Contraindications

When used for self-medication, do not use if you are hypersensitive to any other pain reliever/fever reducer, in children <12 years of age, prior to or following cardiac surgery, or in combination with or within 14 days of stopping a monoamine oxidase inhibitor.

Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

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. Do not use in patients who experience bronchospasm, asthma, rhinitis, or urticaria with nonsteroidal anti-inflammatory drug (NSAID) or aspirin therapy.

• Cardiovascular events: NSAIDs cause an increased risk of serious (and potentially fatal) adverse cardiovascular thrombotic events, including fatal myocardial infarction (MI) and stroke. Risk may occur early during treatment and may increase with duration of use. New-onset hypertension or exacerbation of hypertension may occur (NSAIDs may also impair response to angiotensin-converting enzyme (ACE) inhibitors, thiazide diuretics, or loop diuretics); may contribute to cardiovascular events; monitor BP; 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 (FDA 2015). Avoid use in patients with a 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 that 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.

• Drug reaction with eosinophilia and systemic symptoms: Potentially serious, sometimes fatal, drug reaction with eosinophilia and systemic symptoms (DRESS), also known as multiorgan hypersensitivity reactions, has been reported with NSAIDs. Monitor for signs and symptoms (eg, fever, rash, lymphadenopathy, eosinophilia) in association with other organ system involvement (eg, hepatitis, nephritis, hematological abnormalities, myocarditis, myositis). Early symptoms of hypersensitivity reaction (eg, lymphadenopathy, fever) may occur without rash; discontinue therapy and further evaluate if DRESS is suspected.

• Gastrointestinal events: NSAIDs cause an increased risk of serious GI inflammation, ulceration, bleeding, and perforation (may be fatal); elderly patients and patients with 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 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.

• 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).

• Hyperkalemia: NSAID use may increase the risk of hyperkalemia, particularly in elderly patients, diabetic patients, renal disease, and with concomitant use of other agents capable of inducing hyperkalemia (eg, ACE-inhibitors). Monitor potassium closely.

• 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 elderly patients are at greater risk of renal toxicity. Rehydrate patient before starting therapy; monitor renal function closely.

• 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:

• Aseptic meningitis: May increase the risk of aseptic meningitis, especially in patients with systemic lupus erythematosus (SLE) and mixed connective tissue disorders.

• Asthma: Do not administer to patients with aspirin-sensitive asthma; severe 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 2020). 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).

• Diabetes: Use with caution in patients with diabetes mellitus.

• Hepatic impairment: Use with caution in patients with hepatic impairment. Patients with advanced hepatic disease are at an increased risk of GI bleeding with NSAIDs.

• Increased intraocular pressure/glaucoma: Use with caution in patients with increased intraocular pressure or angle-closure glaucoma.

• Prostatic hyperplasia/urinary obstruction: Use with caution in patients with prostatic hyperplasia and/or urinary obstruction.

• Renal impairment: Use with caution in patients with renal impairment.

• Thyroid disease: Use with caution in patients with thyroid disease.

Special populations:

• Older adult: Use with caution in older adult patients; may be more sensitive to adverse effects.

Other warnings/precautions:

• Self-medication (OTC use): When used for self-medication (OTC), contact a health care provider before use if you have a breathing problem such as emphysema or chronic bronchitis or have a history of stomach problems such as heartburn. Discontinue use and contact health care provider if signs of stomach bleeding occur (eg, feeling faint, vomiting blood, bloody or black stools); if symptoms of heart problems or stroke occur (eg, chest pain, difficulty breathing, weakness in one part or side of the body, slurred speech, leg swelling); fever gets worse or lasts >3 days; nasal congestion lasts >7 days; redness or swelling is present in the painful area; nervousness, dizziness or sleepiness occurs; symptoms continue or get worse; or if any new symptoms occur. Avoid alcoholic beverages.

Medication Safety Issues
Older Adult: High-Risk Medication:

Beers Criteria: Chlorpheniramine, a first-generation antihistamine, is identified in the Beers Criteria as a potentially inappropriate medication to be avoided in patients 65 years and older (independent of diagnosis or condition) due to its potent anticholinergic properties resulting in increased risk of confusion, dry mouth, constipation, and other anticholinergic effects or toxicity; use should also be avoided due to reduced clearance with advanced age and tolerance associated with use as a hypnotic. Exposure to concurrent anticholinergic drugs also increases risk of falls, delirium, and dementia; consider total anticholinergic burden when conducting medication reviews (Beers Criteria [AGS 2023]).

Beers Criteria: Ibuprofen is identified in the Beers Criteria as a potentially inappropriate medication to be avoided for chronic use in patients 65 years and older (unless alternative agents ineffective and patient can receive concomitant gastroprotective agent) due to increased risk of GI bleeding and peptic ulcer disease in older adults in high risk category (eg, older than 75 years of age or receiving concomitant oral/parenteral corticosteroids, anticoagulants, or antiplatelet agents). In addition, avoid for short-term scheduled use in combination with oral/parenteral corticosteroids, anticoagulants, or antiplatelet agents unless alternatives are ineffective and patient can receive concomitant gastroprotective agent (Beers Criteria [AGS 2023]).
