Between January 1, 2007 and November 9, 2017, the Food and Drug Administration (FDA) had received 30 adverse event reports related to elevated liver function tests or acute hypersensitivity pneumonitis associated with the use of Limbrel. An independent review, conducted by Primus, found no basis on which to conclude that Limbrel potentially causes life-threatening adverse effects. 

Nevertheless, at the FDA's request, Primus is recalling all unexpired lots of the following products:

  • Limbrel 250mg capsules, Product Identity Number 68040-601-16 
  • Limbrel250 (250mg flavocoxid with 50mg citrated zinc bisglycinate) capsules, Product Identity Number 68040-605-16
  • Limbrel 500mg capsules, Product Identity Number 68040-602-16
  • Limbrel500 (500mg flavocoxid with 50mg citrated zinc bisglycinate) capsules, Product Identity Number 68040-606-16

The Company is contacting distributors and arranging for return of all recalled products. Patients in possession of the affected products are recommended to discontinue use. 

In a press release, Primus notes that several physicians have provided written testimony to the FDA confirming the benefits and safety of Limbrel, especially for elderly patients with comorbidities who cannot take nonsteroidal antiinflammatory drugs (NSAIDs) and do not wish to take opioids. The Company will be working with the FDA to bring the product back to market as soon as possible
