What is Levofloxacin?
Levofloxacin, commonly sold under the brand name Levaquin, is a potent antibiotic. It's used to treat a wide range of bacterial infections including acute sinusitis, pneumonia, H. Pylori, urinary tract infections, chronic prostatitis, and certain forms of gastroenteritis.
Levofloxacin Uses
Levofloxacin belongs to a class of antibiotics known as quinolones. It is effective against various bacterial infections but not against viral infections like the common cold or flu. Misuse or unnecessary use of antibiotics can reduce their effectiveness.

- Treating endocarditis (heart lining infection)
- Sexually transmitted infections
- Salmonella and Shigella infections (causing severe diarrhea)
- Anthrax and tuberculosis
- Preventing and treating traveler's diarrhea
