Celecoxib (Celebrex): Uses, Side Effects, Warnings, Precautions, and Patient Information

What Is Celecoxib (Celebrex)?

Celecoxib is a prescription nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, inflammation, and stiffness caused by various conditions, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute pain, primary dysmenorrhea (menstrual cramps), and juvenile idiopathic arthritis in certain pediatric patients.

Celecoxib belongs to a group of medicines called selective cyclooxygenase-2 (COX-2) inhibitors. Unlike many traditional NSAIDs, celecoxib selectively blocks the COX-2 enzyme, helping reduce pain and inflammation while generally causing less stomach irritation than non-selective NSAIDs. However, it still carries important risks, including serious cardiovascular and gastrointestinal side effects.

How Celecoxib Works

Celecoxib selectively blocks the cyclooxygenase-2 (COX-2) enzyme responsible for producing prostaglandins that cause pain, inflammation, and fever. By reducing prostaglandin production, celecoxib helps relieve pain, decrease inflammation, and improve joint function while having less effect on the COX-1 enzyme that helps protect the stomach lining.
