Version May 2024
Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction (MI), and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use.
Fenoprofen is contraindicated in the setting of coronary artery bypass graft (CABG) surgery.
NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events, including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events.
Note: Use the lowest effective dose for the shortest possible duration.
Osteoarthritis, rheumatoid arthritis: Oral: 400 to 600 mg 3 to 4 times daily; adjust dose based on patient response; maximum dose: 3,200 mg/day.
Pain (mild to moderate): Oral: 200 mg every 4 to 6 hours as needed.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no dosage adjustments provided in the manufacturer's labeling; use with caution. Use is contraindicated in patients with significantly impaired kidney function.
Dialysis: Not removed by hemodialysis.
There are no dosage adjustments provided in the manufacturer's labeling; use with caution.
Unless alternative agents are ineffective and a gastroprotective agent can be administered, avoid short-term scheduled use in combination with corticosteroids, anticoagulants, or antiplatelet agents or chronic use with or without medications that increase risk for bleeding (Ref).

Hypersensitivity to fenoprofen (eg, anaphylactic reactions, serious skin reactions) or any component of the formulation; history of asthma, urticaria, or allergic-type reaction to aspirin or other nonsteroidal anti-inflammatory drugs; in the setting of coronary artery bypass graft surgery; significantly impaired kidney function.
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 nonsteroidal anti-inflammatory drug (NSAID) or aspirin therapy.
• Cardiovascular events: [US Boxed Warning]: 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 cardiovascular events (which may occur early during treatment) was higher in patients with known cardiovascular disease or risk factors. 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 patients with heart failure (FDA 2015). 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). If visual disturbances occur, preform ophthalmologic exam.
• 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.
• GI events: [US Boxed Warning]: 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. 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 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.
• 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 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:
• Asthma: Contraindicated in 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, and leaks 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).
• 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.
• Hearing impairment: Periodically monitor auditory function in patients with hearing impairment during prolonged therapy.
• 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.
• Renal impairment: Discontinue use with persistent or worsening abnormal renal function tests. Use is contraindicated in patients with significantly impaired kidney function.
Other warnings/precautions:
• Surgical/dental procedures: Withhold for at least 4 to 6 half-lives prior to surgical or dental procedures.

Zanubrutinib: May enhance the antiplatelet effect of Agents with Antiplatelet Properties. Risk C: Monitor therapy
Fenoprofen peak serum levels may be decreased if taken with food; total amount absorbed is not affected. Management: Administer with food to minimize stomach upset.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may delay or prevent rupture of ovarian follicles. This may be associated with infertility that is reversible upon discontinuation of the medication. Consider discontinuing use in patients having difficulty conceiving or those undergoing investigation of fertility.
Based on available information, NSAIDs can be continued in males with rheumatic and musculoskeletal diseases who are planning to father a child (ACR [Sammaritano 2020]).
The use of nonsteroidal anti-inflammatory drugs (NSAIDs) close to conception may be associated with an increased risk of miscarriage due to cyclooxygenase-2 inhibition interfering with implantation (Bermas 2014; Bloor 2013).
Birth defects have been observed following in utero NSAID exposure in some studies; however, data are 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 (Bermas 2014; Bloor 2013).
Maternal NSAID use may cause fetal renal dysfunction leading to oligohydramnios. Although rare, this may occur as early as 20 weeks' gestation and is more likely to occur with prolonged maternal use. Oligohydramnios may be reversible following discontinuation of the NSAID (Dathe 2019; FDA 2020). In addition, nonclosure of the ductus arteriosus postnatally may occur and be resistant to medical management (Bermas 2014; Bloor 2013).
Maternal use of NSAIDs should be avoided beginning at 20 weeks' gestation. If NSAID use is necessary between 20 and 30 weeks' gestation, limit use to the lowest effective dose and shortest duration possible; consider ultrasound monitoring of amniotic fluid if treatment extends beyond 48 hours, and discontinue the NSAID if oligohydramnios is found (FDA 2020). Because NSAIDs may cause premature closure of the ductus arteriosus, prescribing information for fenoprofen specifically states use should be avoided starting at 30 weeks' gestation.
Based on available information, NSAIDs can be continued during the first 2 trimesters of pregnancy in patients with rheumatic and musculoskeletal diseases; use in the third trimester is not recommended (ACR [Sammaritano 2020]).
NSAIDs may be used as part of a multimodal approach to pain relief following cesarean delivery (ACOG 2019).
Fenoprofen is present in breast milk.
Women were given fenoprofen 600 mg every 6 hours for 4 days postpartum. Concentrations in breast milk were generally below the limit of quantification. When detected, milk concentrations were 1/60 of the maternal plasma (Rubin 1974).
Nonopioid analgesics are preferred for breastfeeding patients who require pain control peripartum or for surgery outside of the postpartum period (ABM [Martin 2018]; ABM [Reece-Stremtan 2017]). Nonsteroidal anti-inflammatory drugs (NSAIDs) are considered compatible for the treatment of rheumatic and musculoskeletal diseases in lactating patients; agents with a short half-life and established safety data in infants may be preferred (ACR [Sammaritano 2020]).
According to the manufacturer, the decision to continue or discontinue breastfeeding during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and benefits of treatment to the mother. Maternal use of NSAIDs should be avoided if the breastfeeding infant has platelet dysfunction, thrombocytopenia, or a ductal-dependent cardiac lesion (ABM [Martin 2018]; ABM [Reece-Stremtan 2017]; Bloor 2013).
May be taken with food or milk.
CBC, chemistry profile (periodically during long-term therapy); liver function tests; renal function (urine output, BUN, creatinine); signs/symptoms of bleeding (occult or gross blood loss); blood pressure (at initiation and during therapy); signs/symptoms of fluid retention; audiogram (in patients with baseline hearing impairment on long-term therapy).
Reversibly inhibits cyclooxygenase-1 and 2 (COX-1 and 2) enzymes, which results in decreased formation of prostaglandin precursors; has antipyretic, analgesic, and anti-inflammatory properties
Other proposed mechanisms not fully elucidated (and possibly contributing to the anti-inflammatory effect to varying degrees), include inhibiting chemotaxis, altering lymphocyte activity, inhibiting neutrophil aggregation/activation, and decreasing proinflammatory cytokine levels.
