Noroxin (Norfloxacin) Dosage and Side Effects

NOROXIN is used to treat different bacterial infections of the prostate or urinary tract (bladder and kidneys). NOROXIN is also used to treat gonorrhea.

Proper Use of this medication

NOROXIN is usually taken every 12 hours. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Take this medicine with a full glass of water (8 ounces). Drink several extra glasses of fluid each day while you are taking NOROXIN.

Take NOROXIN on an empty stomach 1 hour before or 2 hours after eating a meal, drinking milk, or eating a dairy product such as yogurt.

Use this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. NOROXIN will not treat a viral infection such as the common cold or flu.

If you are being treated for gonorrhea, your doctor may also have you tested for syphilis, another sexually transmitted disease.

Do not share this medication with another person (especially a child), even if they have the same symptoms you have.

Store at room temperature away from moisture and heat.
