Treatment for Sore Throat
For acute sore throat, either ibuprofen or paracetamol (acetaminophen) are recommended as first-line treatment for symptom relief, while antibiotics should only be considered for patients with high likelihood of streptococcal infection (3-4 Centor criteria). 1
Diagnostic Approach
Before determining treatment, assess the likelihood of bacterial infection using clinical scoring systems:
- The Centor clinical scoring system helps identify patients with higher likelihood of group A streptococcal infection 1
- Criteria include: fever, absence of cough, tonsillar exudates, and tender anterior cervical lymphadenopathy 2
- In patients with high likelihood of streptococcal infections (3-4 Centor criteria), consider using rapid antigen tests (RATs) 1
- For patients with lower likelihood (0-2 Centor criteria), RATs are not routinely needed 1
First-Line Treatment: Symptomatic Relief
Analgesics
- Either ibuprofen or paracetamol (acetaminophen) are recommended for relief of acute sore throat symptoms 1
- Evidence suggests ibuprofen may have the best benefit-risk profile among available analgesics 3
- NSAIDs (like ibuprofen and naproxen) are more effective than acetaminophen for treating fever and pain associated with sore throat 4, 2
Local Treatments
- Medicated throat lozenges used every two hours can provide effective symptom relief 2
- Local anesthetics with confirmed efficacy include lidocaine (8mg), benzocaine (8mg), and ambroxol (20mg) 3
- Ambroxol lozenges (20mg) have shown efficacy and safety in randomized controlled trials for acute uncomplicated sore throat 5
Antibiotic Treatment
When to Use Antibiotics
- Antibiotics should NOT be used in patients with less severe presentation (0-2 Centor criteria) 1
- For patients with 3-4 Centor criteria, modest benefits of antibiotics must be weighed against side effects, impact on microbiota, increased resistance, and costs 1
- The prevention of suppurative complications is not a specific indication for antibiotic therapy 1
- Sore throat should not be treated with antibiotics to prevent rheumatic fever in low-risk patients 1
Choice of Antibiotic
- If antibiotics are indicated, penicillin V twice or three times daily for 10 days is the recommended first choice 1
- For patients allergic to penicillin, alternatives include first-generation cephalosporins, clindamycin, or macrolide antibiotics 2
- For poor patient compliance, benzathine penicillin G can be administered parenterally in a single dose 6
- Current evidence does not support shorter treatment durations 1
Other Treatment Options
Corticosteroids
- Corticosteroids are not routinely recommended for treatment of sore throat 1
- They can be considered in adult patients with more severe presentations (3-4 Centor criteria) in conjunction with antibiotic therapy 1
- Corticosteroids provide only a small reduction in symptom duration and should not be used routinely 2
Treatments Not Recommended
- Zinc gluconate is not recommended for use in sore throat due to conflicting results and increased adverse effects 1
- Local antibiotics or antiseptics should not be recommended due to the mainly viral origin of sore throat and lack of efficacy data 3
- There is inconsistent evidence for herbal treatments and acupuncture as treatments for sore throat 1
Special Considerations
- Most cases of acute sore throat are self-limiting with a mean duration of 7 days 4
- For streptococcal pharyngitis, a 10-day course of penicillin or amoxicillin is necessary to prevent complications like rheumatic fever 7, 2
- Delayed antibiotic prescribing (waiting >48 hours) is a valid option for patients with intermediate risk 1
- Patients should be encouraged in self-management of symptoms 4
