Tetracycline — Uses, Dosage, Side Effects & Safety

Drug class: Antibiotic (Tetracycline class)

Overview

Tetracycline is an antibiotic used to treat a wide variety of bacterial infections, including respiratory tract infections, acne, urinary tract infections, and certain sexually transmitted infections. It is also sometimes used to treat infections caused by uncommon bacteria, such as rickettsiae and chlamydia. Tetracycline works by stopping the growth of bacteria. It does this by interfering with the bacteria's ability to produce proteins that are essential for their survival. This helps your body's immune system to eliminate the infection. Key points: Tetracycline will not work for viral infections (like colds or flu). It is important to take the full course as prescribed, even if you feel better, to prevent the infection from returning and to reduce the risk of antibiotic resistance.
