If you have bacterial conjunctivitis (pink eye) or a corneal ulcer, a healthcare provider may prescribe levofloxacin ophthalmic solution. Your dosage of this medication will depend on the type and severity of the infection being treated. Even if you feel better after a few days, finish the full course of the medication so that your infection doesn't return.

An Introduction to Dosing With Levofloxacin Ophthalmic Solution

The dose of levofloxacin ophthalmic solution (Iquix®, Quixin®) your healthcare provider recommends will depend on the type and severity of the infection being treated.
 
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
