Fenoprofen is a nonsteroidal anti-inflammatory drug (NSAID). Fenoprofen calcium is used for symptomatic relief for rheumatoid arthritis, osteoarthritis, and mild to moderate pain. Fenoprofen is marketed in the US as Nalfon.

As of 2015, the cost for a typical month of medication in the United States is 50 to US$100.[1]

Pharmacology[edit]

Decreases inflammation, pain, and fever, probably through inhibition of cyclooxygenase (COX-2 inhibitor) activity and prostaglandin synthesis.

Contraindications[edit]

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.

Adverse effects[edit]

In October 2020, the U.S. Food and Drug Administration (FDA) required the drug label to be updated for all nonsteroidal anti-inflammatory medications to describe the risk of kidney problems in unborn babies that result in low amniotic fluid.[2][3] They recommend avoiding NSAIDs in pregnant women at 20 weeks or later in pregnancy.[2][3]

Drug interactions[edit]

Laboratory test interactions[edit]

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