For Healthcare Professionals

Applies to flurbiprofen: compounding powder, oral tablet

Gastrointestinal

Gastrointestinal side effects have included dyspepsia (8.7%), diarrhea (7.2%), nausea (5.8%), abdominal pain (4.8%), constipation (3.3%), vomiting, gastritis, and flatulence. More serious gastrointestinal effects include ulcer, gastrointestinal hemorrhage, and bloody diarrhea.

In one safety review, serious gastrointestinal side effects were reported in 1.1% of patients. Duodenal ulcer occurred in 10/4123 patients (0.2%). Clinical gastrointestinal hemorrhage occurred in 5/4123 patients (0.1%). Duration of therapy in these cases was not specified in the review. However, as with other nonsteroidal anti-inflammatory agents, the risk of serious gastrointestinal effects is expected to increase with prolonged duration of therapy.

Patients with a history of serious gastrointestinal events or alcohol abuse are at increased risk for severe gastrointestinal side effects. Flurbiprofen should be used with caution in these patients.

Hepatic

Hepatic side effects have included elevations in liver function tests which may occur in up to 15% of patients. In addition, hepatitis as well as cholestatic and noncholestatic jaundice have been reported.

Elevations in liver function tests to three times normal values occur in approximately 1.1% of patients.

Renal

Renal side effects have included elevations in creatinine and blood urea nitrogen, signs and symptoms of urinary tract infection, hematuria, renal calculi, hemorrhagic cystitis, renal failure, interstitial nephritis, and renal papillary necrosis.

In one safety review, significant elevations in serum creatinine and blood urea nitrogen were reported in 11/3802 (0.3%) patients.

Flurbiprofen may impair the ability of the kidney to cope with low renal blood flow states due to inhibition of prostaglandin-dependent afferent arteriolar vasodilation. Renal function may be further compromised in patients with heart failure, hypovolemia, cirrhosis, nephrotic syndrome, or hypoalbuminemia. Additional risk factor for flurbiprofen-induced renal insufficiency are advanced age and concomitant use of diuretics.

A case-control study suggested that patients who consumed 5000 or more pills containing NSAIDs during their lifetime may be at increased risk of end-stage renal disease.

Hypersensitivity

A 21-year-old female developed a pruritic maculopapular rash 48 hours after taking flurbiprofen (the active ingredient contained in Ansaid) 200 mg for a sore throat. Two days later, the patient further developed angioedema and hypotension. After treatment with intravenous methylprednisolone for 6 days, the affected skin underwent desquamation and healed. Flurbiprofen patch testing produced positive results 48 and 72 hours after application suggesting a type IV hypersensitivity.

Hypersensitivity side effects have included urticaria, bronchospasm, angioedema, cutaneous vasculitis, and anaphylaxis.

Dermatologic

Dermatologic side effects have been reported rarely. These have included rash, pruritus, eczema, photosensitivity, exfoliative dermatitis, and toxic epidermal necrolysis.

Hematologic

Hematologic side effects have included reductions in hemoglobin and hematocrit, iron deficiency anemia, leukopenia, eosinophilia, ecchymoses, and thrombocytopenia. Aplastic anemia and hemolytic anemia have also been reported.

Nervous system

Nervous system side effects have included headache (2.9%), nervousness, insomnia, asthenia, somnolence, malaise, amnesia, depression, confusion, paresthesia, and twitching. Seizures, meningitis, cerebrovascular accident, and subarachnoid hemorrhage have also been reported rarely although causality is unknown. Flurbiprofen (the active ingredient contained in Ansaid) has also been implicated in a case of acute Parkinsonism.

Cardiovascular

Nonsteroidal anti-inflammatory drugs (NSAIDs) may elevate blood pressure and increase the risk for the initiation of antihypertensive therapy. Furthermore, NSAIDs may antagonize the blood pressure lowering effect of antihypertensive medications in patients already being treated with antihypertensive drugs.

Cardiovascular side effects have included edema (3% to 9%). In addition, blood pressure may be elevated by flurbiprofen which may have clinical relevance in patients with other comorbid illnesses.

Other

Other side effects have included tinnitus (1% to 3%), deafness (0.1%), and parosmia (altered sense of smell).

Ocular

Ocular side effects have included visual disturbances and conjunctivitis,
