Noroxin belongs to a group of antibiotics called “quinolones”. It is used to treat:

- Infections of the stomach or intestines, such as traveller’s diarrhoea.
- Noroxin is also used for patients who get frequent urinary tract infections. Noroxin may help stop these infections from coming back.
What you need to know about Noroxin?
- Urinary tract infections are caused by the presence of bacteria in the urinary system. The bacteria often come from the intestines where they are necessary for normal function. In women, the most common infection involves the urinary bladder and is called cystitis. In men, the infection may involve the prostate which is called prostatitis. In both men and women, the bacteria may travel up to the kidneys and infect them.
- The symptoms of a urinary tract infection may include an urge to urinate frequently and in small amounts, and painful burning when passing urine. Urinary tract infections should be treated to avoid the kidneys being infected. Noroxin works by killing the bacteria causing these infections.
- Noroxin is not recommended to treat urinary tract infections in children or growing adolescents, as the safety of norfloxacin has not been adequately studied in this group of patients.
- Your doctor may have prescribed Noroxin for another reason. Ask your doctor if you have any questions about why Noroxin has been prescribed for you.
- There is no evidence that Noroxin is additive.
- Noroxin is available only with a doctor’s prescription.

How to take Noroxin

How much to take Noroxin: The usual dose of Noroxin is one tablet twice a day.

When to take Noroxin: Take your Noroxin about twelve hours apart. Taking Noroxin at evenly spaced times ensures that there is a reasonably constant amount in the blood and urine. This means that the medicine will fight the infection more effectively.
Take Noroxin on an empty stomach, at least one hour before food or two hours after food. This will make sure the tablets will have a better chance of fighting the infection, because food can interfere with the absorption of norfloxacin.
