Warnings/Precautions
Boxed warnings:
• Cardiovascular events: See “Concerns related to adverse effects” below.
• Coronary artery bypass graft surgery: See “Disease-related concerns” below.
• Gastrointestinal events: See “Concerns related to adverse effects” below.
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. Do not use in patients who experience bronchospasm, asthma, rhinitis, or urticaria with NSAID or aspirin therapy.
• Aseptic meningitis: May increase the risk of aseptic meningitis, especially in patients with systemic lupus erythematosus (SLE) and mixed connective tissue disorders.
• Bleeding/hemostasis: 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.
• Cardiovascular events: [U.S. Boxed Warning]: NSAIDs are associated with an increased risk of adverse cardiovascular events, including MI, stroke, and new onset or worsening of pre-existing hypertension. Risk may be increased with duration of use or pre-existing cardiovascular risk factors or disease. Carefully evaluate individual cardiovascular risk profiles prior to prescribing. Use caution with fluid retention, heart failure, or hypertension. Concurrent administration of ibuprofen, and potentially other nonselective NSAIDs, may interfere with aspirin's cardioprotective effect. 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.
• Gastrointestinal events: [U.S. Boxed Warning]: NSAIDs may increase risk of gastrointestinal irritation, inflammation, ulceration, bleeding, and perforation. These events may occur at any time during therapy and without warning. Use caution with a history of GI disease (bleeding or ulcers), concurrent therapy with aspirin, anticoagulants and/or corticosteroids, smoking, use of alcohol, 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.
• Skin reactions: NSAIDs may cause serious skin adverse events including exfoliative dermatitis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN); discontinue use at first sign of skin rash or hypersensitivity.
Disease-related concerns:
• Asthma: Do not administer to patients with aspirin-sensitive asthma; severe bronchospasm may occur. Use caution in patients with other forms of asthma.
• Coronary artery bypass graft surgery: [U.S. Boxed Warning]: Use is contraindicated for treatment of perioperative pain 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 decreased hepatic function. Closely monitor patients with any abnormal LFT. Severe hepatic reactions (eg, fulminant hepatitis, liver failure) have occurred with NSAID use, rarely; discontinue if signs or symptoms of liver disease develop, or if systemic manifestations occur.
• Renal impairment: 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. Patients with impaired renal function, dehydration, heart failure, liver dysfunction, 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. Not recommended for use in patients with advanced renal disease. Long-term NSAID use may result in renal papillary necrosis.
Special populations:
• Elderly: The elderly are at increased risk for adverse effects (especially peptic ulceration, CNS effects, renal toxicity) from NSAIDs even at low doses.
• Pediatrics: Safety and efficacy have not been established in children <2 years of age. Not for self-medication (OTC use) in children <12 years of age.
Other warnings/precautions:
• Self-medication (OTC use): Prior to self-medication, patients should contact healthcare provider if they have had recurring stomach pain or upset, ulcers, bleeding problems, high blood pressure, heart or kidney disease, other serious medical problems, are currently taking a diuretic, or are ?60 years of age. Recommended dosages should not be exceeded, due to an increased risk of GI bleeding. Consuming ?3 alcoholic beverages/day or taking longer than recommended may increase the risk of GI bleeding.
• Surgical/dental procedures: Withhold for at least 4-6 half-lives prior to surgical or dental procedures.

Patient Education
Take this medication exactly as directed; do not increase dose without consulting prescriber. Do not crush tablets. Take with food or milk to reduce GI distress. Maintain adequate hydration (2-3 L/day of fluids) unless instructed to restrict fluid intake. Do not use alcohol, aspirin or aspirin-containing medication, or any other anti-inflammatory medications without consulting prescriber. You may experience drowsiness, dizziness, lightheadedness, or headache (use caution when driving or engaging in tasks requiring alertness until response to drug is known); anorexia, nausea, vomiting, or heartburn (small frequent meals, frequent mouth care, sucking lozenges, or chewing gum may help); or fluid retention (weigh yourself weekly and report unusual [3-5 lb/week] weight gain), GI bleeding, ulceration, or perforation can occur with or without pain; or discontinue medication and contact prescriber if persistent abdominal pain or cramping, or blood in stool occurs. Report breathlessness, respiratory difficulty, or unusual cough; chest pain, rapid heartbeat, palpitations; unusual bruising/bleeding; blood in urine, stool, mouth, or vomitus; swollen extremities; skin rash or itching; acute fatigue; or changes in eyesight (double vision, color changes, blurred vision), hearing, or ringing in ears. Pregnancy/breast-feeding precautions: Notify prescriber if you are or intend to become pregnant. Do not take this drug during last trimester of pregnancy. Consult prescriber if breast-feeding.
Geriatric Considerations
Elderly are a high-risk population for adverse effects from NSAIDs. As much as 60% of the elderly can develop peptic ulceration and/or hemorrhage asymptomatically. The concomitant use of H2 blockers and sucralfate is not effective as prophylaxis with the exception of NSAID-induced duodenal ulcers which may be prevented by the use of ranitidine. Misoprostol and proton pump inhibitors are the only agents proven to help prevent the development of NSAID-induced ulcers. Also, concomitant disease and drug use contribute to the risk for GI adverse effects. Use lowest effective dose for shortest period possible. Consider renal function decline with age. Use of NSAIDs can compromise existing renal function especially when Clcr is ?30 mL/minute. Tinnitus may be a difficult and unreliable indication of toxicity due to age-related hearing loss or eighth cranial nerve damage. CNS adverse effects such as confusion, agitation, and hallucination are generally seen in overdose or high-dose situations, but elderly may demonstrate these adverse effects at lower doses than younger adults.
Anesthesia and Critical Care Concerns/Other Considerations
The 2002 ACCM/SCCM guidelines for analgesia (critically-ill adult) suggest that NSAIDs may be used in combination with opioids in select patients for pain management. Concern about adverse events (increased risk of renal dysfunction, altered platelet function and gastrointestinal irritation) limits its use in patients who have other underlying risks for these events.
In short-term use, NSAIDs vary considerably in their effect on blood pressure. When NSAIDs are used in patients with hypertension, appropriate monitoring of blood pressure responses should be completed and the duration of therapy, when possible, kept short. The use of NSAIDs in the treatment of patients with congestive heart failure may be associated with an increased risk for fluid accumulation and edema; may precipitate renal failure in dehydrated patients. Should not be used to treat perioperative pain after coronary bypass surgery (CABG).
Cardiovascular Considerations
Blood Pressure: In short-term use, NSAIDs vary considerably in their effect on blood pressure. A meta-analysis (Pope, 1993) showed that indomethacin and naproxen had the largest effect on blood pressure. Other NSAIDs, including piroxicam, ibuprofen, and sulindac had less of an effect. Ibuprofen combined with captopril or losartan may attenuate the antihypertensive effects of ACE inhibition or receptor blockade on sitting or 24-hour ambulatory diastolic blood pressure. When NSAIDs are used in patients with hypertension, appropriate monitoring of blood pressure responses should be completed and the duration of therapy, when possible, kept short.
Heart Failure: The use of NSAIDs in the treatment of patients with congestive heart failure may be associated with an increased risk for fluid accumulation and edema. One study showed that NSAID use in elderly patients had an increased risk of hospitalization for heart failure. This study gives compelling reasons to avoid or limit the use of NSAIDs in patients with congestive heart failure, particularly in the elderly population. The ACC/AHA 2005 Heart Failure Guidelines suggest that NSAIDs be avoided or withdrawn whenever possible in patients with current or prior symptoms of heart failure and reduced LVEF.
Risk of Cardiovascular Events: Patients at increased risk of cardiovascular adverse events include patients immediately postoperative (10-14 days) from CABG surgery, and those with existing CAD, CVD, or history of TIA. Prescribers are encouraged to use the lowest effective dose for the shortest duration of time based on individual patient treatment goals. Available evidence reviewed by the FDA does not suggest an increased risk of serious CV events when NSAIDs are given short term and in the lower doses used OTC.
Drug Interactions: Nonsteroidal anti-inflammatory agents, including ibuprofen and naproxen, may diminish the cardioprotective effect of aspirin (Catella-Lawson F, 2001; Capone ML, 2005). It is surmised that ibuprofen may exhibit greater affinity than aspirin for the COX-1 site or if dosed regularly (or prior to aspirin), it would gain access to the active site first. In either case, aspirin's inhibition of COX (irreversible) would be limited in favor of ibuprofen inhibition (reversible). Avoid regular use of NSAIDs (nonselective) if possible. If used occasionally, take after aspirin (immediate release) ingestion.
Dental Health: Effects on Dental Treatment
Key adverse event(s) related to dental treatment: Stomatitis.
Naproxen and naproxen sodium have the potential to interfere with the antiplatelet effect of low-dose aspirin. One study of naproxen and low-dose aspirin has suggested that naproxen may interfere with aspirin's antiplatelet activity when they are coadministered (Steinhubl, 2005). However, naproxen 500 mg administered 2 hours before or after aspirin 100 mg did not interfere with aspirin's antiplatelet effect. The FDA stated that there is no data looking at doses of naproxen <500 mg. Naproxen over-the-counter strength is 220 mg tablets.
The FDA has warned that ibuprofen can interfere with the antiplatelet effect of low-dose aspirin (81 mg/day), potentially rendering aspirin less effective when used for cardioprotection and stroke protection. In situations where these drugs could be used concomitantly, the FDA has proved the following information: Patients who use immediate release aspirin (not enteric-coated aspirin) and take single doses of ibuprofen 400 mg, should dose the ibuprofen at least 30 minutes or longer after aspirin ingestion or more than 8 hours before aspirin ingestion to avoid attenuation of aspirin's effect. Similar recommendations may hold for concomitant may hold for concomitant naproxen and aspirin use.
Dental Health: Vasoconstrictor/Local Anesthetic Precautions
No information available to require special precautions
Mental Health: Effects on Mental Status
Dizziness is common; may cause nervousness; may rarely cause drowsiness, confusion, insomnia, depression, or hallucinations
Mental Health: Effects on Psychiatric Treatment
May rarely cause agranulocytosis; use caution with clozapine and carbamazepine; may decrease lithium clearance resulting in an increase in serum lithium levels and potential lithium toxicity; monitor serum lithium levels
Nursing: Physical Assessment/Monitoring
Evaluate cardiac risk and potential for GI bleeding prior to prescribing this medication. Assess effectiveness and interactions of other medications patient may be taking. Monitor blood pressure at the beginning of therapy and periodically during use. Assess results of laboratory tests, therapeutic effectiveness, and adverse reactions (eg, GI effects, hepatotoxicity, or ototoxicity) at beginning of therapy and periodically throughout therapy. Schedule ophthalmic evaluations for patients who develop eye complaints during long-term NSAID therapy. Assess knowledge/teach patient appropriate use, interventions to reduce side effects, and adverse symptoms to report.
