Administration said on Saturday certain lots of the supplement
L-citrulline, used to treat genetic disorders found mostly in
children, sold by compounding firm Medisca Inc were found to
contain none of the drug, and warned doctors and patients not to
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."
