Generic Celecoxib Information

Introduction

Celecoxib is a non‑steroidal anti‑inflammatory drug (NSAID) classified as a selective cyclo‑oxygenase‑2 (COX‑2) inhibitor. It is used primarily for pain relief and inflammation control in a range of musculoskeletal and rheumatologic conditions. In Hong Kong, Celecoxib is prescribed by physicians and dispensed by licensed pharmacies, and it is also available through our online pharmacy as a regulated generic alternative. The active compound is Celecoxib, and the medication belongs to the Pain Relief group. Secondary uses include management of acute gout flares and postoperative pain when indicated.

What is Celecoxib?

Celecoxib is the generic version of Celebrex®, the original brand developed by Pfizer. Both contain the same active compound, Celecoxib, and provide equivalent therapeutic effects when manufactured according to Good Manufacturing Practice standards. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, sourced from verified international suppliers that meet Hong Kong’s pharmaceutical quality requirements.

Celecoxib belongs to the class of selective COX‑2 inhibitors, a subgroup of NSAIDs designed to reduce gastrointestinal toxicity while maintaining anti‑inflammatory potency. It was first approved by the U.S. Food and Drug Administration (FDA) in 1999 and is now marketed worldwide under numerous generic labels.

How Celecoxib Works

Celecoxib selectively blocks the cyclo‑oxygenase‑2 enzyme, which catalyzes the conversion of arachidonic acid to prostaglandins that mediate pain, fever, and inflammation. By inhibiting COX‑2 while sparing COX‑1 (which protects gastric mucosa and supports platelet function), Celecoxib reduces the production of inflammatory prostaglandins at sites of injury without the full gastrointestinal side‑effect profile typical of non‑selective NSAIDs.

• Onset of action: Analgesic effect usually begins within 1–2 hours after oral ingestion.
• Duration: Therapeutic plasma concentrations are maintained for approximately 12 hours, supporting once‑ or twice‑daily dosing.
• Metabolism and clearance: Hepatic metabolism occurs mainly via CYP2C9; the drug’s half‑life is approximately 11 hours, allowing steady‑state concentrations after 2–3 days of regular dosing.

Conditions Treated with Celecoxib

• Osteoarthritis – Reduces joint pain and stiffness, improving functional mobility. In Hong Kong, osteoarthritis prevalence rises sharply after age 60, affecting up to 20 % of the elderly population.
• Rheumatoid arthritis – Controls synovial inflammation and limits structural joint damage when combined with disease‑modifying antirheumatic drugs (DMARDs).
• Ankylosing spondylitis – Alleviates axial skeleton pain and improves spinal flexibility.
• Acute musculoskeletal pain – Effective for sprains, strains, and postoperative pain when NSAID therapy is appropriate.
• Acute gout flares – Provides rapid anti‑inflammatory relief where colchicine or corticosteroids are contraindicated.
• Primary dysmenorrhea – Occasionally prescribed for menstrual pain unresponsive to conventional NSAIDs.

Each indication benefits from Celecoxib’s ability to diminish prostaglandin‑mediated inflammation while offering a lower risk of gastroduodenal ulceration compared with traditional NSAIDs.

Patient Groups Most Likely to Benefit

• Adults with chronic osteoarthritis or rheumatoid arthritis who require long‑term pain control but have a history of gastrointestinal irritation from non‑selective NSAIDs.
• Patients undergoing orthopedic surgery who need short‑term postoperative analgesia.
• Individuals with high cardiovascular risk should use Celecoxib only when the benefit outweighs potential risk; low‑dose regimens may be appropriate under close monitoring.
• Patients with aspirin‑sensitive asthma may experience bronchospasm with COX‑2 inhibition and should be evaluated before initiating therapy.

Celecoxib is generally not appropriate for:

• Children and adolescents under 18 years for most indications (except juvenile idiopathic arthritis under specialist supervision).
• patients with severe hepatic impairment, end‑stage renal disease, or known hypersensitivity to sulfonamides.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal discomfort (abdominal pain, dyspepsia)
• Headache or dizziness
• Elevated blood pressure
• Peripheral edema

Rare

• Mild liver enzyme elevation (ALT, AST)
• Skin rash, pruritus
• Mild renal function changes (increase in serum creatinine)

Serious

• Cardiovascular events (myocardial infarction, stroke) – incidence higher in patients with existing cardiovascular disease or prolonged high‑dose use.
• Severe hypersensitivity reactions (anaphylaxis, Stevens‑Johnson syndrome).
• Gastrointestinal perforation or ulceration, though less common than with non‑selective NSAIDs.
• Thromboembolic complications (deep‑vein thrombosis, pulmonary embolism).

Drug–Drug Interactions

• Anticoagulants (warfarin, direct oral anticoagulants) – additive bleeding risk.
• Dual antiplatelet agents (aspirin, clopidogrel) – heightened hemorrhagic potential.
• Selective serotonin reuptake inhibitors (SSRIs) – increased gastrointestinal bleeding risk.
• ACE inhibitors / ARBs – may reduce antihypertensive efficacy and worsen renal function when combined.
• Lithium – Celecoxib can raise serum lithium levels; monitor closely.
• Cytochrome P450 2C9 inhibitors (e.g., fluconazole) – may increase Celecoxib plasma concentrations, raising toxicity risk.

Patients should disclose all concurrent medications—including over‑the‑counter products and herbal supplements—to their healthcare provider before initiating Celecoxib.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing

  • Osteoarthritis / rheumatoid arthritis: 200 mg once daily or 100 mg twice daily.
  • Ankylosing spondylitis: 200 mg twice daily.
  • Acute pain or gout flare: 400 mg loading dose, then 200 mg after 12 hours, followed by 200 mg twice daily as needed (maximum 400 mg per day).

• Administration

  • Take with food or a full glass of water to minimize gastric irritation.
  • Do not exceed the prescribed daily maximum; higher doses increase cardiovascular risk.

• Missed dose

  • If a dose is missed and the scheduled time is ≥ 12 hours away, take the missed dose.
  • If it is sooner, skip the missed dose and resume the regular schedule. Do not double‑dose.

• Overdose

  • Symptoms may include nausea, vomiting, abdominal pain, dizziness, and possible renal impairment.
  • Seek immediate medical attention; supportive care and gastric decontamination may be required.

• Precautions

  • Avoid concurrent alcohol consumption, which can exacerbate gastric irritation.
  • Monitor blood pressure regularly, especially in patients with hypertension.
  • Use the lowest effective dose for the shortest duration compatible with clinical goals.

FAQ

• Is Celecoxib covered by the Hong Kong Hospital Authority’s drug formulary?
  Yes, Celecoxib is listed on the Hospital Authority’s formulary for specific rheumatologic indications, but coverage depends on individual patient eligibility and physician recommendation. Patients should verify reimbursement status with their public or private health insurer.

• Can Celecoxib be taken on an empty stomach?
  While Celecoxib’s COX‑2 selectivity reduces direct gastric irritation, taking it with food or milk is still advised to further lower the risk of dyspepsia and to improve tolerability, especially for long‑term users.

• What is the difference between Celebrex® and generic Celecoxib?
  Celebrex® is the original brand product manufactured by Pfizer. Generic Celecoxib contains the identical active ingredient, same dosage strength, and must meet the same regulatory standards for safety, efficacy, and bioequivalence. The main difference lies in price, with generics typically being less expensive.

• Are there any special storage requirements for Celecoxib tablets?
  Store tablets at room temperature (15 °C–30 °C), protected from moisture, direct sunlight, and heat sources. Do not refrigerate; excessive humidity can degrade the tablet coating and reduce potency over time.

• How long does it take for Celecoxib to provide pain relief?
  Analgesic effects usually begin within 1–2 hours after oral administration, reaching peak plasma concentrations around 3 hours. Full anti‑inflammatory benefit may require several days of consistent dosing.

• Can Celecoxib be used safely during pregnancy or breastfeeding?
  Celecoxib is classified as Pregnancy Category C (risk cannot be ruled out). It should be avoided unless the potential benefit justifies the potential risk to the fetus. Excretion in breast milk is low, but caution is still recommended; alternatives are preferred for nursing mothers.

• What should I do if I develop a rash while taking Celecoxib?
  Discontinue the medication immediately and seek medical attention. A rash may signify an allergic reaction, which can progress to serious conditions such as Stevens‑Johnson syndrome. Prompt evaluation is essential.

• Does Celecoxib interact with traditional Chinese herbal medicines commonly used in Hong Kong?
  Certain herbs, such as Ginkgo biloba or St. John’s wort, can affect platelet function or CYP450 enzymes, potentially altering Celecoxib’s efficacy or safety profile. Discuss all herbal supplements with your clinician before starting therapy.

• How can I obtain a prescription for Celecoxib in Hong Kong?
