I've been using Zymar for 12 days and the eye infection is not completely gone. It's about 95% healed. Since " prolonged use may result in overgrowth of nonsusceptible organisms, including fungi.", I would like to know if I should continue for a few more days or stop. Knowing that stopping antibiotics before complete recovery is risky, as the creation of "super-bugs" can be difficult to treat. Thus, I would like your opinion as to what time period is considered "prolonged" and/or any experience of using Zymar for more than 12 days.
