Celecoxib

What is Celecoxib?

Celecoxib is a prescription non-steroidal anti-inflammatory drug (NSAID) that selectively inhibits the cyclooxygenase-2 (COX-2) enzyme, which is responsible for producing prostaglandins that cause pain and inflammation. It is approved by the European Medicines Agency (EMA) for the treatment of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute pain in adults.

How does Celecoxib work?

Unlike traditional NSAIDs that inhibit both COX-1 and COX-2 enzymes, Celecoxib selectively targets only COX-2. This distinction is clinically significant:

• Targeted anti-inflammatory action: By blocking COX-2, Celecoxib reduces the production of prostaglandins at sites of inflammation, thereby decreasing pain, swelling, and stiffness.
• Preserved gastric protection: COX-1 plays a protective role in maintaining the stomach lining. Because Celecoxib largely spares COX-1, it is associated with a lower incidence of gastrointestinal ulcers compared to non-selective NSAIDs.
• Fever reduction: Celecoxib also inhibits the prostaglandins responsible for fever, providing antipyretic effects.
• No antiplatelet effect: Unlike aspirin and non-selective NSAIDs, Celecoxib does not significantly inhibit platelet aggregation at therapeutic doses, which is relevant for patients on anticoagulation therapy.

The onset of analgesic effect typically occurs within one to two hours of taking the first dose, with anti-inflammatory benefits developing over several days of regular use.

Who is Celecoxib for?

Celecoxib is indicated for adults experiencing pain and inflammation associated with:

• Osteoarthritis: Joint degeneration causing pain and stiffness, most commonly in the knees, hips, and hands.
• Rheumatoid arthritis: An autoimmune condition causing chronic joint inflammation.
• Ankylosing spondylitis: Inflammatory arthritis primarily affecting the spine and sacroiliac joints.
• Acute pain: Post-operative or injury-related pain in adults.

Celecoxib is particularly considered for patients who require NSAID therapy but have a history of gastrointestinal intolerance to non-selective NSAIDs. It is not appropriate for patients with significant cardiovascular disease, severe heart failure, known sulfonamide hypersensitivity, or severe hepatic impairment. A full medical assessment is required before any prescription is issued.

Dosage

Celecoxib is taken orally as capsules. The recommended dosing schedule, per EMA-approved prescribing guidance, varies by indication:

Indication	Recommended Dose	Maximum Daily Dose
Osteoarthritis	200 mg once daily or 100 mg twice daily	200 mg/day
Rheumatoid arthritis	100–200 mg twice daily	400 mg/day
Ankylosing spondylitis	200 mg once daily or 100 mg twice daily	400 mg/day
Acute pain	400 mg initially, then 200 mg if needed	400 mg on day 1

Celecoxib should be taken at the lowest effective dose for the shortest duration necessary to control symptoms. It can be taken with or without food. Patients should not exceed the recommended dose without guidance from their prescribing doctor.

Side effects

As with all medicines, Celecoxib may cause side effects. Not everyone experiences them, and many are mild and transient.

Common side effects (may affect up to 1 in 10 people)

• Headache
• Dizziness
• Diarrhoea
• Indigestion (dyspepsia)
• Abdominal pain
• Upper respiratory tract infections
• Peripheral oedema (swelling of the ankles or feet)

Less common but serious side effects

• Cardiovascular events: NSAIDs, including COX-2 selective inhibitors, are associated with a small increased risk of heart attack and stroke with prolonged use, particularly at higher doses. Patients with established cardiovascular disease or risk factors should discuss this with their doctor.
• Serious gastrointestinal events: Although less common than with non-selective NSAIDs, ulcers, perforation, and gastrointestinal bleeding can still occur. Seek medical attention for any signs of GI bleeding, including dark or tarry stools.
• Hepatic reactions: Rare cases of serious liver reactions have been reported. Report any signs of jaundice or abnormal liver function promptly.
• Severe allergic reactions: Including anaphylaxis. Patients with a known sulfonamide allergy are at increased risk and should not take Celecoxib.
• Renal impairment: NSAIDs can reduce renal blood flow and precipitate acute kidney injury, particularly in elderly patients or those with pre-existing kidney disease.

How to get Celecoxib online in Europe

Celecoxib is a prescription-only medicine (POM) across all EU member states and cannot be legally dispensed without a valid prescription from a licensed medical professional.

Prescrivia operates as a technology intermediary platform: we do not prescribe medicines, employ doctors, or sell medicines. Our platform connects patients with independent EU-registered doctors who can conduct confidential online health assessments.

The process works as follows:

1. Complete a health assessment: Answer a structured set of health questions covering your medical history, current medications, and pain management needs. This information is reviewed by an independent doctor.
2. Doctor review: An independent EU-registered doctor reviews your assessment. If Celecoxib is clinically appropriate for your circumstances, they may issue a prescription. If it is not appropriate, the doctor will advise accordingly.
3. Prescription and fulfilment: If a prescription is issued, it is forwarded to a licensed EU pharmacy partner, which dispenses and ships the medicine directly to you.

Important: Prescrivia does not guarantee that a prescription will be issued. All prescribing decisions are made independently by qualified medical professionals based on your individual clinical circumstances.

Important safety information

Do not use Celecoxib if you:

• Have a known allergy to sulfonamides or any ingredient in Celecoxib
• Have experienced asthma, urticaria, or allergic reactions after taking aspirin or other NSAIDs
• Have active peptic ulcer disease or gastrointestinal bleeding
• Have severe heart failure, severe hepatic impairment, or severe renal impairment
• Are in the third trimester of pregnancy or breastfeeding

Tell your doctor before starting Celecoxib if you have:

• A history of cardiovascular disease, high blood pressure, or elevated cholesterol
• A history of gastrointestinal ulcers or bleeding
• Kidney or liver disease
• Fluid retention or heart failure
• A history of asthma

Drug interactions: Celecoxib may interact with warfarin and other anticoagulants, ACE inhibitors, diuretics, lithium, and certain antifungal medications (fluconazole increases Celecoxib plasma levels significantly). Always disclose all current medications to your doctor during the assessment.

Celecoxib is not appropriate for long-term use without regular medical review. The lowest effective dose should be used for the shortest possible duration.
