Learn about Arcoxia (etoricoxib), a non-steroidal anti-inflammatory drug (NSAID) used for pain and inflammation relief in Singapore. This guide covers its uses, dosage, side effects, precautions, where to buy it, and answers frequently asked questions. Understand its effects on driving and alcohol consumption, and whether it's suitable for long-term use.
What is Arcoxia
Arcoxia is the brand name for the drug etoricoxib, a non-steroidal anti-inflammatory drug (NSAID) belonging to a specific class called COX-2 inhibitors. COX-2 inhibitors selectively target the cyclooxygenase-2 (COX-2) enzyme, which is responsible for inflammation and pain. Unlike traditional NSAIDs that inhibit both COX-1 and COX-2, Arcoxia's selective action aims to reduce pain and inflammation while minimizing potential gastrointestinal side effects associated with COX-1 inhibition.
Etoricoxib's Role in Pain and Inflammation Management
Etoricoxib works by blocking the COX-2 enzyme, thereby reducing the production of prostaglandins, which are chemicals that contribute to pain, inflammation, and fever. This targeted action makes it effective in managing various types of pain, particularly those associated with inflammatory conditions like arthritis.
Comparing Etoricoxib with Other NSAIDs
While etoricoxib offers targeted COX-2 inhibition, traditional NSAIDs like ibuprofen and naproxen inhibit both COX-1 and COX-2. COX-1 plays a role in protecting the stomach lining, so inhibiting it can increase the risk of gastrointestinal issues. Etoricoxib's selectivity aims to mitigate this risk, but it's important to note that all NSAIDs, including COX-2 inhibitors, carry some potential for gastrointestinal side effects.
Understanding the Importance of COX-2 Inhibition
The COX-2 enzyme is primarily involved in the inflammatory process, making it a key target for pain relief. By selectively inhibiting COX-2, etoricoxib aims to reduce inflammation and alleviate pain without significantly affecting COX-1's protective functions in the stomach and other tissues.
How Arcoxia Works
Arcoxia works by inhibiting the COX-2 enzyme, a key player in the body's inflammatory response. By reducing the production of prostaglandins, Arcoxia helps to alleviate pain and inflammation.
The Mechanism of COX-2 Inhibition
COX-2 enzymes are responsible for producing prostaglandins, which are lipid compounds that mediate pain, inflammation, and fever. Etoricoxib, the active ingredient in Arcoxia, selectively binds to and inhibits COX-2, thereby reducing the production of these inflammatory mediators.
The Impact on Prostaglandin Synthesis
By blocking COX-2, Arcoxia effectively reduces the synthesis of prostaglandins, which in turn diminishes pain and inflammation at the site of injury or inflammation. This targeted action is what makes Arcoxia effective in managing various pain conditions.
The Role of COX-2 in Inflammation
COX-2 is induced at sites of inflammation, making it a prime target for anti-inflammatory drugs. By selectively inhibiting COX-2, Arcoxia aims to reduce inflammation without affecting other physiological processes that rely on COX-1, such as maintaining the integrity of the stomach lining.
Enzyme | Function | Arcoxia's Effect |
COX-1 | Protects stomach lining, supports platelet function | Minimally affected |
COX-2 | Produces prostaglandins that cause inflammation and pain | Inhibited |
Uses of Arcoxia in Singapore
Osteoarthritis
Arcoxia is commonly prescribed in Singapore for the management of osteoarthritis. Osteoarthritis is a degenerative joint disease characterized by the breakdown of cartilage, leading to pain, stiffness, and reduced mobility. Etoricoxib, the active ingredient in Arcoxia, helps reduce the inflammation and pain associated with osteoarthritis, improving joint function and quality of life. It's important to note that while Arcoxia can manage symptoms, it doesn't reverse the cartilage damage or cure the disease. The dosage will vary depending on the severity of the osteoarthritis and individual patient needs. Arcoxia can be used for both short-term pain relief during flare-ups and long-term management of chronic osteoarthritis pain. Regular monitoring by a physician is recommended, especially for long-term use.
Different Stages of Osteoarthritis
Early Stage Osteoarthritis
In early-stage osteoarthritis, Arcoxia can be used intermittently to manage pain during periods of increased activity or flare-ups. It can help individuals maintain their mobility and participate in daily activities.
Moderate to Severe Osteoarthritis
In moderate to severe osteoarthritis, Arcoxia may be prescribed on a regular basis to control pain and stiffness. This can significantly improve the patient's ability to perform daily tasks and maintain a higher quality of life.
Specific Joint Involvement (e.g., Knee, Hip)
Arcoxia can be used to manage osteoarthritis pain in various joints, including the knees, hips, hands, and spine. The dosage may vary depending on the specific joint affected and the severity of the condition.
Rheumatoid Arthritis
Arcoxia is also used in the treatment of rheumatoid arthritis, a chronic inflammatory autoimmune disease affecting the joints. Etoricoxib helps to reduce the inflammation and pain associated with rheumatoid arthritis, improving joint function and slowing down the progression of joint damage. Arcoxia is often used in combination with other disease-modifying antirheumatic drugs (DMARDs) to manage rheumatoid arthritis effectively.
Impact on Inflammation and Joint Swelling
Arcoxia's anti-inflammatory properties help reduce joint swelling and tenderness in individuals with rheumatoid arthritis. This can improve their range of motion and reduce pain during daily activities.
Ankylosing Spondylitis
Ankylosing spondylitis is a chronic inflammatory disease primarily affecting the spine and sacroiliac joints. Arcoxia can be prescribed to manage the pain and stiffness associated with ankylosing spondylitis, improving mobility and quality of life.
Managing Spinal Pain and Stiffness
Arcoxia's anti-inflammatory action helps reduce inflammation in the spine and sacroiliac joints, leading to a decrease in pain and stiffness. This can improve the patient's ability to perform daily activities and maintain a more active lifestyle.
Acute Gouty Arthritis
Arcoxia is effective in managing the pain and inflammation associated with acute gouty arthritis attacks. Gout is a type of arthritis caused by the buildup of uric acid crystals in the joints. Etoricoxib can provide rapid pain relief during these acute attacks.
Short-Term Pain Relief During Gout Attacks
Arcoxia is typically prescribed for short-term use during acute gout attacks. It helps to quickly reduce pain and inflammation, allowing individuals to resume their normal activities.
Other Pain Conditions
While primarily used for arthritis and related conditions, Arcoxia can also be prescribed for the short-term management of other types of pain, such as post-operative pain and acute musculoskeletal pain.

Refills may be possible, but you will likely need to consult your doctor again. The number of refills allowed depends on your doctor's assessment and the nature of your condition.
Arcoxia and Alcohol
Mixing Arcoxia (etoricoxib) and alcohol can increase the risk of certain side effects, particularly those affecting the gastrointestinal system. While occasional, moderate alcohol consumption may not pose a significant risk for some individuals, it's generally recommended to avoid or limit alcohol intake while taking Arcoxia. This is because both alcohol and Arcoxia can irritate the stomach lining, and combining them can exacerbate this effect, potentially leading to gastritis, ulcers, or gastrointestinal bleeding.
Furthermore, both Arcoxia and alcohol can affect blood pressure. While Arcoxia may slightly elevate blood pressure in some individuals, alcohol can have varying effects, sometimes lowering and other times raising it. Combining the two can make blood pressure fluctuations more unpredictable and potentially problematic, especially for those with pre-existing hypertension.
Substance | Potential Side Effects | Combined Effect |
Arcoxia (etoricoxib) | Stomach irritation, fluid retention, increased blood pressure (in some cases) | Increased risk of gastrointestinal issues (ulcers, bleeding), unpredictable blood pressure fluctuations, increased risk of dizziness and lightheadedness, potential for liver damage with chronic combined use. |
Alcohol | Stomach irritation, dehydration, blood pressure fluctuations, dizziness, liver damage (with chronic heavy use) |
Recommendations for Safe Consumption
If you are considering consuming alcohol while taking Arcoxia, it is crucial to discuss this with your doctor or pharmacist. They can assess your individual risk factors, such as your medical history, other medications you are taking, and your typical alcohol consumption patterns, and provide personalized advice. They may recommend completely avoiding alcohol, limiting your intake to a very small amount, or suggest alternative pain relief options if necessary.
For those who choose to drink alcohol while on Arcoxia, moderation is key. Sticking to the recommended low-risk drinking guidelines is important. These guidelines typically suggest limiting intake to a certain number of standard drinks per week and per occasion, varying depending on factors like age and gender. It's also crucial to monitor for any potential side effects, such as stomach upset, dizziness, or changes in blood pressure, and report them to your healthcare provider immediately.
Remember, prioritizing your health and safety is paramount. Open communication with your healthcare team can help you make informed decisions about managing your pain and minimizing potential risks associated with combining Arcoxia and alcohol.

FAQ
Is Arcoxia a Steroid?
Arcoxia is not a steroid. It is a non-steroidal anti-inflammatory drug (NSAID) belonging to a class of drugs called COX-2 inhibitors. Steroids, also known as corticosteroids, are a different class of drugs that mimic the effects of hormones your body naturally produces. While both NSAIDs and steroids can reduce inflammation and pain, they work through different mechanisms and have different side effect profiles. Arcoxia specifically targets the COX-2 enzyme involved in inflammation, whereas steroids have a broader effect on the body's immune response.
