Macleods Pharma Usa Inc: Losartan Potassium Tablets Recalled Due to Potentially Harmful NMBA Impurity

Sign in to monitor this recall

Summary

Macleods Pharma USA Inc. is recalling approximately 368,691 bottles of Losartan Potassium and Losartan Potassium/Hydrochlorothiazide tablets because an impurity called N-Nitroso-N-methyl-4-aminobutyric acid (NMBA) was detected in the active ingredient. This recall affects several strengths and bottle sizes, including 50 mg, 50 mg/12.5 mg, 100 mg/12.5 mg, and 100 mg/25 mg. Consumers should not stop taking their blood pressure medication without consulting a doctor first, as the risk of stopping the medication suddenly may be greater than the risk of the impurity.

Risk

The impurity NMBA is a known environmental contaminant and potential human carcinogen, meaning long-term exposure could increase the risk of cancer. While no adverse events have been reported for this specific recall, the chemical was found at levels exceeding the FDA's acceptable daily intake limits.

What You Should Do

  1. Identify your medication by checking the NDC number and lot codes on the bottle label. Affected products include Losartan Potassium (NDC 33342-045-10, 33342-045-44) and Losartan Potassium/HCTZ (NDC 33342-050-10, 33342-051-10, 33342-052-10).
  2. Check for specific lot codes and expiration dates such as BLI711A (Nov 2019), BLK719A through BLK826A (Sep 2019 to Oct 2021), BLL801A through BLL803A (Dec 2019), and BLM716A through BLM827A (Jul 2019 to Sep 2021).
  3. Do NOT stop taking your medication immediately. Contact your healthcare provider or pharmacist to discuss an alternative treatment or replacement before you stop taking the recalled drug.
  4. Return any unused, affected medication to the pharmacy where you purchased it to receive a refund and further instructions.
  5. Contact Macleods Pharma USA Inc. or the manufacturer for additional information regarding the return process and product quality questions.
  6. Contact the FDA Consumer Complaint hotline at 1-888-723-3332 (1-888-SAFEFDA) or visit www.fda.gov/safety/recalls for additional questions.
