Two medicines, side by side

Moxifloxacin vs ciprofloxacin

Moxifloxacin and ciprofloxacin are both labeled for bacterial infections. Drugs@FDA records approvals of moxifloxacin since 1999 and of ciprofloxacin since 1987. Pharmacies paid $1.60 per mL (Moxifloxacin 0.5% eye drops) and $0.123 per ciprofloxacin HCl 500 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: Moxifloxacin, “Moxifloxacin is a member of the fluoroquinolone class of antibacterial agents [see Microbiology ( 12.4 )].”; Ciprofloxacin, “Ciprofloxacin is a member of the fluoroquinolone class of antibacterial agents [see Microbiology ( 12.4 )].”
