The "preferred" antibiotics for a cough, as recommended by guidelines, are tetracycline and amoxicillin. If someone has a hypersensitivity to these, then macrolides are recommended as an "alternative" antibiotic.
Understanding Antibiotics for Coughs
It's important to clarify that antibiotics are only effective against bacterial infections, not viral ones. Many coughs are caused by viruses like the common cold, and these will not respond to antibiotics. However, if a cough is caused by a bacterial infection, then antibiotics may be necessary.
Antibiotic Options
| Antibiotic Class | Specific Antibiotic(s) | Use |
|---|---|---|
| Tetracycline | Tetracycline | Preferred, if no hypersensitivity |
| Penicillins | Amoxicillin | Preferred, if no hypersensitivity |
| Macrolides | Erythromycin, Azithromycin, Clarithromycin | Alternative, in cases of hypersensitivity |
Key Considerations:
- Not all coughs require antibiotics. Viral infections are often the culprit.
- Antibiotic resistance: Overuse of antibiotics can lead to bacteria becoming resistant to them, making future infections harder to treat.
- Consult a doctor: Always consult a healthcare professional for diagnosis and treatment before starting any antibiotic.
Summary
If a cough is due to a bacterial infection, recommended antibiotics include tetracycline and amoxicillin, with macrolides being an alternative if there's a hypersensitivity. However, it is best to consult a doctor before using any antibiotic.
