Naproxen Contraindications
Naproxen is absolutely contraindicated in patients with known hypersensitivity to naproxen, those with a history of asthma/urticaria/allergic reactions to aspirin or other NSAIDs, and for treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery. 1
Absolute Contraindications
Hypersensitivity Reactions
- Known hypersensitivity to naproxen itself 1
- History of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs - severe, rarely fatal anaphylactic-like reactions have been reported in such patients 1
Surgical Contraindication
- Peri-operative pain management in CABG surgery - this is an absolute contraindication with black box warning status 1
Relative Contraindications and High-Risk Situations
Cardiovascular Conditions
- Heart failure - naproxen is contraindicated in patients with heart failure due to fluid retention risk 2
- Hypertension or conditions associated with fluid retention - naproxen should not be used in these patients 2
- Patients with cardiovascular disease or risk factors - while not an absolute contraindication, the FDA black box warning emphasizes increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which may be fatal and increases with duration of use 1
Gastrointestinal Risk Factors
- History of NSAID-associated upper GI bleeding - NSAIDs should be avoided in these patients, though if absolutely necessary, must be combined with proton pump inhibitors or misoprostol 3
- Active peptic ulcer disease - represents a high-risk situation where naproxen use requires extreme caution 3
Renal Disease
- Preexisting renal disease - NSAIDs including naproxen should be avoided when possible to prevent acute renal failure 3
- Cirrhosis - naproxen should not be used in patients with cirrhotic liver disease due to increased risk of bleeding problems and renal failure 3
Hematologic Conditions
- Platelet defects or thrombocytopenia - naproxen should be avoided due to antiplatelet effects 3
- Patients on anticoagulants - while not absolutely contraindicated, concurrent use dramatically increases GI bleeding risk (3-6 fold) and should be avoided when possible 3
Pregnancy Considerations
- Last 6-8 weeks of pregnancy - naproxen should be avoided to prevent prolonged gestation from prostaglandin synthesis inhibition, premature closure of ductus arteriosus, and maternal/fetal complications from antiplatelet activity 3
Clinical Pitfalls to Avoid
The American Heart Association guidelines emphasize that individual patient risk for cardiovascular events must be taken into account for each prescribing situation 4. The ADAPT trial specifically showed increased cardiovascular event risk with naproxen, leading to trial suspension 4.
For patients requiring anticoagulation, the combination with naproxen increases INR by up to 15% and multiplies GI bleeding risk 3-6 fold - if concurrent use is absolutely necessary, appropriate INR monitoring, warfarin dose adjustments, and GI prophylaxis must be initiated 3.
Prescribers must recognize that dyspeptic symptoms do not correlate well with clinically significant ulcerations - absence of GI symptoms does not indicate safety 3.
