The FDA said the company is voluntarily recalling
eight lots of the supplement. The agency said it has received
"several adverse event reports associated with Medisca's L-citrulline
"Health care professionals should discontinue dispensing from these
lots, contact patients, and return all unused product to Medisca
Inc. Patients and caregivers should stop using any product with
these lot numbers," the FDA said.
The FDA said testing by Medisca indicated that those lots at issue
did not contain L-citrulline. The agency said L-citrulline is used
to treat certain urea cycle disorders, rare genetic conditions
primarily diagnosed in children.
The company said in a statement that its investigation of the lots
found that they did not contain L-citrulline "and therefore
represent a potential health hazard. These lots should not be used
for any purpose."
