Warnings/Precautions

Concerns related to adverse effects:

• Anaphylactoid reactions: Even in patients without prior exposure, anaphylactoid reactions may occur; patients with "aspirin triad" (bronchial asthma, aspirin intolerance, rhinitis) may be at increased risk. Contraindicated in patients who experience bronchospasm, asthma, rhinitis, or urticaria with NSAID or aspirin therapy.
• Cardiovascular events: [US Boxed Warning]: Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious (and potentially fatal) adverse cardiovascular thrombotic events, including MI and stroke. Risk may occur early during treatment and may increase with duration of use. Relative risk appears to be similar in those with and without known cardiovascular disease or risk factors for cardiovascular disease; however, absolute incidence of serious cardiovascular thrombotic events (which may occur early during treatment) was higher in patients with known cardiovascular disease or risk factors and in those receiving higher doses. New onset hypertension or exacerbation of hypertension may occur (NSAIDs may also impair response to ACE inhibitors, thiazide diuretics, or loop diuretics); may contribute to cardiovascular events; monitor blood pressure; use with caution in patients with hypertension. May cause sodium and fluid retention; use with caution in patients with edema. Avoid use in heart failure (ACCF/AHA [Yancy 2013]).Avoid use in patients with recent MI unless benefits outweigh risk of cardiovascular thrombotic events. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of cardiovascular events; alternate therapies should be considered for patients at high risk.
• CNS effects: May cause drowsiness, dizziness, blurred vision, and other neurologic effects which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving). Discontinue use with blurred or diminished vision and perform ophthalmologic exam. Periodically evaluate vision in all patients receiving long term therapy.
• GI events: [US Boxed Warning]: NSAIDs cause increased risk of serious GI inflammation, ulceration, bleeding, and perforation (may be fatal); elderly patients and patients with a history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events. These events may occur at any time during therapy and without warning. Avoid use in patients with active GI bleeding. In patients with a history of acute lower GI bleeding, avoid use of non-aspirin NSAIDs, especially if due to angioectasia or diverticulosis (Strate 2016). Use caution with a history of GI ulcers, concurrent therapy known to increase the risk of GI bleeding (eg, aspirin, anticoagulants and/or corticosteroids, selective serotonin reuptake inhibitors), advanced hepatic disease, coagulopathy, smoking, use of alcohol, or in the elderly or debilitated patients. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of GI adverse events; alternate therapies should be considered for patients at high risk. When used concomitantly with aspirin, a substantial increase in the risk of GI complications (eg, ulcer) occurs; concomitant gastroprotective therapy (eg, proton pump inhibitors) is recommended (Bhatt, 2008).
• Hematologic effects: Platelet adhesion and aggregation may be decreased; may prolong bleeding time; patients with coagulation disorders or who are receiving anticoagulants should be monitored closely. Anemia may occur; patients on long-term NSAID therapy should be monitored for anemia. Rarely, NSAID use has been associated with potentially severe blood dyscrasias (eg, agranulocytosis, thrombocytopenia, aplastic anemia).
• Hepatic effects: Transaminase elevations have been reported with use; closely monitor patients with any abnormal LFT. Rare (sometimes fatal) severe hepatic reactions (eg, fulminant hepatitis, hepatic necrosis, hepatic failure) have occurred with NSAID use; discontinue immediately if clinical signs or symptoms of hepatic disease develop or if systemic manifestations occur.
• Hyperkalemia: NSAID use may increase the risk of hyperkalemia, particularly in the elderly, diabetics, renal disease, and with concomitant use of other agents capable of inducing hyperkalemia (eg, ACE-inhibitors). Monitor potassium closely.
• Pancreatitis: Has been reported; discontinue with suspected pancreatitis.
• Renal effects: NSAID use may compromise existing renal function; dose-dependent decreases in prostaglandin synthesis may result from NSAID use, reducing renal blood flow, which may cause renal decompensation (usually reversible). Patients with impaired renal function, dehydration, hypovolemia, heart failure, hepatic impairment, those taking diuretics and ACE inhibitors, and the elderly are at greater risk of renal toxicity. Rehydrate patient before starting therapy; monitor renal function closely. Long-term NSAID use may result in renal papillary necrosis and other renal injury.
• Skin reactions: NSAIDs may cause potentially fatal serious skin adverse events including exfoliative dermatitis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN); may occur without warning; discontinue use at first sign of skin rash (or any other hypersensitivity).

Disease-related concerns:

• Aseptic meningitis: May increase the risk of aseptic meningitis, especially in patients with systemic lupus erythematosus (SLE) and mixed connective tissue disorders.
• Asthma: Contraindicated in patients with aspirin-sensitive asthma; severe and potentially fatal bronchospasm may occur. Use caution in patients with other forms of asthma.
• Bariatric surgery: Gastric ulceration: Avoid chronic use of oral nonselective NSAIDs after bariatric surgery; development of anastomotic ulcerations/perforations may occur (Bhangu 2014; Mechanick 2013). Short-term use of celecoxib or IV ketorolac are recommended as part of a multimodal pain management strategy for postoperative pain (Chou 2016; Horsley 2019; Thorell 2016).
• Coronary artery bypass graft surgery: [US Boxed Warning]: Use is contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Risk of MI and stroke may be increased with use following CABG surgery.
• Hepatic impairment: Use with caution in patients with hepatic impairment; plasma concentrations may be increased requiring a dosage reduction; monitor closely. Patients with advanced hepatic disease are at an increased risk of GI bleeding with NSAIDs.
• Renal impairment: Use with caution in patients with renal impairment. Avoid use in patients with advanced renal disease; monitor renal function closely if therapy must be initiated.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Elderly: Elderly patients are at greater risk for serious GI, cardiovascular, and/or renal adverse events. Use with caution; initiate dose at the lower end of the dosing range.

Other warnings/precautions:

• Appropriate use: The safety and efficacy have not been established in patients with RA who are designated in the American Rheumatism Association (ARA) classification as functional class IV: incapacitated, largely or wholly bedridden, or confined to a wheelchair; little or no self-care.
• Surgical/dental procedures: Withhold for at least 4 to 6 half-lives prior to surgical or dental procedures.

Monitoring Parameters

CBC, chemistry profile, occult blood loss, and periodic liver function tests; renal function (urine output, serum BUN and creatinine); blood pressure; signs and symptoms of GI bleeding; ophthalmic exam (if ocular complaints develop during treatment)

Pregnancy Considerations

Sulindac crosses the placenta. Birth defects have been observed following in utero NSAID exposure in some studies; however, data is conflicting (Bloor 2013). Nonteratogenic effects, including prenatal constriction of the ductus arteriosus, persistent pulmonary hypertension of the newborn, oligohydramnios, necrotizing enterocolitis, renal dysfunction or failure, and intracranial hemorrhage have been observed in the fetus/neonate following in utero NSAID exposure. In addition, nonclosure of the ductus arteriosus postnatally may occur and be resistant to medical management (Bermas 2014; Bloor 2013). Because they may cause premature closure of the ductus arteriosus, the use of NSAIDs in pregnancy should be avoided. Use of NSAIDs can be considered for the treatment of mild rheumatoid arthritis flares in pregnant women; however, use should be minimized or avoided early and late in pregnancy (Bermas 2014; Saavedra Salinas 2015).

The chronic use of NSAIDs in women of reproductive age may be associated with infertility that is reversible upon discontinuation of the medication (Micu 2011). The use of NSAIDs close to conception may be associated with an increased risk of miscarriage (Bloor 2013; Bermas 2014).
