Lupin Pharmaceuticals Inc.: Metformin Hydrochloride Extended-Release Tablets Recalled for NDMA Impurity

Sign in to monitor this recall

Summary

Lupin Pharmaceuticals Inc. has voluntarily recalled 492,858 bottles of Metformin Hydrochloride Extended-Release Tablets (500 mg and 1000 mg), a medication used to control blood sugar in adults with type 2 diabetes. The recall was initiated because FDA laboratory testing found levels of N-Nitrosodimethylamine (NDMA) that exceed the acceptable daily intake limit. These prescription medications were distributed nationwide in bottles of 60, 90, or 100 tablets. Consumers should contact their healthcare provider or pharmacist for guidance on continuing their treatment or obtaining a replacement.

Risk

NDMA is classified as a probable human carcinogen, meaning long-term exposure to levels above the acceptable limit may increase the risk of cancer. While no immediate injuries or adverse events have been reported, the levels detected in these specific batches failed to meet safety standards for pharmaceutical purity.

What You Should Do

  1. Check your prescription bottle label for the product name 'Metformin Hydrochloride Extended-Release Tablets USP' and the manufacturer 'Lupin Limited'.
  2. Verify if your bottle matches one of the following NDC numbers: 68180-338-01 (500mg, 100 count), 68180-339-09 (1000mg, 90 count), 68180-336-07 (500mg, 60 count), or 68180-337-07 (1000mg, 60 count).
  3. Look for the batch numbers printed on the bottle; affected batches include G808201, G807093, G808293, G807619 and many others with expiration dates ranging from July 2020 through February 2022.
  4. Do NOT stop taking your medication without first talking to your doctor or pharmacist, as the risk of suddenly stopping diabetes treatment can be more dangerous than the risk of exposure to the impurity.
  5. Contact your healthcare provider to discuss alternative treatments or to receive a replacement prescription for a batch not affected by this recall.
  6. Return any unused portions of the recalled medication to your pharmacy for a refund and contact Lupin Pharmaceuticals Inc. at their Baltimore, MD location for further instructions.
  7. For additional questions or to report a problem, contact the FDA Consumer Complaint hotline at 1-888-723-3332 (1-888-SAFEFDA) or visit www.fda.gov/safety/recalls.
