Class II · Moderate risk Terminated Initiated Jun 14, 2019 (7 years ago)

Losartan Potassium

Class II — Moderate risk. May cause temporary or reversible harm; serious harm unlikely.

Why it was recalled

CGMP Deviations: impurity for N-Nitroso-N-methyl-4-aminobutyric acid (NMBA) detected in the active pharmaceutical ingredient (API) used to manufacture finished products.

Cause type: Nitrosamine impurity

Trace nitrosamine impurities such as NDMA, NDEA or NMBA found above the acceptable daily limit. Nitrosamines are probable human carcinogens that can form during manufacturing or storage. This is the cause behind the large valsartan, losartan and ranitidine (Zantac) recalls. All nitrosamine impurity recalls.

FDA recall number
D-1462-2019 · FDA notice

Check, then ask. Class II means harm is possible but usually temporary or reversible. Find the lot number on your package; if it matches, ask your pharmacist about a replacement. Do not simply stop a prescribed medication on your own - the gap can be riskier than the recall. This recall is now terminated, which means the firm has finished removing the affected product; anything on pharmacy shelves today should be unaffected.
