Metformin Extended Release 500mg and 750mg – Marksans Pharma / Time-Cap Labs

October 06, 2020

After notification of any recall, Express Scripts will continue processing new and refill prescriptions with product from non-recalled lots or manufacturers, if available.

On June 5, 2020, Marksans Pharma voluntarily recalled a single lot of Metformin Hydrochloride Extended-Release Tablets, USP 500mg (Lot # XP9004), distributed by Time-Cap Labs Inc. On October 5, Marksans expanded the recall to include an additional 76 unexpired lots of the 500mg and 750mg strengths. These lots were tested and showed results for NDMA, an unexpected impurity, at levels in excess of acceptable limits and are being recalled out of an abundance of caution.
