Indometacin for Pain and Inflammation (Indocid)

Indometacin is a non-steroidal anti-inflammatory drug (NSAID) prescribed to reduce

pain

and

inflammation

. It is particularly effective for acute conditions such as gout attacks and short-term musculoskeletal injuries.

About indometacin tablets

Indometacin tablets contain 25mg or 50mg of the active ingredient indometacin, which belongs to the NSAID class of medicines. These drugs work by blocking the production of prostaglandins—chemicals in the body that cause pain, fever, and inflammation. By inhibiting enzymes called cyclooxygenase (COX-1 and COX-2), indometacin provides relief from moderate to severe pain associated with inflammatory conditions.

Available under brand names like

Indocid

, indometacin is typically taken orally in capsule or tablet form. It is absorbed quickly from the gastrointestinal tract, with peak blood levels reached within 2 hours. Common forms include immediate-release capsules for fast action and sustained-release versions for longer-lasting effects.

In the UK, indometacin requires a prescription and is not suitable for everyone due to potential risks, especially gastrointestinal bleeding and cardiovascular events. It is often chosen when other painkillers like paracetamol or ibuprofen are insufficient.

• Dosage forms: 25mg and 50mg capsules/tablets; suppositories also available for rectal use.
• Starting dose: Usually 25mg 2–3 times daily, increased if needed.

What is indometacin used for?

Indometacin is prescribed for a variety of painful and inflammatory conditions where standard painkillers fail. It excels in treating acute episodes rather than chronic daily use.

Types of pain and inflammation treated by indometacin

• Rheumatoid arthritis and osteoarthritis: Reduces joint pain, swelling, and stiffness in moderate to severe cases.
• Ankylosing spondylitis: Eases back pain and improves mobility in this spinal arthritis.
• Gout attacks: Quickly relieves severe pain and inflammation from uric acid crystal buildup in joints.
• Musculoskeletal injuries: Sprains, strains, tendonitis, bursitis, and frozen shoulder.
• Post-operative pain: After certain surgeries, excluding heart bypass (CABG).
• Other uses: Pericarditis, dysmenorrhoea (painful periods), and migraine prophylaxis in some cases.

Indometacin is not first-line for mild pain; paracetamol or weaker NSAIDs are preferred initially.
