What is in this leaflet
This leaflet answers some common questions about Inza.
It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking Inza against the benefits they expect
it will have for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
What Inza is used for
Inza is used to treat pain and inflammation symptoms of:
different types of arthritis including rheumatoid arthritis, osteoarthritis and ankylosing spondylitis
muscle and bone injuries such as sprains, strains, lower back pain, rheumatism and tendonitis, such as tennis elbow
swelling and pain after setting broken or dislocated bones
menstrual cramps (period pain)
pain due to inflammation
headaches and migraines
Inza belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). These medicines work by relieving
pain and inflammation (swelling, redness and soreness).
Although Inza can relieve the symptoms of pain and inflammation, it will not cure your condition.
Your doctor may have prescribed Inza for another reason. Ask your doctor if you have any questions about why Inza has been
prescribed for you.
Inza is available only with a doctor's prescription.
There is no evidence that Inza is addictive.
Before you take Inza
When you must not take it
Do not take Inza if you are allergic to:
medicines containing naproxen, aspirin or any other NSAID medicine
any of the ingredients listed at the end of this leaflet.
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, difficulty in swallowing or breathing
hives, itching or skin rash
If you are allergic to aspirin or NSAID medicines and take Inza, these symptoms may be severe.
Do not take Inza if you:
have, or have had, a peptic ulcer (ulcer of the stomach or duodenum)
are vomiting blood or material that looks like coffee grounds
are bleeding from the rectum (back passage), have black sticky bowel motions (stools) or bloody diarrhoea
have severe liver disease
have chronic and severe attacks of indigestion or other stomach trouble
you have severe heart failure
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 Naprosyn)
Do not give Inza to children under 2 years of age.
The safety of Inza in this age group has not been established.
Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking this medicine, talk to your doctor.
Before you start to take it
Tell your doctor if you are allergic to:
any other medicines including aspirin or other NSAID medicines
any other substances such as foods, dyes or preservatives.
Tell your doctor if you are pregnant or plan to become pregnant.
Inza is not recommended for use during pregnancy, as it may affect your developing baby. Inza may also reduce fertility and
affect your chances of becoming pregnant.
If there is a need to consider Inza during your pregnancy your doctor will discuss the risks and benefits involved.
Tell your doctor if you are breastfeeding or wish to breastfeed.
Inza passes into breast milk. Therefore, there is a possibility that the breastfed baby may be affected. Your doctor will
discuss the risks and benefits of taking Inza when breastfeeding.
Tell your doctor if you have or have had any of the following medical conditions:
high blood pressure or heart problems
peptic ulcer (ulcer of the stomach or duodenum)
heartburn, indigestion or other stomach problems
vomiting blood or bleeding from the back passage
bowel problems, such as ulcerative colitis or Crohn's disease
a tendency to bleed or other blood problems, such as anaemia
swelling of the ankles or legs (oedema).
Tell your doctor if you plan to have surgery.
Tell your doctor if you currently have an infection.
If you take Inza while you have an infection, it may hide some of the signs of the infection (such as pain, fever, swelling
or redness). This may make you mistakenly think that you are better or that your infection is not serious.
If you have not told your doctor about any of the above, tell him/her before you start taking Inza.
Taking other medicines

supermarket or health food shop.

Your doctor will tell you how many tablets you need to take each day and when to take them. This depends on your condition
and whether or not you are taking any other medicines.

Ask your doctor if you are not sure how long to take Inza for.
