Impurities & degradation products

An impurity or degradation product above its limit - other than nitrosamines. Unexpected substances in a batch can make it unsafe or less effective, even when the active ingredient is present.

704 FDA drug recalls with this cause, newest first.

Every drug has a specification for how much of each impurity or breakdown product it may contain. These recalls are lots that exceeded one of those limits - often a related compound formed during manufacturing or storage, or an out-of-specification result found during routine stability testing. Nitrosamine impurities are common enough to get their own category; everything else lands here.
