Treatment of Sore Throat
For acute sore throat, start with systemic analgesics—specifically ibuprofen as first-line (if no contraindications) or paracetamol as an alternative—and reserve antibiotics only for patients with high probability of Group A Streptococcal infection based on clinical scoring. 1, 2
Symptomatic Treatment (First-Line for All Patients)
Systemic analgesics are the cornerstone of sore throat management, as most cases are viral and self-limiting with a mean duration of 7 days. 3
- Ibuprofen is the preferred first-line systemic analgesic, showing slightly better efficacy than paracetamol for pain relief, particularly after 2 hours of administration. 1, 2
- Paracetamol is an effective alternative when ibuprofen is contraindicated, with both medications considered safe for short-term use according to directions. 1, 2
- Both medications have strong evidence supporting their use and low risk of adverse effects. 1, 2
Topical Adjunctive Options
- Local anesthetic sprays or lozenges can be considered as adjunctive therapy for additional symptom relief. 1
- Lidocaine (8mg), benzocaine (8mg), and ambroxol (20mg) have confirmed efficiency in clinical trials, with ambroxol having the best documented benefit-risk profile. 4
- Flurbiprofen 8.75 mg spray provides rapid relief (within 5 minutes) and long-lasting symptom reduction for up to 6 hours. 5
What NOT to Use
- Do not recommend local antibiotics or antiseptics due to the mainly viral origin of sore throats and lack of efficacy data. 1, 4
- Zinc gluconate is not recommended due to conflicting efficacy results and increased adverse effects. 1
- Herbal remedies and alternative treatments lack reliable efficacy data and should not be recommended. 1, 2
Antibiotic Decision-Making Algorithm
Antibiotics should only be considered after risk stratification using clinical scoring systems. 3, 6
Step 1: Exclude Red Flags
- Evaluate for severe systemic infection, immunosuppression, difficulty swallowing, drooling, neck tenderness/swelling, or signs of peritonsillar abscess, parapharyngeal abscess, epiglottitis, or Lemierre syndrome. 7, 3
Step 2: Apply Clinical Scoring (Centor, McIsaac, or FeverPAIN)
- Low risk (< 3 points): No antibiotics indicated 3
- Moderate risk (3 points): Consider delayed prescription 3
- High risk (> 3 points): Antibiotics can be taken immediately 3
Step 3: Consider Testing
- Rapid antigen detection testing and/or throat culture for Group A Streptococcus should be performed when the result will influence therapeutic decision-making. 7, 6
- Testing is most useful in patients with clinical signs suggestive of bacterial pharyngitis (sudden onset, fever, tonsillar exudates, tender anterior cervical lymphadenopathy, absence of cough). 7
Antibiotic Selection When Indicated
When antibiotics are warranted, penicillin remains first-line therapy. 7, 3
First-Line Antibiotic
- Penicillin V for 10 days is the recommended first-line treatment for confirmed Group A Streptococcal tonsillitis. 7
- Amoxicillin is an acceptable alternative for upper respiratory tract infections due to susceptible Streptococcus species. 8
Penicillin-Allergic Patients
- Non-anaphylactic allergy: First-generation cephalosporins 7
- Anaphylactic allergy: Clindamycin, azithromycin, or clarithromycin 7, 3
Treatment Failures
- Amoxicillin-clavulanate, clindamycin, or second/third-generation cephalosporins 7
Duration
- Antibiotics should be taken for 5-7 days minimum, with at least 10 days for Streptococcus pyogenes to prevent acute rheumatic fever. 7, 8, 3
- Short courses are less effective for Group A Streptococcus eradication and should be avoided. 7
Critical Pitfalls to Avoid
- Do not initiate antibiotics without confirming Group A Streptococcus infection through clinical scoring and/or testing, as this leads to unnecessary antibiotic use. 7
- Do not use broad-spectrum antibiotics when narrow-spectrum penicillins are effective for confirmed Group A Streptococcus. 7
- Do not routinely use corticosteroids in self-care settings; they may only be considered in conjunction with antibiotics for severe presentations under medical supervision. 1, 2
- Do not perform follow-up throat cultures for asymptomatic patients who have completed appropriate antibiotic therapy. 7
- Even when antibiotics are indicated, recognize that they only modestly shorten symptom duration (at best). 3, 6
