Limbrel Liver Injury

On December 5, 2017, the FDA recalled the osteoarthritis medication, Limbrel. Manufactured by Primus Pharmaceuticals, Limbrel can cause liver injury and other serious adverse events. The agency advised immediate stoppage of the drug.

About Limbrel

Approved by the FDA in 2004, Limbrel (flavocoxid) is a “medical food product” made of plant sources or flavonoids and sometimes zinc glycinate. Patients take a capsule in either 250 or 500 mg daily. According to the manufacturer, the medication works by reducing inflammation. Therefore, the reduced inflammation diminishes swelling and pain associated with osteoarthritis.

The term “medical food” means that a patient can only use the product under the supervision of a physician. According to the Orphan Drug Act, medical food products are for the “dietary management of a disease or condition for which distinctive nutritional requirements, based on recognized scientific principles, are established by medical evaluation.” Medical food, unlike drugs, do not require formal premarket safety studies.

Limbrel Liver Injury

Studies have linked Limbrel to life-threatening medical conditions. The FDA reported that between January 1, 2007, and November 9, 2017, it received almost adverse event reports associated with the products.  These include Limbrel liver injury and hypersensitivity pneumonitis. Hypersensitivity pneumonitis is when the lungs become swollen and irritated due to an allergic reaction from dust, fungus or chemicals. After receiving these reports, in November 2017 the FDA advised Limbrel manufacturer, Primus Pharmaceuticals to recall the product. Primus declined.

Then, in December 2017, the FDA made a formal recall request of both Limbrel250 and Limbrel500 with or without zinc due to Limbrel liver injury risk.

Liver Injury Study

2012 study showed a number of patients developed a liver injury within 12 weeks of beginning Limbrel. All were women with an average age of 61. Ceasing the product reversed the liver injury. All women used Limbrel in doses of 250 to 500 mg twice daily for arthritis or other types of musculoskeletal pain, including low back pain and fibromyalgia. All developed symptoms like jaundice, abdominal pain, fever, and rash. No one required hospitalization, however, two received liver biopsies.

Also, study researchers noted other published clinical trials on flavocoxid reported rare instances of liver toxicity. In one randomized controlled study comparing flavocoxid (500 mg twice daily) to naproxen (500 mg twice daily) for 12 weeks to treat osteoarthritis, 28 of the 220 patients showed evidence of liver problems at week 12. Sixteen took Limbrel while 12 received naproxen.

FDA Warnings About Limbrel

In early September 2017, the FDA began investigating an increase in reports about serious adverse events involving Limbrel. Then, by November the FDA received almost 200 adverse event reports. The reports had enough information to link the drug to liver damage, pancreatitis, and hypersensitivity pneumonitis.

Therefore, the FDA issued a public advisory on Nov. 21, 2017, warning that the use of Limbrel can cause patients to develop severe adverse events, which can be life-threatening, and that all patients should stop taking the drug immediately. Following the warning, the FDA requested the drug’s manufacturer, issue a voluntary recall of the product.

After the company failed to issue a recall, the FDA formally requested that the company stop distribution and issue an immediate recall of the following products:

  • Limbrel (flavocoxid) 250 mg capsules
  • Limbrel250 (250 mg flavocoxid with 50 mg citrated zinc bisglycinate) capsules
  • Limbrel (flavocoxid) 500 mg capsules
  • Limbrel500 (500 mg flavocoxid with 50 mg citrated zinc bisglycinate) capsules

The FDA has recommended a Class I recall of the drug, which represents a serious health hazard that may be life-threatening.

Limbrel Side Effects

Limbrel side effects range from mild to life-threatening. Also, this can be dangerous since many do not experience any noticeable symptoms for a while. Then, when he or she does notice, it could be too late and the patient needs hospitalization.
