Tablet for pharyngitis
Reading File
For pharyngitis, the main tablet treatments are antibiotics (for bacterial/streptococcal pharyngitis) and analgesics/anti-inflammatories. Penicillin V or amoxicillin is the first-line antibiotic choice. NSAIDs like ibuprofen help with pain and fever.

Here is a comprehensive summary of tablet (oral) treatment options for pharyngitis, drawn primarily from Harrison's 22E and Goldman-Cecil Medicine:
Tablets for Pharyngitis
When to Treat with Antibiotics
Antibiotics are indicated only for Group A Streptococcus (GAS) pharyngitis - most pharyngitis is viral and does not need antibiotics. Use the Centor Criteria to guide decision-making:
| Centor Score | GAS Probability | Action |
|---|---|---|
| 0-1 | 2-3% | No test, no antibiotic |
| 2-3 | 8-19% | Rapid antigen test; treat if positive |
| 4 | ~41% | Empirical antibiotic or rapid test |
(Centor criteria: fever, no cough, tender anterior cervical lymphadenopathy, tonsillar exudate/swelling - 1 point each)
Antibiotic of Choice
| Drug | Dose | Duration |
|---|---|---|
| Penicillin V (VK) | 500 mg PO 4x/day OR 1000 mg PO 2x/day | 10 days |
- First-line for all patients without penicillin allergy
- No GAS resistance to penicillin has ever been documented
- Narrow spectrum, low cost, well tolerated
Alternatives for Non-Penicillin-Allergic Patients
| Drug | Dose | Duration |
|---|---|---|
| Amoxicillin | 500 mg PO 2x/day OR 1000 mg PO once daily | 10 days |
| Cephalexin | 500 mg PO 2x/day | 10 days |
| Cefadroxil | 1 g PO once daily | 10 days |
Alternatives for Penicillin-Allergic Patients
Mild allergy (non-anaphylactic): Cephalexin or Cefadroxil (as above)
Severe allergy (anaphylaxis):
| Drug | Dose | Duration |
|---|---|---|
| Azithromycin | 500 mg day 1, then 250 mg/day | 5 days |
| Clarithromycin | Standard dose | 10 days |
| Erythromycin | Standard dose | 10 days |
| Clindamycin | 300 mg PO 3x/day | 10 days |
For recurrent infections: Clindamycin 300 mg 3x/day x 10 days, or amoxicillin-clavulanate 875 mg 2x/day x 10 days.
Symptomatic Relief (All Pharyngitis, Including Viral)
All patients - regardless of cause - benefit from:
- Analgesics/antipyretics: Ibuprofen (NSAID) or paracetamol (acetaminophen) tablets for pain and fever
- Saline gargles, soft foods, honey in tea
Note: Corticosteroids (e.g., dexamethasone) are not recommended - short-term benefit in pain is offset by risks of sepsis, GI bleeding, and VTE within 30 days.
Key Points
- Course duration matters: 7-10 days is required - shorter courses are less effective for GAS pharyngitis
- Treatment within 10 days of onset prevents acute rheumatic fever
- Antibiotic treatment does NOT prevent post-streptococcal glomerulonephritis
- Viral pharyngitis (EBV/mono, adenovirus, etc.) - treat symptomatically only
