Bisoprolol Fumarate and Hydrochlorothiazide tablets

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

Why it was recalled

cGMP Deviations: recall due to not meeting the N-Nitroso Bisoprolol impurity specification limits.

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.

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.
