patients, clarithromycin is an alternative 3
  • Delayed antibiotic prescribing (waiting 48+ hours) is a valid option 1

Important Considerations

• Reassure patients that the typical course of sore throat is less than one week 1
• Most cases (>65%) of sore throat are viral in origin and do not require antibiotics 1, 3
• Antibiotics should be reserved for confirmed streptococcal pharyngitis to prevent unnecessary side effects and antibiotic resistance 1
• The prevention of suppurative complications alone is not a specific indication for antibiotic therapy in most cases of sore throat 1

Special Situations and Red Flags

• Be vigilant for Lemierre syndrome in adolescents and young adults with severe pharyngitis, which requires urgent diagnosis and treatment 1
• Watch for signs of peritonsillar abscess (quinsy), which may require more aggressive intervention 1
• Consider the patient's risk for rheumatic fever, which is rare in developed countries but may be more common in certain populations 1, 4
• Immunocompromised patients or those with severe systemic symptoms may require different management approaches 3

Herbal Treatments and Alternative Therapies

• There is inconsistent evidence supporting herbal treatments and acupuncture for sore throat 1
• Zinc gluconate is not recommended for use in sore throat 1
