Limbrel: What’s the Problem?

Marketed by Primus Pharmaceuticals, Limbrel (flavocoxid) was brought to market in 2004. It is currently regulated by the U.S. Food & Drug Administration (FDA) as a medical food. Medical foods are specially formulated and intended for the dietary management of a disease that has distinctive nutritional needs that cannot be met by normal diet alone. Unlike prescription drugs, such products do not have to undergo the FDA’s premarket review, registration or approval process.

Limbrel is available in two dosages (250 and 500 mg) and contains two types of flavonoids, as well as zinc. The product is intended to manage the metabolic processes associated with osteoarthritis.

In early September 2017, the FDA began investigating an increase in Limbrel adverse event reports, including drug-induced liver injury and a lung condition called hypersensitivity pneumonitis. On November 21, 2017, the agency issued a press release that warned consumers not to use Limbrel, after the product had been linked to 194 adverse event reports.

“In 30 of those cases, there was sufficient information for FDA medical experts to determine that Limbrel was likely associated with these adverse events,” the release stated.

That number increased to 200 reports by December 4, 2017.

One December 18, 2017, the FDA sent a letter to Primus Pharmaceuticals formally requesting a Limbrel recall.  The letter indicated that the agency would designate the recall a Class I recall, a category that “represents a serious health hazard which may be life-threatening.”

Primus Pharmaceuticals voluntarily suspended promotion and sale of Limbrel on December 21st. However, the company had not announced a Limbrel recall as of January 2, 2018.

Limbrel Drug-Induced Liver Injury

The FDA’s investigation was not the first to suggest that Limbrel could harm the liver.

In June 2012, a small study published in the Annals of Internal Medicine tied Limbrel to several cases of acute liver injury.

Among 877 patients enrolled in the study, four were diagnosed with liver injury. All were women from 57 to 68 years old, and all developed symptoms and signs of liver injury within 1 to 3 months after initiating flavocoxid. All patients recovered within 3 to 12 weeks after flavocoxid was stopped.

“Our report provides convincing evidence that flavocoxid is capable of causing clinically apparent, acute liver injury,” the authors of the study concluded.

The symptoms of drug-induced liver injury include:

  • Jaundice (yellowing of the skin or eyes)
  • Nausea
  • Fatigue
  • Gastrointestinal discomfort

Patients who experience these symptoms while taking Limbrel should stop using the product and contact their doctors.

Limbrel Hypersensitivity Pneumonitis

Hypersensitivity pneumonitis is a disorder in which the lungs become inflamed due to an allergic reaction to inhaled dust, fungus, molds or chemicals.

Symptoms of the condition vary and may include:

  • Fever
  • Chills
  • Headache
  • Cough
  • Chronic bronchitis
  • Shortness of breath or trouble breathing
  • Weight loss
  • Fatigue

Failure to diagnose hypersensitivity pneumonitis in its early stages may allow the condition to progress to pulmonary fibrosis, a serious disorder marked by scarring in the lungs.

Patients who develop any symptoms of hypersensitivity pneumonitis while using Limbrel should stop taking the product and contact their healthcare provider immediately.
