Gatifloxacin eye drops are a prescription antibiotic used to treat bacterial eye infections, such as pink eye (bacterial conjunctivitis). They work by stopping the growth of bacteria, helping to clear up the infection and reduce symptoms like redness, swelling, and discharge. Gatifloxacin is effective against a wide range of bacteria, making it a reliable treatment option. The drops are usually applied multiple times a day for several days, as prescribed by a doctor. To get the best results, it's important to use them consistently and complete the full course of treatment, even if symptoms start to improve earlier.
