Note: This information is intended to help you understand your medicine and is not a substitute for advice from a healthcare professional.

Basic Product Information

• Generic name: Etoricoxib
• Medicinal class: Selective COX-2 inhibitor (NSAID)
• Common strengths: Often supplied in tablet strengths such as 30 mg, 60 mg, 90 mg, and 120 mg (availability can vary by brand and supply).
• What it’s used for: Reducing pain and inflammation in conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute gout flares (as directed by local guidance).
• How it’s taken: Usually once daily by mouth, depending on the condition and prescribed dose.

How Etoricoxib Works (Mechanism of Action)

Etoricoxib helps relieve pain and inflammation by affecting enzymes involved in producing prostaglandins—chemicals in the body that contribute to pain, fever, and inflammation.

More specifically:

• Etoricoxib selectively inhibits COX-2 (cyclooxygenase-2), an enzyme linked to inflammation and pain.
• By reducing COX-2 activity, it can decrease prostaglandin production in tissues.
• Because it is more selective for COX-2 than some older NSAIDs, it may have a different gastrointestinal (stomach) side-effect profile (though stomach and bowel risks are still possible).

Pharmacokinetics (How the Body Handles It)

Pharmacokinetics describes what the body does to a medicine—how it is absorbed, processed, and eliminated.

• Absorption: Etoricoxib is absorbed after oral dosing, with peak blood levels typically occurring within about 1 hour (timing can vary among individuals).
• Food effects: Food may slow the time to peak concentration, but the overall extent of absorption is generally similar.
• Distribution: It circulates in the bloodstream and distributes into tissues where pain and inflammation occur.
• Metabolism: Primarily processed by the liver via metabolic pathways (including CYP enzymes).
• Elimination: Metabolites are removed mainly through the kidneys (and partially through other routes).
• Half-life: The medicine stays in the body long enough to support once-daily dosing for many indications.

Typical Uses in Adults

Etoricoxib is used to treat pain and inflammation related to common musculoskeletal conditions. Indications may vary by product and local regulatory status, but commonly include:

• Osteoarthritis: Helps with joint pain and stiffness.
• Rheumatoid arthritis: Helps reduce symptoms related to inflammatory joint disease.
• Ankylosing spondylitis: Helps relieve pain and inflammation in the spine and large joints.
• Acute gout: May be used for short-term flare relief as directed by healthcare advice.

Important: The best choice of medicine depends on your age, medical history (including heart, stomach, kidney, and liver health), current medications, and the severity of symptoms.

When to Take It (Timing & Missed Dose)

Etoricoxib is typically taken once daily. Many people find it easiest to take it at the same time each day.

Timing

• Same time each day: Helps maintain consistent effect.
• Onset: Some people notice relief within a few hours, while others may take longer.
• Duration: Use for the shortest time at the lowest effective dose, especially for higher-strength regimens.

If you miss a dose

• Take it when you remember if it’s not close to the next dose.
• If it’s almost time for the next dose, skip the missed dose.
• Do not take a double dose to make up for a missed tablet.

Food Interactions

Food can influence how quickly etoricoxib reaches peak levels:

• With food: Taking it after a meal may delay peak concentration, but total absorption is usually not significantly changed.
• On an empty stomach: Peak effect may occur somewhat faster.

Practical tip: If you get any stomach discomfort, taking etoricoxib with food (or after a meal) may improve comfort for some people.

Alcohol & Medicine Interactions

Alcohol

Combining etoricoxib with alcohol may increase the risk of stomach irritation, bleeding, and liver stress in some people.

• If you choose to drink alcohol, do so cautiously and in moderation.
• Avoid heavy or binge drinking while taking NSAIDs.
• Seek medical advice if you have a history of ulcers, gastrointestinal bleeding, liver disease, or are taking blood thinners.

Common medicine interactions

Etoricoxib can interact with other medicines, particularly those affecting the kidneys, blood pressure, bleeding risk, or heart risk. Discuss all medicines and supplements with your healthcare provider, including:

• Other NSAIDs (e.g., ibuprofen, naproxen, diclofenac): Avoid combining unless specifically advised, due to added risk.
• Low-dose aspirin: Some patients use aspirin for cardiovascular protection. Do not stop or start aspirin without medical advice.
• Blood thinners (e.g., warfarin): May increase bleeding risk. Monitoring may be required.
• Antihypertensives (blood pressure medicines): NSAIDs can reduce the effectiveness of some blood pressure treatments and may raise blood pressure in some people.
• ACE inhibitors / ARBs (e.g., enalapril, lisinopril, losartan, valsartan): Can increase kidney-related risks when combined with NSAIDs, especially if dehydrated.
• Diuretics (e.g., hydrochlorothiazide, furosemide): Combined use can raise risk of kidney strain.
• Selective serotonin reuptake inhibitors (SSRIs) or SNRIs: May increase gastrointestinal bleeding risk when combined with NSAIDs.
• Lithium: Levels may rise, increasing toxicity risk.
• Methotrexate: Interactions can occur, particularly at higher doses.
• Cyclosporine / tacrolimus: May increase kidney risk.

Always check: If you’re unsure whether a medicine is an NSAID or could interact, ask a pharmacist.

Indications & Dosing (General Guidance)

Doses depend on the condition, age, risk factors, and the strength available. Your healthcare professional should tailor the dose to you.

Below is general typical dosing information used in practice. Exact dosing can vary and should follow local prescribing guidance and product information.

Special risk groups: People with certain liver conditions, older age, cardiovascular risk, history of ulcers/bleeding, or kidney impairment may require different dosing or avoidance.

Do not change your dose without professional advice.

Safety Profile (Who Should Be Careful)

Like other NSAIDs, etoricoxib can cause side effects. While many people tolerate it well, it’s important to know potential risks, particularly involving the heart, blood pressure, stomach, kidneys, and liver.

Common side effects

• Headache
• Dizziness
• Fluid retention or swelling (oedema)
• Stomach discomfort, heartburn, or nausea
• In some people, increased blood pressure

Serious side effects — seek urgent medical attention

• Signs of a heart problem: chest pain, shortness of breath, sudden weakness, or trouble speaking
• Signs of stomach or bowel bleeding: vomiting blood, black/tarry stools, or unexplained severe abdominal pain
• Signs of allergic reaction: swelling of face/lips, wheezing, rash, or difficulty breathing
• Signs of liver injury: yellowing of skin/eyes, dark urine, severe fatigue, or persistent nausea
• Signs of kidney problems: reduced urination, sudden weight gain from fluid retention, or severe fatigue

Cardiovascular risk considerations

COX-2 inhibitors can carry an increased risk of cardiovascular events (such as heart attack and stroke), especially at higher doses or in people with established cardiovascular disease or significant risk factors.

• Use the lowest effective dose and the shortest possible duration.
• People with prior heart disease or stroke require careful evaluation by a healthcare professional.

Stomach and bleeding risk

NSAIDs can increase the risk of ulcers and gastrointestinal bleeding. COX-2 selectivity may reduce risk compared with some non-selective NSAIDs, but risk is not eliminated.

• Higher risk if you have a history of stomach ulcers or bleeding.
• Risk may increase with age or concurrent use of certain medicines (e.g., blood thinners, steroids, SSRIs/SNRIs).

Kidney and fluid balance

Etoricoxib can affect kidney function, particularly in dehydrated individuals or those with pre-existing kidney issues.

• Stay well hydrated unless your doctor has restricted fluids.
• Seek advice if you have reduced urination or swelling.

Liver considerations

Etoricoxib is metabolised by the liver. If you have liver disease, dosing may need modification.

Practical Use Tips (Getting the Best Results Safely)

• Use the lowest effective dose: This can help reduce risk while improving symptom control.
• Take consistently: Once-daily dosing works best when taken at about the same time each day.
• Consider meal timing: If your stomach feels unsettled, take it with food.
• Avoid doubling up: Don’t combine with other NSAIDs unless explicitly advised.
• Monitor your blood pressure: If you have hypertension, ask your pharmacist or GP for guidance.
• Be cautious with dehydration: Illness, vomiting, or hot weather can increase kidney risk.
• Keep track of symptom relief: If pain isn’t improving, review the plan with your healthcare professional.

Alternative Options for Pain and Inflammation

Depending on your condition and risk factors, alternatives to etoricoxib may include other medication classes and non-drug approaches.

Medication alternatives

• Other NSAIDs (non-selective), such as ibuprofen or naproxen (choice depends on your stomach, kidney, and cardiovascular risk).
• Paracetamol (acetaminophen) for pain control, sometimes used alongside other therapies depending on advice.
• Topical NSAIDs (e.g., diclofenac gel) for certain joint pains, which may reduce systemic exposure.
• Disease-modifying treatments for inflammatory arthritis (e.g., DMARDs) managed by a specialist—these address the underlying condition rather than just symptom relief.

Non-medicine approaches

• Physiotherapy and exercise tailored to your condition
• Weight management for osteoarthritis where applicable
• Heat/cold therapy
• Joint protection strategies and activity pacing

Your pharmacist can help compare options based on your medical history and other medicines.
