Key takeaways
Moxifloxacin (Vigamox) and Ciprofloxacin (Ciloxan) are both fluoroquinolone antibiotics used to treat bacterial conjunctivitis (pink eye). However, there are some key differences between them. Moxifloxacin (Vigamox) is available in both brand-name and generic forms and is typically used three times a day for seven days. In contrast, Ciprofloxacin (Ciloxan) is available as a generic solution but its ointment form is brand-name only. Ciprofloxacin (Ciloxan) also treats corneal ulcers, requiring a more frequent dosing schedule, especially in the initial days of treatment. While both medications can cause eye irritation, Moxifloxacin (Vigamox) side effects include dry eye and blurry vision, whereas Ciprofloxacin (Ciloxan) can cause a white substance to form on corneal ulcers and a bad taste right after use. Both medications should not be used with contact lenses during treatment.
