Oxytetracycline — Uses, Dosage, Side Effects & Safety

Drug class: Antibiotic (Tetracycline class)

Overview

Oxytetracycline is an antibiotic used to treat a wide range of bacterial infections, including respiratory tract infections, skin infections (such as acne), urinary tract infections, and certain sexually transmitted infections. It is also used in veterinary medicine. This medication 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. Oxytetracycline is only effective against bacterial infections and will not work for viral illnesses like the common cold or flu. Key points: Take oxytetracycline exactly as prescribed, usually on an empty stomach. Complete the full course, even if you feel better, to prevent antibiotic resistance. Avoid taking it with dairy products or antacids, as these can reduce its effectiveness.
