“Llorens Urin D/S Tablets Recall: Subpotent/Superpotent Risk.” GovInfoNow, updated October 7, 2026. https://govinfonow.com/recall/41269-llorens-urin-d-s-tablets-recall-subpotent-superpotent-risk. Based on FDA recall #D-0081-2018 (https://api.fda.gov/drug/enforcement.json?search=recall_number:%22D-0081-2018%22&limit=1).

Why it’s dangerous

The FDA found the tablets may be under-dosed (subpotent) or over-dosed (superpotent) compared to the intended strength. This could mean the medication is less effective or more effective than it should be, potentially causing treatment failure or adverse effects.

Who’s affected

People who have the 100-count Urin D/S Tablets with NDC 54859-701-10, lots 22811601 or 22811602, expiring May 2018 or November 2018. Those using the medication for urinary tract infections are most at risk.

How to tell if you have this one

Check for the 100-count bottle labeled 'Urin D/S Tablets Methenamine 81.6 mg, Sodium Biphosphate 40.8 mg, Phenyl Salicylate 36.2 mg, Methylene Blue 10.8 mg'. Look for NDC 54859-701-10, lots 22811601 or 22811602, expiring May 2018 or November 2018.
