Etoricoxib: Uses, Side Effects & Safety

What it is and what it's used for

Etoricoxib is a non-steroidal anti-inflammatory drug (NSAID) of the COX-2 selective type — a medicine that reduces pain and swelling. It is used for pain and inflammation linked to osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis, as well as for acute gouty arthritis (sudden gout attacks) and short-term pain such as dental pain, pain after surgery, and period pain.

In India, etoricoxib is a prescription medicine (Schedule H). It should only be taken on a doctor's advice, and it is generally meant for short-term use or for the shortest period needed, unless your doctor has specifically advised otherwise. It is not recommended for children and adolescents under 16 years of age.

How it works (simple language)

Pain and swelling in the body are partly driven by chemicals called prostaglandins, which are made at the site of injury or inflammation. Etoricoxib is thought to work by selectively blocking an enzyme called COX-2, which produces many of these chemicals, while largely sparing a related enzyme that helps protect the stomach lining. This lowers inflammation and eases pain. It treats the symptoms — it does not cure the underlying condition causing the pain.

Dosage forms available in India (general info only)

Etoricoxib is commonly available in India as 60 mg, 90 mg, and 120 mg film-coated tablets. Well-known Indian brand names include Nucoxia and Etoshine, though brands vary.

Never decide the dose yourself from this article. Always follow your doctor's prescription or the directions on the pack, and check with your pharmacist if you are unsure — especially for children, where the dose depends on the child's weight and age.

Side effects

Common: Headache, dizziness, stomach pain, acidity or heartburn, nausea, diarrhoea, swelling of the legs or ankles, tiredness, and raised blood pressure.

Serious — seek medical care: Vomiting blood or black, tarry stools (signs of stomach bleeding), severe stomach pain, swelling of the face, lips or tongue, difficulty breathing or wheezing, skin rash or peeling, yellowing of the skin or eyes, very little or no urine, chest pain, sudden weakness or slurred speech, or severe leg swelling. Stop the medicine and seek urgent medical help if any of these occur.

Precautions and warnings

• Do not take if you have heart disease: Etoricoxib can increase the risk of heart attack and stroke, and it must not be used by people with ischaemic heart disease, heart failure, peripheral arterial disease, or a history of stroke.
• Uncontrolled high blood pressure: Do not use etoricoxib if your blood pressure is not well controlled, and have your blood pressure checked regularly while taking it.
• Stomach ulcers or bleeding: Tell your doctor if you have had stomach ulcers or bleeding, as etoricoxib can still irritate the stomach and, rarely, cause bleeding.
• Kidney or liver disease: Etoricoxib can worsen kidney or liver problems, especially with long-term use, in older adults, or in people who are dehydrated.
• Asthma or allergy to painkillers: People who are allergic to aspirin or other NSAIDs, or who have asthma, may react badly to etoricoxib.
• Avoid alcohol and other painkillers: Drinking alcohol raises the risk of stomach bleeding and dizziness, and combining etoricoxib with other NSAIDs increases side-effect risk without extra benefit.
• Use the lowest dose for the shortest time: The risk of heart and stomach side effects rises with higher doses and longer use, so follow your doctor's instructions exactly and do not extend treatment on your own.

Interactions (general)

Etoricoxib can interact with blood thinners (such as warfarin), blood pressure medicines (ACE inhibitors, ARBs, and water pills/diuretics), methotrexate, lithium, ciclosporin, and some diabetes medicines. Taking it with steroids or other NSAIDs raises the risk of stomach bleeding. Alcohol should be avoided. Always tell your doctor about ALL medicines you take, including herbal and ayurvedic products, before starting etoricoxib.

Pregnancy and breastfeeding (general guidance)

Etoricoxib should be avoided during pregnancy, especially in the last three months, as it may harm the unborn baby and affect labour. It is generally not recommended while breastfeeding either, as it is not known whether it passes into breast milk in harmful amounts. Always consult your doctor first if you are pregnant, planning pregnancy, or breastfeeding.

Storage

Store etoricoxib tablets at room temperature, away from heat and moisture, and out of the reach of children. Do not use tablets past their expiry date, and do not share your medicine with others even if their symptoms seem similar.

When to see a doctor

See a doctor if: your pain does not improve or gets worse, you develop stomach pain, black stools, vomiting blood, swelling, rash, or breathing difficulty, or you need painkillers for more than a few days. Seek emergency care immediately for signs of stomach bleeding, severe allergic reaction, chest pain, sudden weakness or slurred speech, or signs of a stroke.

FAQs

1. What is etoricoxib used for?

Etoricoxib is used to relieve pain and inflammation in conditions such as osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis, and for short-term pain including acute gout attacks, dental pain, and period pain. It treats symptoms and does not cure the underlying disease.

2. Is etoricoxib stronger than other painkillers?

Etoricoxib belongs to a selective group of anti-inflammatory medicines and is often used when other painkillers have not helped enough, but "stronger" does not mean safer — it carries its own heart, stomach, and kidney risks. Your doctor chooses the medicine and dose based on your condition and health history.

3. Can I take etoricoxib every day for a long time?

Only if your doctor has advised it. Etoricoxib is usually used for the shortest period needed at the lowest effective dose, because long-term use raises the risk of heart, stomach, and kidney side effects. Never continue it on your own without medical review.

4. Who should not take etoricoxib?

People with heart disease, heart failure, uncontrolled high blood pressure, a history of stroke, active stomach ulcers or bleeding, or severe kidney or liver disease should not take etoricoxib. It is also not recommended in late pregnancy or for children under 16. Always tell your doctor about your full health history before starting it.
