In premarketing clinical trials, serum aminotransferase elevations occurred in up to 10% of patients on flavocoxid therapy, but elevations above 3 times the upper limit of normal occurred in only 1% to 2% of recipients. Since its release, however, there have been several reports of clinically apparent acute liver injury attributed to flavocoxid. Most cases have occurred in women, who perhaps are more likely to use flavocoxid. The time to onset was 1 to 5 months, and the pattern of enzyme elevations was usually hepatocellular or mixed. Most cases were moderate in severity and no instance of acute liver failure or death has been reported. Resolution upon stopping flavocoxid occurred in 1 to 3 months. Immunoallergic features were present in some patients, but were mild and autoantibodies were not common. At least one instance of recurrence upon rechallenge has been reported.

Flavocoxid is a medical food consisting of plant derived flavonoids which have antiinflammatory activity and are used to treat chronic osteoarthritis. Flavocoxid has been linked to minor elevations in serum enzyme levels during therapy and to rare instances of clinically apparent liver injury.
