This leaflet answers some common questions about NAPROSYN tablets.
It does not contain all the available information.
It does not take the place of talking to your doctor or pharmacist.

What NAPROSYN is used for
NAPROSYN belongs to a group of medicines called Non-Steroidal Anti-Inflammatory Drugs (or NSAIDs).
NAPROSYN relieves pain and reduces inflammation (swelling, redness and soreness) that may occur in the following:
- in different types of arthritis including rheumatoid arthritis, osteoarthritis and ankylosing spondylitis
- in muscle and bone injuries such as sprains, strains, lower back pain (lumbago), rheumatism and tendonitis, such as tennis elbow
- swelling and pain after setting broken or dislocated bones
- menstrual cramps (period pain)
- headache, including migraines
- following surgery
- dental pain
Although NAPROSYN can relieve the symptoms of pain and inflammation, it will not cure your condition.
Your doctor may have prescribed NAPROSYN for another reason.
Ask your doctor if you have any questions why NAPROSYN has been prescribed for you.
This medicine is available only with a doctor's prescription.
NAPROSYN is not addictive.
Before you take NAPROSYN
When you must not take it
Do not take NAPROSYN if you have an allergy to:
- NAPROSYN or any ingredients listed at the end of this leaflet
- aspirin or any other NSAID medicine
Many medicines used to treat headache, period pain and other aches and pains contain aspirin or NSAID medicines. If you are not sure if you are taking any of these medicines, ask your pharmacist.
Symptoms of an allergic reaction to these medicines may include:
- asthma, wheezing or shortness of breath
- swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing
- hives, itching or skin rash
If you are allergic to aspirin or NSAID medicines and take NAPROSYN, these symptoms may be severe.
Do not take NAPROSYN if:
- you are vomiting blood or material that looks like coffee grounds
- you are bleeding from the rectum (back passage), have black sticky bowel motions (stools) or bloody diarrhoea
- you currently have a peptic ulcer (i.e. stomach or duodenal ulcer), or have had one before
- you have severe liver disease
- you have recently had or are about to have heart bypass surgery
- you are taking other medications which contain naproxen or naproxen sodium (e.g. Naprogesic®, Anaprox® or Inza®)
- you have severe heart failure
Do not give NAPROSYN to a child under the age of 2 years The safety and effectiveness of NAPROSYN in children under 2 years of age has not been established.
Do not take NAPROSYN if the package is torn or shows signs of tampering.
Do not take NAPROSYN if the expiry date (EXP) printed on the pack has passed. If you take this medicine after the expiry date has passed, it may not work as well.
If you are not sure if you should start taking NAPROSYN, talk to your doctor.
Before you start to take it
Tell your doctor if:
- you have any allergies to:
- any other medicines including aspirin or other NSAID medicines
- any other substances, such as foods, preservatives or dyes
- you are pregnant or intend to become pregnant
NAPROSYN may impair fertility and is not recommended in women attempting to conceive. NAPROSYN may affect your developing baby if you take it during pregnancy.
If it is necessary for you to take NAPROSYN, your doctor will discuss the risks and benefits of taking it during pregnancy.
- you are breast-feeding or intend to breast-feed
NAPROSYN passes into breast milk. The effect on the baby is not known.
- you have or have had any medical conditions, especially the following:
- heartburn, indigestion, stomach ulcers or other stomach problems
- vomiting blood or bleeding from the back passage
- bowel or intestinal problems such as ulcerative colitis
- kidney or liver disease
- heart failure
- high blood pressure or heart problems
- swelling of the ankles or feet
- a tendency to bleed or other blood problems, such as anaemia
- you currently have an infection
If you take NAPROSYN while you have an infection, the signs may be hidden (e.g. pain, fever). This may make you think, mistakenly, that you are better or that it is not serious.
- you plan to have surgery
NAPROSYN can prolong bleeding.
If you have not told your doctor about any of the above, tell them before you take any NAPROSYN.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking NAPROSYN.
Ask your doctor or pharmacist if you are not sure about this list of medicines.
Use in Children
There is no specific information available to recommend the use of NAPROSYN in children under 5 years.
Use in People Over 65 Years
Older people may be at more risk of developing stomach ulcers and hence your doctor may prescribe a lower dose.
How to take NAPROSYN
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
How much to take
Take NAPROSYN exactly as your doctor has prescribed. Your doctor will tell you how many NAPROSYN tablets to take each day. If you are an older patient, your doctor may give you a lower dose.
Sprains, strains and period pain
The recommended dose is 500 mg given initially, then 250 mg every 6 to 8 hours as needed. The total dose in one day should not exceed 1250 mg.
The recommended dose is 750 mg taken at the first sign of a migraine. An additional dose of 250 mg to 500 mg can be taken at least an hour after the initial dose, if required. The total dose in one day should not exceed 1250 mg.
The recommended dose is 375 mg to 1000 mg a day, divided in two doses.
How to take it
Swallow NAPROSYN tablets whole with a glass of water or milk.
When to take it
Take the tablets during or immediately after food with a full glass of water or milk. This may help reduce the possibility of an upset stomach.
How long to take NAPROSYN
Do not take NAPROSYN for longer than your doctor says.
Depending on your condition, you may need to use NAPROSYN, only once, for a few days, a few weeks or for longer periods.
For sprains and strains, NAPROSYN is usually only needed for a few days.
If you are taking NAPROSYN for arthritis, it will not cure your condition but it should help to control pain, swelling and stiffness. If you have arthritis, NAPROSYN should be taken every day for as long as your doctor prescribes.
Ask your doctor if you are not sure how long to take NAPROSYN for.
If you forget to take NAPROSYN
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 it as soon as you remember and then continue taking it as you would normally.
Do not double a dose to make up for one you have missed.
If you have trouble remembering your dose, ask your pharmacist for some hints.
If you are not sure what to do, ask your doctor or pharmacist.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much NAPROSYN. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much NAPROSYN, you may experience drowsiness, pain or tenderness in the stomach, stomach upset including nausea (feeling sick), vomiting, heartburn, indigestion or cramps.
While you are taking NAPROSYN

If you get an infection while using NAPROSYN, tell your doctor. NAPROSYN may hide some of the signs of an infection and may make you think, mistakenly, that you are better or that it is not serious. Signs of an infection may include fever, pain, swelling and redness.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.
Tell your doctor if you feel the tablets are not helping your condition.
Things you must not do

Things to be careful of
Be careful driving or operating machinery until you know how NAPROSYN affects you.
As with other NSAID medicines, NAPROSYN may cause dizziness or light-headedness in some people. Make sure you know how you react to NAPROSYN before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed. If this occurs do not drive. If you drink alcohol, dizziness or light-headedness may be worse.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking NAPROSYN.
