The New York Times reports:

Some of the antidepressant Paxil CR produced at the plant was ineffective because a layer of active ingredient split from a layer of a barrier chemical during manufacturing, the government said, and some lots contained only the barrier chemical.

This is obviously quite concerning for some of the readers of this site. The good news is that the drugs were all manufactured between 5 and 9 years ago, so you probably don't have any more of it. Please read the press release for more information.
