Etoricoxib

What is Etoricoxib?

Etoricoxib is a nonsteroidal anti-inflammatory drug (NSAID) in a subgroup called COX-2 inhibitors (or “coxibs”). It helps reduce pain, swelling, stiffness, and inflammation. The best-known brand name is Arcoxia, and generic versions are sold in some countries.

Etoricoxib is approved in many countries in Europe, Asia, and Latin America. It is not approved by the U.S. Food and Drug Administration (FDA) and is not sold as a marketed medicine in the United States. Approved uses and rules for sale depend on each country’s health authority.

Approved Uses

Where it is approved, etoricoxib is used to relieve the symptoms of:

• Osteoarthritis
• Rheumatoid arthritis
• Ankylosing spondylitis (a type of arthritis that mainly affects the spine)
• Acute gouty arthritis (a gout flare)
• Short-term pain after dental surgery, in some countries

Other Common Uses

In some countries, doctors also prescribe etoricoxib for menstrual pain or short-term musculoskeletal pain. These uses depend on local approval and should always be directed by a licensed medical specialist.

Available Forms and Strengths

Form	Common Strengths	Notes
Film-coated tablets	30 mg, 60 mg, 90 mg, 120 mg	Usually taken once a day

Available strengths differ by country and manufacturer. The 120 mg strength is generally meant for short-term use in acute conditions only. Always check the label on your pharmacy package.

What is the Recommended Dosage of Etoricoxib?

The right dose is different for each person. A licensed medical specialist will decide the dose based on several factors:

• Condition being treated: Dosing for arthritis is different from dosing for a gout flare or short-term pain.
• Age: Etoricoxib is not recommended for children and adolescents under 16. Older adults are often started on lower doses.
• Kidney and liver function: People with reduced kidney or liver function may need a lower dose or may need to avoid etoricoxib.
• Heart and blood pressure health: Blood pressure and heart disease can affect whether etoricoxib is a safe choice.
• Other health conditions and medicines: Stomach problems and other medications can affect the choice of dose.

Key Safety Points About Dosing

• Take etoricoxib exactly as prescribed. Do not change your dose or schedule on your own.
• The goal is to use the lowest effective dose for the shortest time needed. Doses higher than the one prescribed for your condition have not been shown to work better and may raise the risk of side effects.
• Swallow tablets whole with water.
• Tablets are usually taken once a day, at about the same time each day. Food may delay how quickly it starts to work, so your doctor may advise taking it with or without food depending on your needs.
• Do not take other NSAIDs, such as ibuprofen, naproxen, or diclofenac, unless your specialist tells you to.

Exact doses are not listed here because they must be set for each individual. Confirm your dose with your prescriber or pharmacist.

How Etoricoxib Works

The body makes natural chemicals called prostaglandins. They play a role in causing pain, swelling, and inflammation. Enzymes called COX-1 and COX-2 help make prostaglandins.

Traditional NSAIDs block both enzymes. Etoricoxib mainly blocks COX-2, the enzyme most involved in inflammation and pain. Because COX-1 helps protect the stomach lining, etoricoxib may cause fewer stomach problems than some traditional NSAIDs in some people, but it does not remove that risk completely.

Important points to understand:

• Etoricoxib manages symptoms. It does not cure arthritis, gout, or repair joint damage.
• Etoricoxib does not have the same effect on platelets as traditional NSAIDs, so it does not provide the heart-protective effect of aspirin.
• Pain relief may begin within hours in acute conditions, while arthritis symptoms may take longer to improve.

Is a Prescription Required to Buy Etoricoxib Online?

This depends on the country. In nearly all places where etoricoxib is sold, it is a prescription-only medicine. It is not an FDA-approved product, so it should not be expected to be available through U.S. licensed pharmacies.

Who to Talk To

Depending on your condition, you may speak with:

• A rheumatologist for rheumatoid arthritis, ankylosing spondylitis, gout, and other inflammatory conditions
• An orthopedic specialist for osteoarthritis or joint and muscle injuries
• A dentist or oral surgeon for pain after dental procedures
• A primary care physician or pain management specialist for pain-related concerns
• A pharmacist for questions about interactions and how to take your medicine

Buying Safely Online

• Purchase only from licensed, accredited pharmacies in your own country that require a valid prescription.
• Be cautious of websites that sell etoricoxib without a prescription or ship it from unknown sources. Counterfeit, contaminated, or incorrectly dosed medicines are a real risk.
• Check that packaging is sealed, clearly labeled, and not expired.
• Avoid veterinary products. Animal medicines are not made or approved for human use.
• If you live in the United States, talk to your doctor about FDA-approved alternatives rather than importing medicines.

Side Effects of Etoricoxib

Many people take etoricoxib without serious problems. Side effects are more likely with higher doses and longer treatment.

Common Side Effects

• Upset stomach, heartburn, or indigestion
• Stomach pain
• Nausea
• Diarrhea
• Gas or bloating
• Headache
• Dizziness
• Weakness or tiredness
• Swelling in the hands, feet, or ankles
• Increased blood pressure
• Raised liver enzymes on blood tests (usually found by a doctor)
• Easy bruising

Contact your doctor if a common side effect does not go away or becomes bothersome.

Serious Side Effects

Serious side effects are uncommon but can be life-threatening. Stop taking etoricoxib and get medical help right away if you notice any of the following:

• Black, tarry, or bloody stools
• Vomiting blood or material that looks like coffee grounds
• Severe or persistent stomach pain
• Chest pain, shortness of breath, weakness on one side of the body, slurred speech, or sudden vision changes (possible signs of heart attack or stroke)
• Very high blood pressure, severe headache, or a pounding heartbeat
• Swelling of the face, lips, tongue, or throat, or trouble breathing (signs of a serious allergic reaction)
• Severe skin rash, blisters, peeling skin, mouth sores, or a rash with fever
• Sudden weight gain, severe swelling, or very little urine (possible kidney or heart problems)
• Yellowing of the skin or eyes, dark urine, or severe tiredness (possible liver problems)
• Unusual bruising or bleeding, or unusual paleness

If you think someone has taken too much etoricoxib, call your local poison control center or emergency number right away.

Drug Interactions

Etoricoxib can interact with many other medicines. Interactions may raise the risk of bleeding, kidney problems, or high blood pressure, or may change how well a medicine works.

Prescription Medications

• Other NSAIDs (such as ibuprofen, naproxen, diclofenac, celecoxib, or meloxicam): taking two NSAIDs together raises the risk of stomach bleeding and kidney injury.
• Aspirin: Using aspirin with etoricoxib increases the risk of stomach bleeding. Etoricoxib does not replace low-dose aspirin taken for heart protection, so do not stop aspirin unless your doctor tells you to.
• Blood thinners (such as warfarin, apixaban, rivaroxaban, or clopidogrel): bleeding risk increases. People taking warfarin usually need closer blood-clotting (INR) checks.
• Blood pressure medicines (ACE inhibitors, ARBs, beta-blockers, and diuretics): etoricoxib may reduce their effect and may raise the risk of kidney problems.
• Rifampicin (an antibiotic): can lower etoricoxib levels in the blood, which may make it work less well.
• Corticosteroids (such as prednisone): higher risk of stomach ulcers and bleeding.
• Antidepressants (SSRIs and SNRIs): higher risk of bleeding.
• Lithium: etoricoxib can raise lithium levels in the blood.
• Methotrexate: etoricoxib may increase methotrexate levels and the risk of toxicity.
• Cyclosporine and tacrolimus: higher risk of kidney damage.
• Birth control pills and hormone replacement therapy: etoricoxib may increase the level of estrogen in the blood. Tell your doctor if you use these.

Over-the-Counter Medications

• Pain relievers and cold, flu, or sinus products that contain ibuprofen, naproxen, diclofenac, or aspirin
• Some stomach remedies that contain salicylates

Supplements and Herbal Products

• Ginkgo biloba, high-dose fish oil, garlic supplements, ginger, and willow bark may increase bleeding risk
• Other herbal products may also interact, even when labeled “natural”

Alcohol

Drinking alcohol while taking etoricoxib can raise the risk of stomach irritation and bleeding.

Tip: Give your licensed medical specialist and pharmacist a complete list of everything you take, including prescriptions, OTC medicines, vitamins, supplements, and herbal products.

Safety & Important Considerations

Class Safety Warnings for NSAIDs

Health authorities around the world require warnings for NSAIDs, including etoricoxib, about:

• Heart and blood vessel risk: NSAIDs, and COX-2 inhibitors in particular, may raise the risk of heart attack and stroke. This risk may be higher with higher doses, longer use, or existing heart disease. Etoricoxib should not be used by people with established heart disease, stroke, or poorly controlled high blood pressure.
• Stomach and intestinal risk: NSAIDs can cause ulcers, bleeding, and tears in the stomach or intestines. These problems can occur without warning and are more likely in older adults and people with a history of ulcers or bleeding.
• Serious skin reactions and allergic reactions: These are rare but can happen early in treatment.

Blood Pressure

Etoricoxib can raise blood pressure, sometimes within the first weeks of use. Your blood pressure should be checked when you start treatment and at regular visits. Tell your doctor right away if it becomes high.

Kidney Disease

Etoricoxib can reduce blood flow to the kidneys and cause the body to hold on to fluid. People with kidney disease, dehydration, or heart failure, and those taking diuretics or blood pressure medicines, should use it only under medical guidance. It should not be used in people with severe kidney impairment.

Liver Disease

NSAIDs can rarely cause liver injury. People with liver disease should check with a doctor first. Etoricoxib should not be used in people with severe liver disease. Your doctor may order liver tests, especially with longer use.

Pregnancy and Breastfeeding

• Pregnancy: Etoricoxib should not be used during pregnancy. NSAIDs used at 20 weeks of pregnancy or later may cause rare but serious kidney problems in the unborn baby and low amniotic fluid. They may also make it harder for some women to become pregnant. Talk to your doctor if you are pregnant or planning to become pregnant.
• Breastfeeding: It is not known how much etoricoxib passes into breast milk, and it is generally advised not to use it while breastfeeding.

Children

Etoricoxib is not recommended for children and adolescents under 16 because safety and effectiveness have not been established.

Older Adults

Adults over 65 are at higher risk for stomach bleeding, kidney problems, and heart-related side effects. Lower doses and shorter treatment are often advised.

Monitoring

Depending on your health history and how long you take etoricoxib, your specialist may check:

• Blood pressure
• Kidney function and liver tests (blood tests)
• Blood counts, especially if you have signs of bleeding or anemia
• Symptoms such as stomach pain, swelling, or changes in urination

Other Precautions

• Etoricoxib may cause dizziness or tiredness. Use caution when driving or operating machinery until you know how it affects you.
• NSAIDs may hide signs of infection, such as fever and swelling. Seek medical care if symptoms worsen.
• Tell all of your health care providers, including your dentist, that you take etoricoxib before any surgery or procedure.

Who This Medication Is For

Etoricoxib is generally prescribed for:

• Adults with osteoarthritis, rheumatoid arthritis, or ankylosing spondylitis who need relief from pain, stiffness, and swelling
• Adults with an acute gout flare
• Adults who need short-term relief from pain after dental surgery or from other acute pain, depending on local approval

Etoricoxib is not right for everyone. A licensed medical specialist will decide whether it is a suitable choice based on your health history and other medicines.

Who Should Not Take Etoricoxib

Do not take etoricoxib if you:

• Have had an allergic reaction (such as hives, wheezing, or swelling) to etoricoxib, aspirin, or any other NSAID
• Have a history of asthma, nasal polyps, or breathing problems triggered by aspirin or NSAIDs
• Have an active stomach or intestinal ulcer or bleeding
• Have inflammatory bowel disease, such as Crohn’s disease or ulcerative colitis
• Have heart failure, established heart disease, stroke, or peripheral artery disease
• Have high blood pressure that is not well controlled
• Have severe kidney or liver impairment
• Are pregnant or breastfeeding
• Are under 16 years of age
• Are about to have or have recently had heart bypass surgery

Talk to your doctor before use if you:

• Have risk factors for heart disease, such as high cholesterol, diabetes, or smoking
• Have a history of stomach problems
• Have mild to moderate kidney or liver disease
• Have asthma or lupus
• Drink alcohol regularly
• Are over age 60

What to Do If You Miss a Dose

• If you miss a dose, take it as soon as you remember on the same day.
• If it is almost time for your next dose, or if you remember on the next day, skip the missed dose and return to your normal schedule.
• Never take a double dose to make up for a missed one.
• If you take etoricoxib only for a short-term condition, follow the instructions your doctor gave you.
• If you are unsure what to do, contact your licensed medical specialist or pharmacist.

Related medications to Etoricoxib

Other medicines may be used for similar conditions. Which one is appropriate depends on your health history, other medications, and the reason for treatment.

• Other COX-2 inhibitors: celecoxib
• Other NSAIDs: ibuprofen, naproxen, diclofenac, aceclofenac, meloxicam, and etodolac These work in a similar way but differ in strength, how long they last, and risk profile.
• Acetaminophen (paracetamol): A pain and fever reducer that is not an NSAID. It does not reduce inflammation, and it must be used carefully to avoid liver injury.
• Gout-specific medicines: For gout flares, doctors may also use colchicine or short courses of corticosteroids. Long-term gout treatment may use medicines that lower uric acid.
• Disease-modifying medicines: For rheumatoid arthritis or ankylosing spondylitis, specialists may use other medicines that treat the underlying disease rather than only the symptoms.
• Non-medication approaches: Physical therapy, exercise, heat or cold therapy, and weight management may help some people with joint pain.

Do not switch, combine, or stop medications without speaking to a licensed medical specialist. Switching treatments requires a full review of your health history and other medicines.

Storage Instructions

• Store at room temperature, generally below 86°F (30°C), unless the label says otherwise.
• Keep tablets in the original package and in a dry place away from moisture. Avoid storing in bathrooms.
• Protect from heat and direct light.
• Keep out of reach and sight of children and pets. Store medicines in a high, secure location.
