How Tetracycline Works

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

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.
