Doxycycline

Doxycycline is a common antibiotic often used for the treatment of various infections, such as bacterial infections, anthrax, malaria, and acne. The medication is part of a class of drugs called tetracyclines, and works by decreasing bacteria's ability to make protein (which it needs to live). Doxycycline is available in several forms, and is usually taken once or twice a day.

How Does It Work?

Doxycycline is part of a class of drugs called tetracyclines. It decreases bacteria's ability to make protein, which bacteria need to live. This activity does not directly kill the bacteria, but it does inhibit their growth and multiplication, which gives the immune system a chance to fight the infection. For treating gum disease, doxycycline actually works to inhibit an enzyme in the saliva known as collagenase.
