Minocycline — Uses, Dosage, Side Effects & Safety

Drug class: Infection & Antibiotics

Overview

Minocycline is an antibiotic used to treat a wide range of bacterial infections, including acne, respiratory tract infections, urinary tract infections, and certain sexually transmitted infections. It is also sometimes prescribed for other conditions as determined by your healthcare provider. Minocycline works by stopping the growth of bacteria. It belongs to the tetracycline class of antibiotics, which block bacteria from making the proteins they need to survive. This helps your body’s immune system clear the infection.

Complete the full course, even if you feel better, to prevent antibiotic resistance.
