How Tetracycline Works

Tetracycline prevents bacteria from producing proteins required for growth. Without these proteins, bacteria cannot multiply effectively.

This allows

• The infection to gradually resolve
• Symptoms such as swelling and pain to improve
• The immune system to clear bacteria

The medication treats bacterial infections but does not cure viral illnesses and does not prevent future infections unless clinically indicated.
