What Is Levofloxacin 500mg?
Levofloxacin is a fluoroquinolone antibiotic that works by stopping the growth of bacteria. It is the generic form of the brand-name drug Levaquin and is FDA-approved to treat a range of bacterial infections in adults. Levofloxacin is taken as a tablet, typically once daily, and only works against bacterial infections — not viral illnesses like colds or the flu. Because fluoroquinolones carry serious risks, it is generally reserved for infections where other antibiotics are not appropriate.
