1. What Is Celecoxib and What Is It Used For?
Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) classified as a COX-2 inhibitor. It’s primarily used to alleviate pain, reduce inflammation, and manage various conditions associated with arthritis and other painful ailments. Celecoxib offers relief by targeting specific enzymes in the body that contribute to pain and inflammation.

2. How Does Celecoxib Work in the Body?
Celecoxib works by selectively inhibiting cyclooxygenase-2 (COX-2), an enzyme responsible for producing prostaglandins, which are substances that cause pain and inflammation. Unlike traditional NSAIDs, celecoxib has a lower affinity for COX-1, an enzyme that protects the stomach lining. This selectivity may result in a reduced risk of gastrointestinal side effects compared to non-selective NSAIDs.
3. What Conditions Does Celecoxib Treat?
Celecoxib is prescribed for a range of conditions, including:
- Osteoarthritis: Eases pain, tenderness, swelling, and stiffness caused by the breakdown of joint lining.
- Rheumatoid Arthritis: Reduces inflammation and pain associated with swelling of the joint linings.
- Ankylosing Spondylitis: Manages arthritis primarily affecting the spine, alleviating pain and stiffness.
- Juvenile Rheumatoid Arthritis: Treats arthritis in children aged 2 years and older.
- Painful Menstrual Periods: Relieves pain associated with menstruation.
- Short-Term Pain: Manages pain caused by injuries, surgeries, or other medical and dental procedures.
- Familial Adenomatous Polyposis: Used with surgery to reduce the number of polyps in the colon and rectum.
4. What Is the Recommended Dosage for Celecoxib?
The dosage of celecoxib varies depending on the condition being treated and individual patient factors. Here are general guidelines:
- Osteoarthritis: 200 mg once daily or 100 mg twice daily.
- Rheumatoid Arthritis: 100 to 200 mg twice daily.
- Ankylosing Spondylitis: 200 mg once daily or 100 mg twice daily. If no effect is observed after 6 weeks, a trial of 400 mg once daily or 200 mg twice daily may be worthwhile.
- Juvenile Rheumatoid Arthritis (2 years and older): Dosage is based on weight.
- Acute Pain and Primary Dysmenorrhea: 400 mg initially, followed by an additional 200 mg dose if needed on the first day. On subsequent days, the recommended dose is 200 mg twice daily as needed.
It is crucial to follow your doctor’s specific instructions and not exceed the prescribed dosage.
5. How Should Celecoxib Be Taken for Best Results?
To maximize the effectiveness of celecoxib:
- Follow Directions: Take celecoxib exactly as prescribed by your doctor.
