FDA recall number
D-1435-2014 · FDA notice

Low risk, still worth a check. Class III means the product is unlikely to cause harm but breaks an FDA rule (often labeling). If your lot matches, your pharmacy will normally swap it; there is no need for alarm. This recall is now terminated, which means the firm has finished removing the affected product; anything on pharmacy shelves today should be unaffected.
