Citrulline

Class I — High risk. Reasonable probability of serious harm or death.

Why it was recalled

Labeling: Label Mix-Up: FDA tested samples of API from Medisca, labeled as to contain L-Citrulline, and results revealed no L-Citrulline was present. Levels of N-acetyl-leucine were found instead.

Cause type: Labeling / mix-up

Wrong label, wrong strength, mixed-up products, or packaging errors. One of the most dangerous causes - you can end up taking the wrong drug or the wrong dose. All labeling / mix-up recalls.

FDA recall number
D-0674-2016 · FDA notice

Treat this as urgent. Class I means FDA judged there is a reasonable probability of serious harm. Find the lot number on your package; if it matches the recalled lots, do not take another dose before you have spoken to your pharmacist or prescriber - today, not next week. This recall is now terminated, which means the firm has finished removing the affected product; anything on pharmacy shelves today should be unaffected.
