What is Arcoxia?
Arcoxia is used for the following:
- acute and chronic treatment of the signs and symptoms of osteoarthritis and rheumatoid arthritis
- management of ankylosing spondylitis
- relief of chronic musculoskeletal pain
- relief of acute pain
- to treat acute gouty arthritis
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.
Arcoxia
Generic Name: etoricoxib
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.

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.

- you have a history of stroke or mini stroke
- you have conditions which increase your risk of coronary artery disease or atherosclerosis such as high blood pressure, diabetes, high cholesterol or smoking.

Some medicines and Arcoxia may interfere with each other. These include:
- warfarin, a medicine used to prevent blood clots
- rifampicin, an antibiotic used to treat tuberculosis and other infections
- water pills (diuretics)
- ACE inhibitors and angiotensin receptor blockers, medicines used to lower high blood pressure or treat heart failure
- lithium, a medicine used to treat a certain type of depression
- birth control pills
- hormone replacement therapy
- methotrexate, a medicine used to suppress the immune system
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.

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.
