What is Arcoxia?
Arcoxia is a prescription-strength medicine containing the active ingredient etoricoxib. It belongs to a specific class of non-steroidal anti-inflammatory drugs (NSAIDs) known as highly selective COX-2 inhibitors.
Unlike standard painkillers, Arcoxia is designed to target inflammation and pain with high precision. Medical professionals in Malaysia frequently prescribe it to manage both acute flare-ups and long-term joint pain, ensuring patients can maintain their daily mobility without overwhelming discomfort. Because it is a prescription-only medicine (POM), it must be dispensed by a registered pharmacist or doctor after a clinical evaluation.
Common Uses of Arcoxia
Arcoxia is typically prescribed to treat various painful inflammatory conditions. Whether you are dealing with a sudden injury or a chronic orthopaedic condition, your doctor might recommend it for the following issues:
- Osteoarthritis (OA) and Rheumatoid Arthritis (RA): Provides ongoing relief for acute and chronic joint pain, stiffness, and swelling.
- Ankylosing Spondylitis: Helps manage inflammation in the spine and large joints.
- Acute Gouty Arthritis: Used to quickly reduce the intense pain and sudden swelling associated with gout attacks.
- Primary Dysmenorrhoea: Offers relief for severe menstrual cramps that do not respond well to basic over-the-counter painkillers.
- Post-operative Dental Pain: Provides moderate to severe pain relief following dental surgeries or procedures, usually prescribed for a very short duration.
How Does Arcoxia Work?
Arcoxia works by selectively inhibiting the cyclooxygenase-2 (COX-2) enzyme in the body. By blocking this specific enzyme, it significantly reduces the production of prostaglandins—the chemical messengers responsible for triggering pain, fever, and inflammation.
The key advantage of Arcoxia lies in its selectivity. Traditional NSAIDs block both COX-1 (which protects the stomach lining) and COX-2 enzymes. By selectively targeting only COX-2, Arcoxia provides potent anti-inflammatory benefits while potentially lowering the risk of gastrointestinal toxicity and stomach ulcers compared to older, non-selective NSAIDs.
Recommended Dosage and Strengths in Malaysia
In Malaysia, Arcoxia is generally available in tablet strengths of 60mg, 90mg, and 120mg. The exact dosage depends strictly on the medical condition being treated and your doctor’s assessment. It must be swallowed whole with a glass of water and can be taken with or without food.
Below is a general guideline for the typical recommended dosages:
| Medical Condition |
Recommended Dosage |
Maximum Duration / Notes |
| Osteoarthritis |
30mg to 60mg once daily |
Use the lowest effective dose for symptom relief. |
| Rheumatoid Arthritis & Ankylosing Spondylitis |
60mg to 90mg once daily |
May be adjusted based on clinical response. |
| Post-operative Dental Pain |
90mg once daily |
Maximum of 3 days. |
| Acute Gouty Arthritis & Severe Acute Pain |
120mg once daily |
Maximum of 8 days during the acute symptomatic period. |
| Primary Dysmenorrhoea |
120mg once daily |
Maximum of 8 days during acute pain. |
Note: You must follow your doctor’s exact instructions. Taking a higher dose than recommended does not guarantee faster relief but significantly increases the risk of adverse effects.
Potential Side Effects
Like all medications, Arcoxia can cause side effects, although not everyone will experience them. Being aware of these symptoms helps you know when to seek medical advice.
Common side effects include:
- Headaches and dizziness
- Stomach discomfort, indigestion, or nausea
- Swelling in the legs, ankles, or feet (oedema) due to fluid retention
- Elevated blood pressure (hypertension), which requires regular monitoring during treatment
Severe risks to watch out for:
- Cardiovascular issues: Increased risk of heart-related events if taken at high doses over a long period.
- Gastrointestinal complications: Peptic ulcer disease or severe stomach bleeding (though less common than with traditional NSAIDs).
- Liver issues: Signs of jaundice (yellowing of the skin or eyes) or abnormal liver function tests, which require immediate medical attention.
Important Warnings and Precautions
Certain individuals should avoid taking Arcoxia or require careful medical supervision. Always disclose your full medical history to your doctor before starting treatment.
- Pregnancy and Breastfeeding: Arcoxia is strictly contraindicated during pregnancy, particularly in the third trimester, as it may harm the unborn baby. It is also not recommended for women who are actively trying to conceive or who are breastfeeding.
- Cardiovascular History: Inform your doctor if you have a history of heart disease, stroke, or uncontrolled high blood pressure. Arcoxia is generally contraindicated for patients with established ischaemic heart disease or those who have recently undergone bypass surgery.
- Stomach and Liver/Kidney Impairment: Patients with active stomach ulcers or gastrointestinal bleeding should avoid this drug. Dosage adjustments or alternative treatments may be necessary for those with mild to moderate hepatic (liver) or renal (kidney) issues.
- Drug Interactions: Arcoxia may interact negatively with ACE inhibitors (blood pressure medication), blood thinners (like warfarin), and other NSAIDs or aspirin.
- Alcohol Consumption: Alcohol should be severely limited or avoided entirely while taking Arcoxia to prevent exacerbated stomach irritation, liver strain, and severe dizziness.

Frequently Asked Questions
Do I need a prescription to buy Arcoxia in Malaysia?
Yes. In Malaysia, Arcoxia (etoricoxib) is classified as a prescription-only medicine (POM). This means you cannot buy it over the counter; it requires a valid prescription and consultation with a registered doctor or pharmacist to ensure it is safe for your specific health condition.
Can I take Arcoxia on an empty stomach?
Yes, Arcoxia can be taken with or without food. Taking it without food might allow the medication to work slightly faster, making it convenient for acute pain relief, though taking it with meals can help those who have sensitive stomachs.
What should I do if I miss a dose?
If you miss a dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and resume your normal dosing schedule. Never double up or take two doses at the same time to make up for a missed one.
Is Arcoxia safe for long-term use?
Arcoxia is generally prescribed at the lowest effective dose for the shortest duration necessary to control symptoms. Prolonged use, especially at higher doses, can increase the risk of cardiovascular and gastrointestinal side effects. Long-term use requires strict medical supervision and regular check-ups.
