For Healthcare Professionals
Applies to naproxen / pseudoephedrine: oral tablet extended release
Cardiovascular side effects have included tachycardia and elevation of blood pressure, which may have clinical relevance in patients with comorbid illnesses. Dyspnea has been reported in patients receiving controlled release naproxen. An increased risk of cardiovascular events has been observed in preliminary study results from a clinical trial conducted by the National Institute of Aging evaluating the use of NSAIDs in patients at risk of developing Alzheimer's disease.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may elevate blood pressure and increase the risk of the initiation of antihypertensive therapy. NSAIDs may antagonize the blood-pressure lowering effect of antihypertensive medications in patients already being treated with antihypertensive drugs.
Pseudoephedrine causes vasoconstriction which generally does not produce hypertension, but may be problematic for patients with preexisting hypertension. Arrhythmias may be produced in predisposed patients. Rarely, pseudoephedrine has been reported to cause coronary artery spasm and chest pain.
Gastrointestinal (GI) side effects have been reported the most frequently with the use of naproxen. These have included constipation (3% to 9%), general abdominal discomfort (3% to 9%), nausea (3% to 9%), dyspepsia (3% to 9%), diarrhea, and stomatitis. Serious gastrointestinal side effects include peptic ulcerations, and, in rare cases, gastrointestinal hemorrhage or perforation. Ulcerative esophagitis, eosinophilic colitis, allergic sialadenitis, and pancreatitis have been reported. Heartburn and stomatitis have been reported in patients receiving the controlled release formulation of naproxen. The GI side effects associated with the use of pseudoephedrine have included anorexia and gastric irritation in approximately 5% of patients. Dry mouth, nose, or throat have occurred in up to 15% of patients.
Patients with a history of serious gastrointestinal events or alcohol abuse are at increased risk for severe gastrointestinal side effects. Naproxen should be used with caution in these patients.
A 52-year-old male developed cutaneous necrotizing vasculitis, renal failure, and nephrotic syndrome following administration of naproxen 250 mg every 12 hours and dicloxacillin 250 mg every six hours for three days for the treatment of a blunt injury to the leg. Renal pathology was suggestive of a hypersensitivity angiitis. Symptoms resolved following discontinuation of naproxen.
Naproxen 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 factors for naproxen-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.
Renal side effects have included the development of mild renal insufficiency, nephrotic syndrome (with or without renal failure), acute renal failure due to tubulointerstitial nephritis, papillary necrosis, and acute tubular necrosis. Hypersensitivity may play a role in some cases of renal failure.
Nervous system side effects have included insomnia in up to 30% of patients taking pseudoephedrine. Tremor, anxiety, nervousness, and headache have also been reported. Depression, dream abnormalities, insomnia, malaise, myalgia, muscle weakness, aseptic meningitis, inability to concentrate, and cognitive dysfunction have been reported with the use of naproxen.
Excessive sun exposure may play a role in cases of skin eruptions resembling porphyria cutanea tarda. Biochemical evidence of porphyria, such as elevated serum porphyrins, is lacking in these cases. Photosensitivity reactions have also been associated with lesions resembling those of epidermolysis bullosa.
Although rarely reported with the use of naproxen, a 14-year-old girl is diagnosed with periareolar fixed drug eruption after taking naproxen during menses for dysmenorrhea.
Dermatologic side effects have included pruritus, ecchymoses, purpura, rash, and photosensitivity. Rare cases of pseudoporphyria cutanea tarda, toxic epidermal necrolysis, generalized bullous fixed drug eruption, erythema multiforme, and Stevens-Johnson syndrome have also been reported. Skin eruptions have been reported in patients receiving the controlled release formulation of naproxen.
Hypersensitivity side effects have been reported rarely. These may result in an erythematous or urticarial rash, angioedema, and bronchospasm, especially in patients with aspirin-sensitive asthma. Anaphylactoid reactions have been reported as well. Hypersensitivity has been implicated in cases of renal failure, pneumonitis, and colitis. Fixed drug eruptions have been reported with the use of pseudoephedrine.
Respiratory side effects have included bronchospasm. Rarely, cases of eosinophilic pneumonitis have been reported.
Several cases of pulmonary infiltration accompanied by eosinophilia have been reported in the literature. Fever, malaise, and respiratory symptoms are typically present. Discontinuation of naproxen results in resolution of symptoms.
Other side effects have included tinnitus, altered hearing, vertigo, visual disturbances, and keratopathy. Increased thirst has been reported in patients receiving the controlled release naproxen.
