What Inza is used for
Inza belongs to a group of medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).
Inza relieves pain and 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
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.
This medicine is available only with a doctor’s prescription.
Inza is not addictive.

Use in Children
There is no specific information available to recommend the use of Inza 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 Inza
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 Inza exactly as your doctor has prescribed.
Your doctor will tell you how many Inza tablets you need 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 the tablets whole with a full 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 Inza
Do not take Inza for longer than your doctor says.
Depending on your condition, you may need to use Inza only once, for a few days, a few weeks or for longer periods.
For sprains and strains, Inza is usually only needed for a few days.
If you are taking Inza for arthritis, it will not cure your condition but it should help to control pain, swelling and stiffness. If you have arthritis, Inza should be taken every day for as long as your doctor prescribes.
Ask your doctor if you are not sure how long to take Inza for.
If you forget to take Inza
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 continue taking it as you would normally.
Do not double a dose to make up for the dose 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 the 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 Inza.

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.

Things you must not do
Do not give Inza 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 Inza affects you.
As with other NSAID medicines, Inza may cause drowsiness or light-headedness in some people. Make sure you know how you react to Inza 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 Inza.
Inza helps most people with pain due to inflammation, but it may have unwanted side effects in a few people.

Tell your doctor if you notice anything else that is making you feel unwell, even if it is not on this list.
Ask your doctor or pharmacist if you don’t understand anything in this list.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
