Note: Arcoxia has not been approved by the FDA for the U.S. market. The manufacturer of Arcoxia received a non-approvalable letter from the FDA in April of 2007. This non-approvable letter was due to safety concerns of an increased risk of cardiovascular events (including heart attack and stroke) and questions on the benefit-risk ratio in patients taking Arcoxia. Merck will continue to market Arcoxia outside the United States.

What is Arcoxia?

Arcoxia is used for the following:

Your doctor will prescribe Arcoxia for you only after you have used other medicines for your condition and they have not been suitable for you.

Your doctor will want discuss your treatment with Arcoxia from time to time. It is important that you use the lowest dose that controls your pain and you should not take Arcoxia for longer than necessary. This is because the risk of heart attacks and strokes might increase after prolonged treatment, especially with high doses.

Osteoarthritis

Osteoarthritis is a joint disease. It results from the gradual breakdown of the cartilage that covers the joints and cushions the ends of bones.

Symptoms of osteoarthritis include pain, tenderness, stiffness of one or more joints, and physical disability. The hips and knees are the most commonly affected joints, but other joints such as those of the hands and spine may also be affected.

Osteoarthritis is more common in women than in men. Many factors can lead to the development of osteoarthritis including obesity and joint injury (eg. from sport).

Rheumatoid Arthritis

Rheumatoid arthritis is a chronic disease that causes pain, stiffness, swelling and loss of function in the joints and inflammation in other body organs.

Ankylosing Spondylitis

Ankylosing spondylitis is an inflammatory disease of the spine and large joints.

Gout

Gout is a disorder characterised by sudden, recurring attacks of pain and inflammation in one or more joints.

How does Arcoxia work?

Note: Arcoxia has not been approved by the FDA for the U.S. market.

Arcoxia belongs to a group of medicines called cyclooxygenase-2 (COX-2) specific inhibitors (also known as coxibs).

The body produces two similar enzymes called COX-1 and COX-2. COX-1, among other functions, is involved with protecting the stomach, while COX-2 plays a role in joint inflammation and pain.

Arcoxia reduces pain and inflammation by blocking COX-2, an enzyme in the body.

Arcoxia does not block COX-1, the enzyme involved in protecting the stomach from ulcers.

Other anti-inflammatory medicines (NSAIDS) block both COX-1 and COX-2.

Arcoxia relieves pain and inflammation with less risk of stomach ulcers compared to NSAIDS.

However taking aspirin with Arcoxia may reverse this benefit (see Before you take Arcoxia, Taking Other Medicines).

In clinical studies, the risk of developing ulcers on Arcoxia was lower than with NSAIDs. Some people developed ulcers whether they were taking Arcoxia or placebo in these studies; however the rate was higher on Arcoxia.

If any of the following symptoms: shortness of breath, chest pains or ankle swelling appear or worsen, stop your treatment with Arcoxia and consult a doctor, as soon as is practical.

If you have kidney, liver or heart disease, your doctor will want to appropriately keep a check on you.

If you develop any symptoms that could indicate a severe allergic reaction such as an inability to breathe or a serious skin reaction you must consult a doctor on an urgent basis.

Your doctor will want to discuss your treatment from time to time. It is important that you use the lowest dose that controls your pain and you should not take Arcoxia for longer than necessary. This is because the risk of heart attacks and strokes might increase after prolonged treatment, especially with high doses.

Arcoxia can increase blood pressure in some people, especially in high doses, and this could increase the risk of heart attacks and strokes. Your doctor will want to check your blood pressure from time to time, to make sure that it is safe to continue treatment.

Your doctor may have prescribed Arcoxia for another reason. Ask your doctor if you have any questions about why Arcoxia has been prescribed for you.

Arcoxia is not addictive.

Before you take Arcoxia

Note: Arcoxia has not been approved by the FDA for the U.S. market.

Do not take Arcoxia if:

If you are not sure whether you should start taking Arcoxia, talk to your doctor.

Arcoxia has not been adequately studied in children. Therefore, Arcoxia should not be given to children.

Arcoxia works equally well in older and younger adult patients. Adverse experiences may occur at a higher incidence in older patients compared to younger patients. If you are elderly (ie over 65 years of age), your doctor will want to appropriately keep a check on you. No dosage adjustment is necessary for older patients.

Before you start to taking Arcoxia tell your doctor if:

If you have not told your doctor about any of the above, tell them before you take any Arcoxia.

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and Arcoxia may interfere with each other. These include:

These medicines may be affected by Arcoxia or may affect how well it works. You may need different amounts of your medicine, or you may need to take different medicines.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking Arcoxia.

Arcoxia can be taken with low dose aspirin. If you are currently taking low dose aspirin for the prevention of a heart attack or stroke, you should continue to do so unless specified by your Doctor. Arcoxia cannot replace aspirin for this purpose.

How to take Arcoxia

Note: Arcoxia has not been approved by the FDA for the U.S. market.

Take Arcoxia only when prescribed by your doctor.

For osteoarthritis, the recommended dose is 60 mg once a day.

For rheumatoid arthritis the recommended dose is 90 mg once a day.

For ankylosing spondylitis the recommended dose is 90 mg once a day.

For the relief of gout attacks the recommended dose is 120 mg once a day, which should only be used for the acute painful period.

For the relief of chronic musculoskeletal pain the recommended dose is 60 mg once a day.

Doses greater than those recommended for each condition have either not demonstrated additional efficacy or have not been studied. Therefore, the daily doses stated above for each condition should not be exceeded.

If you have mild liver disease, you should not take more than 60 mg a day. If you have moderate liver disease, you should not take more than 60 mg every other day.

Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the box, ask your doctor or pharmacist for help. Arcoxia comes as tablets.

When taking the tablets, swallow them with a glass of water. Do not halve the tablet.

Take your Arcoxia at about the same time each day.

Taking Arcoxia at the same time each day will have the best effect. It will also help you remember when to take the dose.

It does not matter if you take Arcoxia before or after food.

Do not use Arcoxia for longer than your doctor says.

Your doctor will want to discuss your treatment from time to time. It is important that you use the lowest dose that controls your pain and you should not take Arcoxia for longer than necessary. This is because the risk of heart attacks and strokes might increase after prolonged treatment, especially with high doses.

Depending on your condition, you may need to take Arcoxia for a few days or for a longer period.

For osteoarthritis and rheumatoid arthritis Arcoxia helps relieve your symptoms but it does not cure it. Continue taking Arcoxia for as long as your doctor prescribes.

For the relief of gout attacks or other types of pain, Arcoxia is usually only needed for a few days.

If you are not sure how long to take Arcoxia, talk to your doctor.

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 tablet(s) as you would normally.

If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

Do not take a double dose to make up for the dose that you missed.

If you have trouble remembering to take your tablets, ask your pharmacist for some hints.

If you take too much Arcoxia (overdose) immediately telephone your doctor or Poison Control Center or go to the emergency department at your nearest hospital, if you think that you or anyone else may have taken too much Arcoxia. Do this even if there are no signs of discomfort or poisoning.

While you are using Arcoxia

Note: Arcoxia has not been approved by the FDA for the U.S. market.

If you become pregnant while taking Arcoxia, tell your doctor immediately.

If you get an infection while taking Arcoxia, tell your doctor. Arcoxia may hide fever and may make you think, mistakenly, that you are better or that your infection is less serious than it might be.

If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking Arcoxia.

Do not give Arcoxia to anyone else, even if they have the same condition as you.

Some self help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and for more information.

Adverse Effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Arcoxia.

Arcoxia helps most people with osteoarthritis, rheumatoid arthritis, menstrual pain, gout or other types of pain, but it may have unwanted adverse effects in a few people. All medicines can have adverse effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the adverse effects.

Ask your doctor or pharmacist to answer any questions you may have.

Other adverse effects not listed above may also occur in some patients. Tell your doctor if you notice any other effects.

Do not be alarmed by this list of possible adverse effects. You may not experience any of them.

After using Arcoxia

Note: Arcoxia has not been approved by the FDA for the U.S. market.

Keep your tablets in the blister pack until it is time to take them. If you take the tablets out of the blister pack they may not keep well.

Keep Arcoxia in a cool dry place where the temperature stays below 30 degrees C (86 degrees F). Do not store it or any other medicine in the bathroom or near a sink. Do not leave it in the car or on window sills. Heat and dampness can destroy some medicines.

Keep it where children cannot reach it. A locked cupboard at least 1.5 meters (5 feet) above the ground is a good place to store medicines.

If your doctor tells you to stop taking Arcoxia, or the tablets have passed their expiration date, ask your pharmacist what to do with any that are left over.
