Warnings
Black Box Warnings
Cardiovascular Risk
- NSAIDs may increase risk of serious cardiovascular thrombotic events, myocardial infarction (MI), & stroke, which can be fatal
- Risk may increase with duration of use
- Patients with risk factors for or existing cardiovascular disease may be at greater risk
- NSAIDs are contraindicated for perioperative pain in the setting of coronary artery bypass graft (CABG) surgery (increased risk of MI & stroke)
Gastrointestinal Risk
- NSAIDs increase risk of serious GI adverse events including bleeding, ulceration, & perforation of the stomach or intestines, which can be fatal
- GI adverse events may occur at any time during use & without warning symptoms
- Elderly patients are at greater risk for serious GI events
Contraindications
Absolute: ASA allergy
Relative: bleeding disorders, duodenal/gastric/peptic ulcer, renal impairment, stomatitis, SLE, ulcerative colitis, upper GI disease, late pregnancy (may cause premature closure of ductus arteriosus)
Cautions
Use caution in asthma (bronchial), cardiac disease, CHF, hepatic impairment, HTN
Long-term administration of NSAIDs may result in renal papillary necrosis and other renal injury; patients at greatest risk include the elderly, or those with impaired renal function, hypovolemia, heart failure, liver dysfunction, salt depletion, and individuals taking diuretics, ACE inhibitors, or ARBs
Drug reaction with eosinophilia and systemic symptoms (DRESS)
- Drug Reaction reported in patients taking NSAIDs; some of these events have been fatal or life-threatening; DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling
- Other clinical manifestations may include hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis; sometimes symptoms of DRESS may resemble an acute viral infection
- Eosinophilia is often present; because this disorder is variable in its presentation, other organ systems not noted here may be involved
- Early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident; if such signs or symptoms are present, discontinue therapy and evaluate the patient immediately
Heart Failure (HF) risk
- NSAIDS have the potential to trigger HF by prostaglandin inhibition that leads to sodium and water retention, increased systemic vascular resistance, and blunted response to diuretics
- NSAIDS should be avoided or withdrawn whenever possible
- AHA/ACC Heart Failure Guidelines; Circulation. 2016; 134
Pregnancy & Lactation
Pregnancy
Data from observational studies regarding other potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive
In animal reproduction studies, embryo-fetal lethality and skeletal abnormalities were noted in offspring of pregnant rabbits following oral administration of fenoprofen during organogenesis at 0.6 times the maximum human daily dose of 3200 mg/day
However, there were no major malformations noted following oral administration of fenoprofen calcium to pregnant rats and rabbits during organogenesis at exposures up to 0.3 and 0.6 times the maximum human daily dose of 3200 mg/day
Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization
In animal studies, administration of prostaglandin synthesis inhibitors such as fenoprofen, resulted in increased pre- and post-implantation loss
Prostaglandins also have been shown to have an important role in fetal kidney development. In published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses
Fetal toxicity
- NSAIDs can cause premature closure of fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment
- Use of NSAIDs at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment
- If an NSAID is necessary at about 20 weeks gestation or later in pregnancy, limit use to lowest effective dose and shortest duration possible; if treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios; if oligohydramnios occurs, discontinue therapy and follow up according to clinical practice
- Use of NSAIDs at about 30 weeks gestation or later in pregnancy increases risk of premature closure of the fetal ductus arteriosus
- Because of these risks, limit dose and duration of use between about 20 and 30 weeks of gestation, and avoid use at about 30 weeks of gestation and later in pregnancy
Labor or Delivery
- There are no studies on the effects of NALFON during labor or delivery; in animal studies, NSAIDS, including fenoprofen, inhibit prostaglandin synthesis, cause delayed parturition, and increase incidence of stillbirth
Reproductive potential
-
Females
- Based on mechanism of action, the use of prostaglandin mediated NSAIDs may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women
- Published animal studies have shown that administration of prostaglandin synthesis inhibitors has the potential to disrupt prostaglandin-mediated follicular rupture required for ovulation
- Small studies in women treated with NSAIDs have also shown a reversible delay in ovulation; consider withdrawal of NSAIDs, in women who have difficulties conceiving or who are undergoing investigation of infertility
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

COMMON BRAND NAME(S): Nalfon
WARNING: Nonsteroidal anti-inflammatory drugs (including fenoprofen) may rarely increase the risk of a heart attack or stroke. This effect can happen at any time while taking this drug but is more likely if you take it for a long time. The risk may be greater in older adults or if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes). Do not take this drug right before or after heart bypass surgery (CABG).Also, this drug may rarely cause serious (rarely fatal) bleeding from the stomach or intestines. This effect can occur without warning symptoms at any time while taking this drug. Older adults may be at higher risk for this effect.Stop taking fenoprofen and get medical help right away if you notice any of these rare but serious side effects: stomach/abdominal pain that doesn't go away, black/tarry stools, vomit that looks like coffee grounds, chest/jaw/left arm pain, shortness of breath, unusual sweating, confusion, weakness on one side of the body, trouble speaking, sudden vision changes.Talk to your doctor or pharmacist about the benefits and risks of taking this drug.
USES: See also Warning section.Fenoprofen is used to relieve pain from various conditions such as headache, dental pain, menstrual cramps, and muscle aches. Fenoprofen is also used to reduce pain, swelling, and joint stiffness from arthritis.Fenoprofen is known as a nonsteroidal anti-inflammatory drug (NSAID). It works by blocking your body's production of certain natural substances that cause inflammation. This effect helps to decrease swelling, pain, or fever.If you are treating a chronic condition such as arthritis, ask your doctor about non-drug treatments and/or using other medications to treat your pain.
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start taking fenoprofen and each time you get a refill.
