First-Line Treatment for Sore Throat
The first-line treatment for acute sore throat is symptomatic management with systemic analgesics, specifically ibuprofen (preferred if no contraindications) or paracetamol (acetaminophen), without routine antibiotic use. 1, 2
Recommended Symptomatic Treatment Approach
Primary Analgesic Options
Ibuprofen is the preferred first-line systemic analgesic for acute sore throat, showing slightly better efficacy than paracetamol for pain relief, particularly after 2 hours of administration 1, 2
Paracetamol (acetaminophen) is an effective alternative when ibuprofen is contraindicated or not tolerated, with strong evidence supporting its use for reducing acute sore throat symptoms 1, 2
Both medications are considered safe when used according to directions for short-term treatment, with low risk of adverse effects 1, 2
Adjunctive Topical Therapy
Local anesthetic sprays or lozenges containing lidocaine (8mg), benzocaine (8mg), or ambroxol (20mg) can be considered as adjunctive therapy for additional symptom relief 1, 3
Among local anesthetics, ambroxol has the best documented benefit-risk profile in acute sore throat therapy 3
Antibiotic Considerations
When Antibiotics Are NOT Indicated
Routine antibiotic treatment is not indicated for acute sore throat, as the majority (>65%) of cases are viral in origin and self-limiting with a mean duration of 7 days 4, 5
Antibiotics should not be used in patients with low-risk presentations (0-2 Centor criteria) as they provide minimal symptomatic benefit and contribute to antibiotic resistance 2, 5
Risk-Stratified Antibiotic Approach (When Considered)
Clinical scoring systems (Centor, McIsaac, or FeverPAIN) should be used to assess the risk of bacterial pharyngitis before considering antibiotics 5
At low risk (<3 points): antibiotics are not indicated 5
At moderate risk (3 points): delayed prescription is an option 5
At high risk (>3 points): antibiotics can be taken immediately, though evidence suggests only modest shortening of symptom duration 5
If antibiotics are prescribed, penicillin V for 10 days is first-line for confirmed Group A Streptococcus pharyngitis, with clarithromycin or first-generation cephalosporins as alternatives for penicillin-allergic patients 6, 5
Important Pitfalls to Avoid
Do not recommend local antibiotics or antiseptics for sore throat treatment due to the mainly viral origin and lack of efficacy data 1, 2, 3
Corticosteroids should not be routinely used in self-care settings, though they may be considered in conjunction with antibiotic therapy for severe presentations under medical supervision 1, 2
Zinc gluconate is not recommended due to conflicting efficacy results and increased adverse effects 1, 2
Alternative treatments such as herbal remedies or acupuncture lack reliable data supporting their efficacy and should not be recommended 1, 2
Avoid prescribing broad-spectrum antibiotics (extended-spectrum macrolides, fluoroquinolones) when narrow-spectrum penicillins are effective for confirmed bacterial infections 7
Special Populations
- In children, both ibuprofen and paracetamol are effective for sore throat symptoms with no significant difference in analgesic efficacy or safety between the two 1, 2
Red Flags Requiring Urgent Evaluation
Severe cases with difficulty swallowing, drooling, neck tenderness, or swelling should be evaluated for serious complications like peritonsillar abscess, parapharyngeal abscess, epiglottitis, or Lemierre syndrome 6
Immunosuppression or signs of severe systemic infection warrant immediate medical evaluation 5
