Indications and Contraindications of Indometacin

Indications

The American College of Rheumatology recommends indometacin as an effective NSAID for the treatment of active ankylosing spondylitis (AS), particularly for pain and stiffness, with a dosage of 75-150 mg/day divided into several doses 1, 2
The European League Against Rheumatism recommends indometacin for the treatment of acute gouty arthritis, with a dosage of 50 mg three times a day, until resolution of the acute attack 3, 4

For ankylosing spondylitis, the recommended dosage is 75-150 mg/day divided into several doses, with continuous treatment during active disease periods instead of on-demand treatment 1, 2
For acute gouty arthritis, the recommended initial dosage is 50 mg three times a day, until resolution of the acute attack 3

The American College of Rheumatology recommends avoiding indometacin in patients with a history of asthma, urticaria, or allergic reactions to aspirin or other NSAIDs, as well as in patients with active infection, high risk of infection, or malignancy 5
The European League Against Rheumatism recommends avoiding indometacin in patients with a history of lupus or multiple sclerosis, as well as in patients with chronic leg ulcers, previous tuberculosis, or septic arthritis 2, 5

The American Gastroenterological Association recommends considering the use of a gastroprotective agent or a selective COX-2 inhibitor in patients with increased gastrointestinal risk, as indometacin has a high potential for ulcerogenesis 4, 6
The European League Against Rheumatism recommends monitoring patients for common adverse effects, such as gastrointestinal symptoms, headache, hypertension, and depression, during prolonged treatment with indometacin 1

The American College of Rheumatology recommends choosing an NSAID based on the patient's history, risk factors, and comorbidities, rather than selecting a specific NSAID as a preferred option for ankylosing spondylitis 1, 2
The European League Against Rheumatism recommends using the lowest effective dose of indometacin for the shortest possible duration, and preferring continuous treatment over on-demand treatment during active disease periods 1, 2, 6

The American College of Physicians recommends an initial dose of 50 mg three times daily until pain becomes tolerable, with gastrointestinal adverse events occurring in 55% of patients at higher doses 7, 8

The Journal of the American Geriatrics Society recommends using indomethacin with greater care in elderly patients, with absolute contraindications including active peptic ulcer disease, chronic kidney disease, and heart failure 9
The World Journal of Emergency Surgery suggests using indomethacin with extreme caution in patients with renal impairment due to the risk of acute kidney injury 10

The American College of Rheumatology and the Journal of the American Geriatrics Society recommend routinely assessing for gastrointestinal toxicity, renal toxicity, hypertension, and heart failure, with particular attention needed in patients on ACE inhibitors, diuretics, or antiplatelets due to drug interactions 9, 10
Gastrointestinal adverse events were significantly more common with indomethacin (63%) compared to prednisolone (27%) in acute gout trials, highlighting the need for gastroprotective agents 7, 9
