Food and Drug Administration officials said this week that lots of the supplement L-citrulline sold by the compounding firm Medisca were found not to contain the drug at all. The company voluntarily recalled eight lots of the supplement, which is supplied to hospital and retail pharmacies nationwide.
“Health care professionals should discontinue dispensing from these lots, contact patients and return all unused product to Medisca Inc.,” FDA officials said in a notice.
L-citrulline is an amino acid used to treat certain urea cycle disorders, a genetic problem in which the body lacks one of six enzymes that help clear ammonia from the blood. Without enough L-citrulline, the ammonia builds up, potentially causing life-threatening brain damage and death.
