In a sudden, tragic (for some people...) turn of events, the FDA is recommending that Darvocet and Darvon be pulled from the market, and are no longer prescribed for patients.

See here for the CNN article.

This is going to have some interesting fallout... There are some people who are very much attached to their Darvocet.  I'll be interested to see what kind of chronic pain medicine is used to replace it. 

Good luck to the people having to deal with THAT issue!  Glad I don't have any patients on Darvocet...
