What is in this leaflet

Please read this leaflet carefully before you start taking Ridaura.

This leaflet answers some of the common questions about Ridaura. It does not contain all the available information.

Reading this leaflet does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking Ridaura against the benefits this medicine is expected to have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may want to read it again.

What Ridaura is used for

Ridaura contains auranofin, a synthetic gold compound. It is used together with other treatments, such as non-steroidal anti-inflammatory drugs (NSAIDs), for active rheumatoid arthritis.

It is thought to modify the progress of active rheumatoid arthritis. Ridaura may prevent or reduce further damage to the joints. Ridaura can also reduce the inflammation in the joints.

Rheumatoid arthritis can affect most joints, but the small joints of the hands and feet are frequently affected. The joints become swollen, warm and tender. This leads to pain and loss of joint movement. Deformity occurs with time. Morning stiffness in affected joints is a common symptom of rheumatoid arthritis.

Your doctor may have prescribed this medicine for another reason.

Ask your doctor if you have questions about why it has been prescribed for you.

Ridaura is only available with a doctor’s prescription.

There is no evidence that Ridaura is addictive.

How to take Ridaura

Read the label carefully and follow all directions given to you by your doctor and pharmacist. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.

How much to take

The usual dose of Ridaura for rheumatoid arthritis is two 3 mg tablets per day.

Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take. This depends on your condition and whether or not you are taking any other medicines.

If you take the wrong dose, Ridaura may not work as well and your problem may not improve.

Take Ridaura with a full glass of water.

When to take it

Ridaura may be taken as either a single daily dose (2 tablets once a day) or twice daily (one tablet twice a day).

Take Ridaura during or immediately after a meal, at about the same time(s) each day.

How long to take it

Continue taking the medicine for as long as your doctor tells you to. It may take 3 to 4 months (or more) before Ridaura has any effect. Your doctor may decide that you should continue to use Ridaura for some time, even when your symptoms subside.

Do not stop taking Ridaura even if you begin to feel better. For best effect Ridaura must be taken regularly.

If you are unsure whether you should stop taking Ridaura, talk to your doctor or pharmacist.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take the next dose when you are meant to.

Do not try to make up for missed doses by taking more than one dose at a time. This may increase the chance of getting an unwanted side effect.

If there is still a long time to go before your next dose, take it as soon as you remember, and then go back to taking it as you would normally.

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 hints.

If you take too much (overdose)

Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26 in Australia or 0800 764 766 in New Zealand), or go to Accident and Emergency at your nearest hospital, if you think you or anyone else may have taken too much Ridaura.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of an overdose may include dizziness, headache, flushing, fast or irregular heart beat or any of the side effects mentioned below.

While you are taking it

Things you must do

If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking Ridaura. Likewise, tell any other doctors, dentists and pharmacists who are treating you that you are taking this medicine.

Keep all of your doctor’s appointments so that your progress can be checked. Treatment with Ridaura requires careful monitoring. You will have regular blood, liver and urine tests and eye examinations.

Tell your doctor promptly if you start having any unusual symptoms such as:

  • itching, rash
  • metallic taste
  • mouth ulcer, sore throat or tongue
  • easy bruising, red-purple spots on the skin
  • nose bleed or bleeding gums
  • diarrhoea
  • abnormally heavy periods in women

These are some of the possible symptoms of gold toxicity. You may need immediate medical attention.

If you are a woman, you must take measures to avoid pregnancy during treatment and for at least 6 months after stopping treatment with Ridaura. Ridaura should not be used in pregnant women because of the possible risk of birth defects.

Pregnancy must be avoided after stopping treatment because it takes some time for gold to be removed from the body.

Tell your doctor immediately if you become pregnant during treatment or within 6 months of stopping treatment. Your doctor will discuss with you the risks and options if this occurs.

Things you must not do

Do not take Ridaura to treat any other complaints unless your doctor tells you to.

Do not stop taking Ridaura or lower the dosage without checking with your doctor.

For best effect Ridaura must be taken regularly.

Things to be careful of

Protect your skin when you are in the sun, especially between 10am and 3pm. If you are outdoors, wear protective clothing and use a 30+ sunscreen. Ridaura may cause your skin to be much more sensitive to sunlight than it is normally. This could cause a skin rash, itching, redness or severe sunburn.

Talk to your doctor or pharmacist and follow their advice about drinking alcohol while being treated with Ridaura Depending on your particular medical condition and other treatments, your doctor or pharmacist may recommend you limit or stop drinking alcohol while taking Ridaura.
