Key takeaways
Moxifloxacin (Vigamox) and Besifloxacin (Besivance) are both fluoroquinolone antibiotic eye drops used to treat bacterial conjunctivitis (pink eye). Moxifloxacin (Vigamox) is available in both brand-name and generic forms, while Besifloxacin (Besivance) is only available as a brand-name medication. Moxifloxacin (Vigamox) can be used in people of all ages, including infants, whereas Besifloxacin (Besivance) is approved for use in adults and children 1 year and older. Both medications are typically dosed as one drop in the affected eye(s) three times a day for seven days. Common side effects for both include eye redness and irritation, but Moxifloxacin (Vigamox) can also cause dry eye, blurry vision, and watery eyes. While both medications are effective, the choice between them may depend on age and specific bacterial coverage.
