Indomethacin Contraindications

Indomethacin Contraindications is a non-steroidal anti-inflammatory agent (NSAID) that inhibits the enzyme cyclooxygenase necessary for the formation of prostaglandins and other autacoids. It also inhibits the motility of polymorphonuclear leukocytes.

Indomethacin is a Nonsteroidal Anti-inflammatory Drug. The mechanism of action of indomethacin is as a Cyclooxygenase Inhibitor. The chemical classification of indomethacin is Nonsteroidal Anti-inflammatory Compounds.

Indomethacin is used to treat moderate to severe osteoarthritis, rheumatoid arthritis, gouty arthritis, or ankylosing spondylitis. Indomethacin is also used to treat shoulder pain caused by bursitis or tendinitis.

Indomethacin Indications

Indomethacin Tablet is used for the treatment, control, prevention, & improvement of the following diseases, conditions, and symptoms

Therapeutic Indications Indomethacin

  • Anti-Inflammatory Agents, Non-Steroidal; Cardiovascular Agents; Cyclooxygenase Inhibitors; Gout Suppressants; Tocolytic Agents
  • Carefully consider the potential benefits and risks of indomethacin capsules and other treatment options before deciding to use indomethacin. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.
  • Indomethacin has been found effective in active stages of the following: Moderate to severe rheumatoid arthritis including acute flares of chronic disease. Moderate to severe ankylosing spondylitis. Moderate to severe osteoarthritis. Acute painful shoulder (bursitis and/or tendinitis).
  • Indomethacin for Injection is indicated to close a hemodynamically significant patent ductus arteriosus in premature infants weighing between 500 and 1,750 g when 48 hours usual medical management (e.g., fluid restriction, diuretics, digitalis, respiratory support, etc.) is ineffective. Clear-cut clinical evidence of a hemodynamically significant patent ductus arteriosus should be present, such as respiratory distress, a continuous murmur, a hyperactive precordium, cardiomegaly, or pulmonary plethora on chest x-ray.
  • IV indomethacin sodium trihydrate has been used prophylactically in premature neonates with subclinical patent ductus arteriosus (PDA) and as routine prophylaxis during the first day of life in low-birthweight premature neonates.
  • In the management of Reiter’s syndrome, many clinicians consider indomethacin a drug of choice.
  • Indomethacin also has been used to reduce the pain, fever, and inflammation of pleurisy and pleuritic chest pain of diverse origins.
  • Indomethacin has been used to inhibit uterine contractions during preterm labor (tocolysis) and thus prolong gestation. However, safety and efficacy of indomethacin for tocolysis have not been established and such use is controversial since there have been reports of serious adverse fetal effects, including constriction of the fetal ductus arteriosus, neonatal primary pulmonary hypertension, and fetal deaths.
  • A 1% indomethacin suspension has been applied topically to the eye for the prevention of postoperative cystoid macular edema in patients undergoing cataract surgery or retinal surgery, but a commercially available ophthalmic preparation currently is not available in the US.
  • Indomethacin has been recommended by some clinicians to treat orthostatic hypotension associated with multiple system atrophy characterized by predominantly autonomic failure (formerly known as Shy-Drager syndrome). It has been suggested, however, that at least some autonomic activity must be present for indomethacin therapy to be successful in this condition.
  • Indomethacin has also been used for symptomatic treatment of postoperative pain, biliary pain, chronic erythema nodosum, and certain types of a headache (e.g., cluster headache, exertional headache).
  • Although indomethacin has been used in the treatment of primary pulmonary hypertension, it appears that the drug provides little hemodynamic benefit in these patients and may adversely affect their hemodynamic status.
  • Indomethacin has been used for its antipyretic effect in the management of fever associated with infection in children and with neoplasms (e.g., Hodgkin’s disease, hepatic metastases of solid tumors).
  • The drug appears to be more effective in reducing fever associated with neoplasms than fever caused by infections. In adults with fever associated with various neoplasms, indomethacin has effectively controlled fever that had not responded to other antipyretics (e.g., aspirin, acetaminophen), antineoplastic agents, and/or anti-infective agents. Indomethacin has been reported to have a greater antipyretic effect than aspirin in children with infection. However, indomethacin should not be used routinely as an antipyretic because of potentially serious adverse effects.
  • Indomethacin has been used occasionally to relieve severe primary dysmenorrhea.
  • Indomethacin has been used for symptomatic treatment of Bartter’s syndrome. However, because of potentially serious adverse effects of indomethacin, the drug may not be suitable for the long-term therapy necessary to control the disease; use of other NSAIDs such as ibuprofen is being evaluated.
  • Indomethacin also has been used successfully in the treatment of idiopathic pericarditis and postpericardiotomy pericarditis in children (11-15 years of age).
  • Indomethacin has also been used for symptomatic treatment of traumatic synovitis, tennis elbow, athletic injuries, psoriatic arthritis, juvenile arthritis, Paget’s disease, mild uveitis, and acute pseudogout.
  • Indomethacin is used to reduce the pain, fever, and inflammation of pericarditis, including that associated with myocardial infarction or occurring during maintenance hemodialysis.
