Two medicines, side by side

Ciprofloxacin vs levofloxacin

Ciprofloxacin and levofloxacin are both labeled for bacterial infections and urinary tract infections. Drugs@FDA records approvals of ciprofloxacin since 1987 and of levofloxacin since 1996. Pharmacies paid $0.123 per ciprofloxacin HCl 500 mg tablet and $0.259 per levofloxacin 750 mg tablet (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. Ciprofloxacin's other strengths are brand-only: $1.25 per mL (Cipro 5% suspension). How each works, in its label's words: Ciprofloxacin, “Ciprofloxacin is a member of the fluoroquinolone class of antibacterial agents [see Microbiology ( 12.4 )].”; Levofloxacin, “Levofloxacin is a member of the fluoroquinolone class of antibacterial agents [see Microbiology ( 12.4 )].”

Check it at the source: the ciprofloxacin FDA label on DailyMed (effective March 2, 2026); the levofloxacin FDA label on DailyMed (effective July 10, 2024).
