Tetracycline is a custom pharmacy drug classified in the family of drugs called tetracycline antibiotics.

Tetracycline is widely utilized in modern medicine for a host of conditions such as infections of the intestinal, genital, urinary, eye, and lymphatic systems; respiratory tract infections; pneumonia; infections caused by lice, mites, ticks and infected animals; certain types of plague, and more.
