Levofloxacin is a broad-spectrum antibiotic used to treat a variety of bacterial infections. It is commonly prescribed for respiratory infections such as pneumonia, acute bronchitis, and sinusitis, as well as urinary tract infections (UTIs), skin infections, and even certain types of gastroenteritis. It’s effective against a range of bacteria, including both gram-positive and gram-negative bacteria. Levofloxacin works by disrupting the bacteria’s DNA replication process, preventing it from multiplying and spreading. This antibiotic is typically used when other treatments haven’t worked or when the infection is caused by bacteria resistant to other antibiotics.
