Table of contents:

Noroxin is a prescription antibiotic drug used to treat a variety of bacterial infections, such as urinary tract infections and prostatitis. It contains an active ingredient called norfloxacin. Norfloxacin belongs to the class of drugs known as fluoroquinolone antibiotics. It works by killing bacteria or preventing their growth.

Noroxin should be used only to treat bacterial infections and not for viral infections like the common cold or flu. Before using Noroxin or any other medication, consult your doctor or healthcare provider to ensure that it is safe and appropriate for you.

Uses and Dosage

Norfloxacin is available in tablet form and should be taken orally as directed by your doctor, typically twice a day (every 12 hours). Take the tablet with a full glass of water and avoid having any food or dairy products (such as milk or yogurt) within 2 hours before or 1 hour after taking Norfloxacin.

To ensure its effectiveness, take Norfloxacin at least 2 hours before or 2 hours after taking other products that may lower its effectiveness, such as quinapril, sucralfate, vitamins/minerals (including iron, zinc), and products that contain magnesium, aluminum, or calcium (such as antacids, didanosine solution, calcium-enriched juice), among others. It is advised that you speak with your pharmacist about all the products you take.

Norfloxacin may increase and/or make the effects of caffeine last longer, so avoid taking large amounts of caffeine (such as coffee or energy drinks). For the best results, take this antibiotic at the same time every day. Continue taking Norfloxacin until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.
