Indomethacin Disease Interactions

There are 13 disease interactions with indomethacin.

Major

NSAIDs (applies to indomethacin) asthma

Major Potential Hazard, High plausibility.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are contraindicated in patients with history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs; severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients. A subpopulation of patients with asthma may have aspirin-sensitive asthma which may include chronic rhinosinusitis complicated by nasal polyps, severe potentially fatal bronchospasm, and/or intolerance to aspirin and other NSAIDs. Since cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, therapy with any NSAID should be avoided in patients with this form of aspirin sensitivity. NSAIDs should be used with caution in patients with preexisting asthma (without known aspirin sensitivity), and these patients should be monitored for changes in the signs and symptoms of asthma.

Major

NSAIDs (applies to indomethacin) fluid retention

Major Potential Hazard, Moderate plausibility. Applicable conditions: Congestive Heart Failure, Hypertension

Fluid retention and edema have been reported in association with the use of nonsteroidal anti-inflammatory drugs (NSAIDs). Therapy with NSAIDs should be administered cautiously in patients with preexisting fluid retention, hypertension, or a history of heart failure. Blood pressure and cardiovascular status should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.

Major

NSAIDs (applies to indomethacin) GI toxicity

Major Potential Hazard, High plausibility. Applicable conditions: Peptic Ulcer, Gastrointestinal Hemorrhage, Gastrointestinal Perforation, Duodenitis/Gastritis, History - Peptic Ulcer, Alcoholism, Colitis/Enteritis (Noninfectious), Colonic Ulceration, Smoking, Intestinal Anastomoses

Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can develop at any time, with or without warning symptoms. NSAIDs should be used with caution in patients with history of peptic ulcer disease and/or GI bleeding, as these patients had a greater than 10-fold increased risk for developing a GI bleed compared to patients without these risk factors. Caution is also advised if NSAIDs are prescribed to patients with other factors that increase risk of GI bleeding, such as: prolonged NSAID therapy; concomitant use of oral corticosteroids, antiplatelet agents (e.g., aspirin), anticoagulants, selective serotonin reuptake inhibitors; alcohol use; smoking; history of gastrointestinal surgery or anastomosis, older age; poor general health status; and advanced liver disease and/or coagulopathy. Particular vigilance is necessary when treating elderly or debilitated patients since most postmarketing reports of fatal GI events occurred in these patients.

Major

NSAIDs (applies to indomethacin) rash

Major Potential Hazard, High plausibility. Applicable conditions: Dermatitis - Drug-Induced

Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious skin adverse reactions (e.g., Stevens-Johnson syndrome, toxic epidermal necrolysis, and exfoliative dermatitis), which can be fatal. These serious events may occur without warning. Patients should be advised to discontinue the NSAID and seek medical attention promptly at the first sign of skin rash or any other sign of hypersensitivity. NSAIDs are contraindicated in patients with previous serious skin reactions to these drugs.

Major

NSAIDs (applies to indomethacin) renal toxicities

Major Potential Hazard, High plausibility. Applicable conditions: Renal Dysfunction, Dehydration, Hyponatremia, Congestive Heart Failure, Liver Disease

Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) has resulted in renal papillary necrosis and other renal injury. Renal toxicity has been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion: in such patients, NSAIDs may cause a dose-dependent reduction in prostaglandin synthesis and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk for this reaction include the elderly, those with impaired renal function, dehydration, hypovolemia, heart failure, or liver dysfunction, and those taking diuretics, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers; discontinuation of NSAID therapy will usually lead to recovery to the pretreatment state. No information is available regarding use NSAIDs in patients with advanced renal disease; the renal effects of NSAIDs may hasten the progression of renal dysfunction in patients with preexisting renal disease. Volume status should be corrected in dehydrated or hypovolemic patients prior to initiating treatment. Renal function should be monitored during therapy in patients with renal or liver dysfunction, heart failure, dehydration, or hypovolemia. NSAIDs should be avoided in patients with advanced renal disease unless the benefits are expected to outweigh the risk of worsening renal function; if an NSAID is used in such patients, they should be monitored for signs of worsening renal function.

Major

NSAIDs (applies to indomethacin) thrombosis

Major Potential Hazard, High plausibility. Applicable conditions: Cerebrovascular Insufficiency, History - Cerebrovascular Disease, History - Myocardial Infarction, Ischemic Heart Disease

Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use. Clinical trials of several cyclooxygenase-2 (COX-2) selective and nonselective NSAIDs of up to 3 years duration have supported this increased risk. It is unclear from available data if the risk for cardiovascular thrombotic events is similar for all NSAIDs. Therapy with NSAIDs should be administered cautiously in patients with a history of cardiovascular or cerebrovascular disease. Patients should be treated with the lowest effective dosage for the shortest duration necessary. Appropriate antiplatelet therapy should be administered to patients requiring cardioprotection; however, there is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious cardiovascular thrombotic events associated with NSAID use, while the risk of serious gastrointestinal events is increased. Physicians and patients should remain alert for the development of adverse cardiovascular events throughout the entire duration of therapy, even without prior cardiovascular symptoms. Patients should be advised to promptly seek medical attention if they experience symptoms of cardiovascular thrombotic events (including chest pain, shortness of breath, weakness, or slurring of speech).

NSAIDs are contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Two large clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10 to 14 days following CABG surgery found an increased incidence of myocardial infarction and stroke.

The use of NSAIDs should be avoided in patients with a recent myocardial infarction unless the benefits are expected to outweigh the risk of recurrent cardiovascular thrombotic events. If an NSAID is used in patients with a recent myocardial infarction, they should be monitored for signs of cardiac ischemia.

Indomethacin (applies to indomethacin) CNS effects

Moderate Potential Hazard, Low plausibility. Applicable conditions: Parkinsonism, Psychosis, Seizures, Depression

The use of indomethacin has been reported to aggravate depression or other psychiatric disturbances, epilepsy, and parkinsonism. Therapy with indomethacin should be administered cautiously in patients with a history of these conditions. If severe CNS adverse reactions develop, indomethacin should be withdrawn.

Moderate

NSAIDs (applies to indomethacin) anemia

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Bleeding

Anemia has been reported in patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs). This may be due to fluid retention, occult/gross blood loss, or an incompletely described effect on erythropoiesis. Hemoglobin or hematocrit should be monitored in patients with any signs/symptoms of anemia or blood loss, especially during long-term therapy. NSAIDs may increase risk of bleeding events; comorbid conditions (e.g., coagulation disorders; concomitant use of warfarin/other anticoagulants, antiplatelet agents, serotonin/serotonin norepinephrine reuptake inhibitors) may increase this risk, and patients with these conditions should be monitored for signs of bleeding. Therapy with NSAIDs should be administered cautiously in patients with or predisposed to anemia. Clinical monitoring of hematopoietic function may be appropriate, particularly during chronic therapy.

Moderate

NSAIDs (applies to indomethacin) heart failure

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Congestive Heart Failure

Fluid retention and edema have been observed in patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs), including some topical formulations. These drugs should be avoided in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure. If an NSAID is used in patients with severe heart failure, they should be monitored for signs of worsening heart failure.

Moderate

NSAIDs (applies to indomethacin) hepatotoxicity

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Liver Disease

Borderline elevations of 1 or more liver tests may occur in up to 15% of patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs). These laboratory abnormalities may progress, remain unchanged, or regress with continuing therapy. Elevations of ALT or AST (at least 3 times the upper limit of normal) have been reported in about 1% of patients in clinical trials. In addition, rare (sometimes fatal) cases of severe hepatotoxicity, including liver necrosis, hepatic failure, jaundice, and fulminant hepatitis have been reported. Therapy with NSAIDs should be administered cautiously in patients with preexisting liver disease. Periodic monitoring of liver function is recommended during prolonged therapy. NSAIDs are also highly protein-bound and some are extensively metabolized by the liver. Metabolic activity and/or plasma protein binding may be altered in patients with hepatic impairment. A dosage reduction may be required in some cases.

Moderate

NSAIDs (applies to indomethacin) hyperkalemia

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Renal Dysfunction

Increases in serum potassium concentration (including hyperkalemia) have been reported with use of nonsteroidal anti-inflammatory drugs (NSAIDs), even in some patients without renal impairment. In patients with normal renal function, these effects have been attributed to a hyporeninemic-hypoaldosteronism state. Caution is advised in patients with hyperkalemia.

Moderate

NSAIDs (applies to indomethacin) hypertension

Moderate Potential Hazard, Moderate plausibility.

Nonsteroidal anti-inflammatory drugs (NSAIDs), including topicals, can lead to new onset of hypertension or worsening of preexisting hypertension, either of which can contribute to the increased incidence of cardiovascular events. NSAIDs should be used with caution in patients with hypertension. Blood pressure should be monitored closely during the initiation of NSAID therapy and throughout the course of therapy.

Moderate

NSAIDs (applies to indomethacin) platelet aggregation inhibition

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Coagulation Defect, Thrombocytopathy, Thrombocytopenia, Bleeding, Vitamin K Deficiency

Nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly inhibit platelet adhesion and aggregation and may prolong bleeding time in some patients. With the exception of aspirin, the platelet effects seen with most NSAIDs at usual recommended dosages are generally slight and of relatively short duration but may be more pronounced in patients with underlying hemostatic abnormalities. Thrombocytopenia has also been reported rarely during NSAID use. Therapy with NSAIDs should be administered cautiously in patients with significant active bleeding or a hemorrhagic diathesis, including hemostatic and/or coagulation defects associated with hemophilia, vitamin K deficiency, hypoprothrombinemia, thrombocytopenia, thrombocytopathy, or severe hepatic impairment. NSAIDs that selectively inhibit cyclooxygenase-2 (i.e., COX-2 inhibitors) do not appear to affect platelet function or bleeding time at indicated dosages and may be preferable if risk of bleeding is a concern.
