Contents

Pharmacology

Decreases inflammation, pain, and fever, probably through inhibition of cyclooxygenase activity and prostaglandin synthesis.

Contraindications

History of significantly impaired renal function; patients with known hypersensitivity to any component of the product; patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs; treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery.

Drug Interactions

Aminoglycosides (eg, gentamicin): Plasma aminoglycoside levels may be elevated.
Angiotensin-converting enzyme (ACE) inhibitors: Antihypertensive effect of ACE inhibitors may be diminished.
Anticoagulants: Coadministration may prolong prothrombin time.
Aspirin: Fenoprofen Cl may be increased; coadministration is not recommended.
Diuretics: Patients treated with fenoprofen may be resistant to the effects of loop diuretics and thiazides.
Hydantoins, sulfonamides, sulfonylureas: Fenoprofen may displace these drugs from their binding site.
Lithium: Renal Cl of lithium may be reduced and plasma levels may be elevated, which may increase the risk of lithium toxicity.
Methotrexate: May increase methotrexate levels.
Phenobarbital: May decrease fenoprofen t ½ . Dosage adjustments of fenoprofen may be required if phenobarbital is added or withdrawn.
SSRIs (eg, fluoxetine, citalopram): The risk of GI effects may be increased.

Laboratory Test Interactions

False elevation in free and total serum T 3 as measured by Amerlex-M kit.
