Indometacin
Indometacin, sold as Indocin, is a nonsteroidal anti-inflammatory drug in the Pain & Anti-inflammatories range, used to ease joint pain and swelling in arthritis. This shelf carries one product: Indocin capsules in 25 mg, 50 mg and 75 mg strengths.
Key points
- Indometacin is listed for osteoarthritis, rheumatoid arthritis, ankylosing spondylitis and gouty arthritis.
- Indocin is the brand-name version of indometacin, a Merck product.
- NSAIDs including indometacin carry a boxed warning for increased risk of heart attack, stroke, and serious stomach bleeding or ulcers.
How does Indometacin work?
Indometacin blocks both COX-1 and COX-2 enzymes, the body’s main producers of prostaglandins. Prostaglandins drive pain, fever and swelling, so reducing them eases joint symptoms. Because the drug is nonselective, it also inhibits COX-1 in the stomach lining, which is why indometacin can irritate the gut.
