What Roxin is used for
Roxin contains norfloxacin as the active ingredient. It belongs to a group of antibiotics called quinolones. These medicines work by killing the bacteria that is causing infection.
Roxin is an antibiotic used to treat:
- urinary tract infections
- gastrointestinal infections.
Ask your doctor if you have any questions about why Roxin has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
Roxin is available only with a doctor’s prescription.
There is no evidence that it is addictive.

Some medicines may interfere with the absorption of Roxin. These include:

Roxin may prolong the effect of coffee and other drinks containing caffeine.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking Roxin.
How to take it
How much to take
Follow all directions given to you by your doctor and pharmacist carefully.
Your doctor will tell you how many tablets you need to take each day and when to take them.
The usual dose is one tablet twice a day.
How to take it
Swallow the tablets with a glass of water.
Take Roxin on an empty stomach, one hour before or two hours after food. Food can interfere with the absorption of Roxin.
Do not take Roxin at the same time as taking iron or zinc supplements (or any multivitamins containing them), antacids, didanosine or sucralfate. Taking Roxin at the same time or even within two hours of taking these can interfere with the absorption of Roxin, so that the chance of Roxin fighting the infection won’t be as good.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do, ask your doctor or pharmacist.
How long to take it
Keep taking Roxin until you finish the pack, or for as long as your doctor recommends.
Do not stop taking Roxin, even if you feel better after a few days, unless advised by your doctor. Your infection may not clear completely if you stop taking this medicine too soon.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Roxin. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are taking it
Things you must do
Tell all the doctors, dentists and pharmacists who are treating you that you are taking Roxin, especially if you are about to start taking any new medicines.
Tell your doctor if you become pregnant while taking Roxin.
Tell your doctor or pharmacist immediately if you get severe diarrhoea. Do this even if it occurs several weeks after you have stopped taking Roxin. Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care.
Do not take any diarrhoea medicine without checking with your doctor.
Drink plenty of water or fluids while you are taking Roxin. This will help prevent crystals forming in the urine, leading to kidney problems. This side effect is very rare.
Things you must not do
Do not take Roxin to treat any other conditions unless your doctor tells you to.
Do not give Roxin to anyone else, even if they have the same condition as you.
Things to be careful of
Be careful driving or operating machinery until you know how Roxin affects you. This medicine may cause drowsiness, dizziness or lightheadedness in some people. If any of these occur, do not drive, operate machinery or do anything else that could be dangerous while taking Roxin.
Protect your skin when you are in the sun, especially between 10 am and 3 pm. If outdoors, wear protective clothing and use a 30+ sunscreen. Roxin may cause your skin to be much more sensitive to sunlight than it is normally. This may cause a skin rash, itching, redness or severe sunburn.
If your skin does appear to be burning, stop taking Roxin and tell your doctor.
Try not to consume large amounts of caffeine while you are taking Roxin. Roxin may increase the chance of you getting side effects from caffeine, such as sleeplessness, anxiety, tremor, increased heartbeat and headache. Caffeine is contained within coffee, tea, cola and energy drinks.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Roxin.
Like all other medicines, Roxin may have unwanted side effects in some people. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
- nausea, upset stomach, stomach pain
- disturbances to vision
- tiredness, changes in sleep pattern
- vaginal thrush – sore and itchy vagina or discharge.
These side effects are usually mild.
Tell your doctor as soon as possible if you notice any of the following:
- increased sensitivity of the skin to the sun, with symptoms of sunburn (redness, blistering or itching) happening more quickly than usual
- confusion, depression, hallucinations
- bleeding or bruising more easily than usual
- signs of anaemia such as tiredness, being short of breath and looking pale
- numbness or tingling in the fingers or toes
- worsening of the symptoms of myasthenia gravis
- decreased feeling or sensitivity, especially in the skin
- changes in your hearing.
These are serious side effects. You may need urgent medical attention. Serious side effects are rare.
If any of the following happen, stop taking Roxin and tell your doctor immediately, or go to Accident and Emergency at the nearest hospital:
- severe abdominal cramps or stomach cramps
- watery and severe diarrhoea, which may also be bloody
- skin rash, itching or hives or peeling or blistering of the skin

- yellowing of the skin or eyes
- frequent infections such as fever, severe chills, sore throat or mouth ulcers
- sudden and severe pain or swelling of the muscles, joints or tendons
- seizures, convulsions or fits
- passing little or no urine, blood in the urine.
These are very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are rare.
After you have finished taking it
Tell your doctor immediately if you notice any of the following, even if they occur several weeks after stopping treatment with Roxin:
- severe abdominal cramps or stomach cramps
- watery and severe diarrhoea, which may also be bloody
- fever, in combination with one or both of the above.
These are rare but serious side effects. You may have a serious condition affecting your bowel. You may need urgent medical attention. However, these side effects are rare.
Do not take any diarrhoea medicine without first checking with your doctor.
Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything that is making you feel unwell.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
After taking it
Keep your tablets in a cool dry place where the temperature stays below 30°C.
Do not store Roxin or any other medicine in the bathroom or near a sink. Do not leave it in the car or on window sills. Heat and dampness can destroy some medicines.
Keep this medicine where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
If your doctor tells you to stop taking Roxin, or your tablets have passed their expiry date, ask your pharmacist what to do with any that are left over.
