What ARTHREXIN is used for
ARTHREXIN contains the active ingredient, indometacin. It belongs to a group of medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).
ARTHREXIN is used to relieve pain and reduce inflammation (swelling, redness and soreness) that may occur in the following conditions:
different types of arthritis including rheumatoid arthritis, osteoarthritis, gouty arthritis, ankylosing spondylitis and degenerative joint disease of the hip
muscle and bone injuries such as sprains, strains, low back pain (lumbago) and tendonitis, such as tennis elbow
pain and swelling after setting broken or dislocated bones
menstrual cramps (period pain)
Although ARTHREXIN can relieve the symptoms of pain and inflammation, it will not cure your condition.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is not addictive.
It is available only with a doctor's prescription.
There is not enough information to recommend the use of this medicine for children under the age of 2 years.
Before you take ARTHREXIN
When you must not take it
Do not take ARTHREXIN if you have an allergy to:
any medicine containing indometacin
aspirin or any other NSAID medicines
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 other NSAID medicines.
If you are not sure if you are taking any of these medicines, ask your doctor or pharmacist.
Some of the symptoms of an allergic reaction may include:
shortness of breath
wheezing or difficulty breathing
swelling of the face, lips, tongue or other parts of the body
rash, itching or hives on the skin
If you are allergic to aspirin or NSAID medicines and use ARTHREXIN, the above symptoms may be severe.
Do not take this medicine if you are pregnant or intend to become pregnant.
The safety of this medicine during pregnancy has not been established.
Do not breastfeed if you are taking this medicine.
The active ingredient in ARTHREXIN passes into breast milk and there is a possibility that your baby may be affected.
Do not take ARTHREXIN if:
you have an active peptic ulcer (i.e. a stomach or duodenal ulcer) or have had peptic ulcers more than once before
you have severe heart failure
you have recently had heart bypass surgery
you have severe liver failure
you experience asthma attacks, hives or rash or itching of the nose, throat or eyes with aspirin or other NSAIDs

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 have allergies to any other medicines, foods, dyes or preservatives.

heartburn or indigestion
history of swelling in the feet or ankles

Tell your doctor if you currently have an infection.
ARTHREXIN may hide some of the signs of an infection. This may make you think, mistakenly, that you are better or that it is less serious than it might be.
Signs of an infection include fever, pain, swelling or redness.
If you have not told your doctor about any of the above, tell them before you start taking ARTHREXIN.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

aspirin, salicylates or other NSAID medicines (e.g. ibuprofen)
anticoagulants such as warfarin, a medicine used to prevent blood clots
digoxin, a medicine used to treat heart failure or irregular heart beats
lithium, a medicine used to treat mood swings and some types of depression
probenecid, a medicine used to treat gout
diuretics, also known as fluid or water tablets
some medicines used to treat high blood pressure or heart conditions, including ACE inhibitors or betablockers or medicines used in combination with a thiazide diuretic
ciclosporin, a medicine used to prevent organ transplant rejection or suppress the immune system
methotrexate, a medicine used to treat arthritis and certain types of cancers

Use in the elderly
Elderly patients may be more sensitive to the effects or side effects of this medicine.
How to take ARTHREXIN
Follow all directions given to you by your doctor and pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box/bottle, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how many capsules you need to take each day. The dose will depend on the condition being treated and your response to the treatment. Your initial dose will be maintained or adjusted until a satisfactory response is noted.
The dose varies from patient to patient. The usual dose is between 50 mg and 200 mg per day, given in divided doses.
Elderly patients may need smaller doses.
Tell your doctor of any changes in your condition, as you may require a change in the dose of ARTHREXIN.
The dose for menstrual cramps (period pain) is usually one 25 mg capsule every eight hours, starting with the onset of bleeding or cramps.
How to take it
Swallow the capsules whole with a full glass of water.
ARTHREXIN may also be taken with an antacid, if advised by your doctor or pharmacist.
This may help reduce the possibility of stomach and bowel problems.
When to take it
Take ARTHREXIN with or immediately after food.
How long to take it
Continue taking your medicine for as long as your doctor tells you to.
Depending on your condition, you may need this medicine for a few days, a few weeks or for longer periods.
As with other NSAID medicines, if you are using ARTHREXIN for arthritis, it will not cure your condition but it should help to control pain, swelling and stiffness. If you have arthritis, ARTHREXIN should be taken every day for as long as your doctor prescribes.
For sprains and strains, ARTHREXIN is usually only needed for a few days.
For gout, ARTHREXIN can be stopped when the joint pain disappears.
For menstrual cramps, ARTHREXIN should be taken at the start of bleeding or cramps and continued for as long as the cramps last.
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 it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
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 ARTHREXIN. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
Symptoms of an overdose may include nausea, vomiting, headache, dizziness, confusion, fatigue, numbness or fits.
