Ofloxacin is an antibiotic used to treat bacterial infections, which can sometimes cause stomach pain. If your doctor suspects a bacterial gut infection, this is the correct medication. However, for typical post-meal pain like acid reflux, antibiotics are not standard, so it is best to confirm the diagnosis with your doctor. Take this medication exactly as directed, usually with a full glass of water. You can take it with or without food, but avoid dairy products, antacids, or multivitamins containing iron or zinc for two hours before or after taking it, as they can reduce its effectiveness. Always complete the entire course.
