Etoricoxib 90 Mg – Pain Relief Uses & Side Effects

Aug 18, 2026

What Is Etoricoxib 90 mg Tablet?

Etoricoxib 90 mg tablet contains etoricoxib 90 mg, an anti-inflammatory medicine designed to selectively inhibit the COX-2 enzyme. COX-2 is involved in the production of prostaglandins, chemical messengers associated with pain and inflammation.

By reducing COX-2 activity, etoricoxib can help decrease pain, swelling, tenderness, and inflammation. Unlike traditional non-selective NSAIDs, selective COX-2 inhibitors preferentially target COX-2; however, this does not mean etoricoxib is risk-free. Cardiovascular, blood-pressure, kidney, liver, and gastrointestinal considerations remain important. 

Etoricoxib 90 mg Tablet Uses

The primary etoricoxib 90 mg tablet uses are related to the relief of pain and inflammation.

Doctors may prescribe etoricoxib for:

  • Rheumatoid arthritis: Helps relieve joint pain, tenderness, and inflammation.
  • Ankylosing spondylitis: May reduce inflammatory pain and stiffness.
  • Osteoarthritis: Can help manage pain and improve day-to-day movement.
  • Acute gouty arthritis: Helps relieve the intense pain and inflammation associated with an acute gout attack.
  • Certain short-term moderate pain: Etoricoxib may be prescribed for short-term pain following dental surgery in appropriate patients.

The exact indication, dose, and duration depend on the patient's condition and medical history. Etoricoxib is not intended to cure the underlying cause of arthritis or gout; it primarily provides symptomatic relief.

Key Benefits of Etoricoxib 90 mg Tablet

1. Helps relieve pain

One of the major benefits of etoricoxib 90 mg is its ability to reduce inflammatory pain. It may help people perform routine activities more comfortably when pain is limiting movement.

2. Reduces inflammation and swelling

Etoricoxib decreases COX-2-mediated prostaglandin production, helping reduce inflammation associated with several musculoskeletal and joint conditions.

3. Can improve mobility

When joint pain and inflammation are reduced, some patients may find it easier to move affected joints and perform everyday activities.

4. Useful for inflammatory joint conditions

Etoricoxib is used in conditions such as rheumatoid arthritis and ankylosing spondylitis where inflammation contributes significantly to pain and stiffness. 

5. Once-daily dosing for many indications

Etoricoxib is commonly administered once daily for several approved indications, although the appropriate dose depends on the condition being treated. Patients should follow their individual prescription rather than selecting a dose themselves.

How Does Etoricoxib 90 mg Work?

Etoricoxib works mainly by selectively blocking the cyclooxygenase-2 (COX-2) enzyme. COX-2 contributes to the production of prostaglandins involved in inflammation and pain.

When COX-2 activity is reduced, fewer inflammatory chemical signals are produced. This can result in decreased pain, swelling, and inflammation.

Because etoricoxib affects inflammatory pathways rather than eliminating the underlying disease, symptom relief does not necessarily mean the underlying condition has been cured.

How to Take Etoricoxib 90 mg Tablet

Take etoricoxib 90 mg tablet exactly as prescribed by your doctor. It can generally be taken with or without food. Swallow the tablet with water and avoid taking a higher dose or using it for longer than recommended. Current Indian product information similarly advises taking etoricoxib according to the prescribed dose and duration. 

Using the lowest effective dose for the shortest appropriate duration is an important safety principle, particularly because cardiovascular and other risks can increase with higher doses or prolonged treatment.

Do not take an additional tablet if you miss a dose without first checking the instructions provided by your healthcare professional.

Etoricoxib 90 mg Tablet Side Effects

Like other NSAIDs, etoricoxib 90 mg tablet may cause side effects. Some are mild and temporary, while others require medical attention.

Possible side effects include:

  • Stomach pain or discomfort
  • Nausea or vomiting
  • Diarrhea
  • Headache
  • Dizziness
  • Swelling or fluid retention
  • Increased blood pressure
  • Increased liver enzymes
  • Changes in kidney function
  • Palpitations or irregular heartbeat in some patients 

Seek urgent medical attention if you develop symptoms that could indicate a serious reaction, such as chest pain, severe breathing difficulty, significant swelling, black or bloody stools, severe allergic symptoms, or other unusual or rapidly worsening symptoms.

Important Etoricoxib 90 mg Safety Precautions

Etoricoxib is not suitable for everyone. People with certain cardiovascular conditions, uncontrolled high blood pressure, serious kidney or liver disease, active stomach or intestinal ulcers or bleeding, or previous certain cardiovascular events may need to avoid it. The European Medicines Agency's product information specifically lists conditions including heart attack, stroke, peripheral arterial disease, certain heart failure, serious kidney or liver disease, and uncontrolled hypertension among contraindications or important precautions. 

Tell your doctor if you have:

  • High blood pressure
  • Heart disease
  • Previous heart attack or stroke
  • Kidney or liver problems
  • Stomach ulcers or gastrointestinal bleeding
  • Fluid retention or swelling
  • Asthma or previous reactions to NSAIDs
  • Diabetes or high cholesterol
  • A history of cardiovascular risk factors

Etoricoxib can increase blood pressure in some patients, so blood-pressure monitoring may be appropriate during treatment. 

Pregnant or breastfeeding patients should discuss etoricoxib use with their healthcare professional before taking it. It should also not be combined with other medicines without checking for potential interactions.

Who Should Avoid Self-Medicating With Etoricoxib?

Etoricoxib should not be selected simply because you have pain. Different causes of pain require different treatments.

In particular, people with a history of cardiovascular disease, uncontrolled hypertension, significant kidney or liver disease, gastrointestinal bleeding, or NSAID allergy should speak with a doctor before using it. Etoricoxib has recognized cardiovascular risks, and regulators have emphasized that these risks should be considered when determining whether treatment is appropriate.
