FDA recall number
D-166-2013 · 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.
