Applies to: Noroxin (norfloxacin)

You should take norfloxacin on an empty stomach at least one hour before or two hours after eating a meal or consuming milk or other dairy products. Do not use mineral supplements, multivitamins, antacids, or other products that may contain calcium, iron, magnesium or zinc within the two-hour period before or after taking norfloxacin. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.
