I now have comprehensive information from Harrison's Principles of Internal Medicine (2025 edition). Here is a thorough answer:
Sore Throat (Pharyngitis) - Medications & Their Uses
A sore throat lasting 2 days is very common and most cases are caused by viral infections (rhinovirus, coronavirus, adenovirus). Only about 10-15% of adult cases are bacterial (Group A Streptococcus - "strep throat"). Treatment differs based on the likely cause.
Step 1 - Assess If You Have Strep (Bacterial) Features
The Centor Criteria help identify strep throat. Score 1 point for each:
-
Fever history
-
No cough
-
Tender neck glands (anterior cervical lymphadenopathy)
-
Swollen or white-coated tonsils (tonsillar swelling/exudate)
-
Score 0-1: Very unlikely strep - no antibiotic needed
-
Score 2-3: Consider a rapid strep test
-
Score 4: Likely strep - consider testing or antibiotics
Medications for Sore Throat
1. Pain Relievers (for ALL sore throats - viral or bacterial)
| Medication | Dose (Adult) | Use |
|---|
| Paracetamol (Acetaminophen) | 500-1000 mg every 6-8 hrs | Reduces throat pain and fever; first-line; safe for most |
| Ibuprofen (NSAID) | 400 mg every 6-8 hrs with food | Reduces pain, inflammation, and fever; slightly better than paracetamol for throat pain |
"All patients with pharyngitis - nonstreptococcal and streptococcal - should receive analgesics (acetaminophen or NSAIDs)." - Harrison's Principles of Internal Medicine, 22nd Edition (2025)
Take ibuprofen with food to protect your stomach. Avoid it if you have kidney issues or a stomach ulcer.
2. Throat Lozenges & Sprays (Local Relief)
| Product Type | Active Ingredient | Use |
|---|
| Numbing lozenges/sprays | Benzocaine, lidocaine | Temporarily numbs throat pain |
| Antiseptic lozenges | Cetylpyridinium, hexylresorcinol | Mild antimicrobial, soothe irritation |
| Demulcent lozenges | Honey, glycerin, pectin | Coat and soothe the throat lining |
Note: Guidelines advise against local antibiotic-containing throat preparations as they are largely ineffective for viral sore throats.
3. Antibiotics (ONLY for confirmed/likely bacterial strep throat)
Antibiotics are not needed unless you test positive for strep or score 4 on the Centor criteria. Overuse leads to antibiotic resistance.
| Antibiotic | Dose | Duration | Notes |
|---|
| Penicillin V (first choice) | 500 mg 4x/day OR 1000 mg 2x/day | 10 days | Narrow-spectrum, safe, no resistance reported |
| Amoxicillin (good alternative) | 500 mg 2x/day OR 1000 mg once daily | 10 days | Preferred in children (available as liquid) |
| Cephalexin (if mild penicillin allergy) | 500 mg 2x/day | 10 days | Good alternative |
| Cefadroxil (if mild penicillin allergy) | 1 g once daily | 10 days | Convenient once-daily dosing |
| Erythromycin / Clarithromycin (severe penicillin allergy) | As prescribed | 10 days | Macrolide class |
| Clindamycin (severe penicillin allergy) | As prescribed | 10 days | Use if macrolide resistance suspected |
Strep throat requires a full 7-10 day antibiotic course - shorter courses are less effective and risk rheumatic fever. - Harrison's, 2025
4. What Is NOT Recommended
- Glucocorticoids (steroids like dexamethasone) - Not routinely recommended. Short courses are linked to increased risk of sepsis, GI bleeding, and fractures within 30 days.
- Routine antibiotics without strep testing - Not recommended for adults with low Centor scores.
Supportive Remedies (Very Helpful)
- Saline gargles - Warm salt water gargle 3-4x daily soothes pain
- Warm honey-lemon tea - Demulcent, soothing, and mild antimicrobial
- Cold beverages / ice chips - Numbing effect
- Stay well hydrated - Prevents dryness and aids recovery
- Humidifier in room - Reduces throat dryness overnight
- Soft foods - Easier to swallow
When to See a Doctor Urgently
Seek medical attention if you develop:
- High fever with shaking chills (rigors)
- Neck swelling beyond normal lymph nodes
- Difficulty swallowing or drooling
- Difficulty breathing or opening mouth
- Symptoms not improving after 5 days
These could signal a peritonsillar abscess, epiglottitis, or deep neck infection - conditions requiring urgent treatment.
Summary for your 2-day sore throat: Start with ibuprofen or paracetamol for pain relief and saline gargles + warm fluids. If you have fever, swollen tonsils with white patches, tender neck glands, and no cough - see a doctor for a strep test. Antibiotics are only warranted if strep is confirmed.
