Darvon, Darvocet Recalls Lead to Voluntary Withdrawals of Generic Versions


Balacet pulled from shelves after Darvon / Darvocet recallCornerstone Therapeutics announced this week that it would voluntarily withdraw Balacet® 325 and additional propoxyphene medications from the marketplace. The Cornerstone Therapeutics recall follows the FDA’s agreement with Xanodyne Pharmaceuticals, Inc. to withdraw name brand versions of propoxyphene: namely, Darvon®, Darvon-N®, and Darvocet-N®.

Last Friday, these painkillers were pulled from the market by Xanodyne because the drugs can cause fatal heart rhythms. The FDA said that 10 million patients took Darvon or a generic version in 2009 and 18 million prescriptions were dispensed.

"These new heart data significantly alter propoxyphene’s risk-benefit profile. The drug’s effectiveness in reducing pain is no longer enough to outweigh the drug’s serious potential heart risks," Dr. John Jenkins of the FDA’s Center for Drug Evaluation and Research said in a statement about the drug.

As part of FDA action, generic manufacturers of propoxyphene-containing products (such as Balacet ®)were requested to voluntarily remove their products as well. Propoxyphene is a mild opiate used in the treatment of mild to moderate pain, either when pain is present alone or when it is accompanied by a fever.

Two additional products affected by this decision include Cornerstone’s Propoxyphene Napsylate and Acetaminophen Tablets CIV (100 mg), and Propoxyphene Napsylate and Acetaminophen Tablets CIV (100 mg).

According to the company, net product sales of the affected Cornerstone products for the nine months ended September 30, 2010 were $8.0 million.

    My pharmacist told me about this recall today. He said he had contacted my doctor about switching over to Tylenol #3 (Acetaminophen with codeine) so I suspect that is what will be prescribed instead of Darvocet (propoxyphene napsalate.)

    I took Darvon N 100 for about 18 years from 1977 to around 1994 I stopped at that point in time but started again about 18 months ago. My Dr. substituted Hydrocodone for a replacement to Darvocet N 100. In the early 80’s I developed heart problems arrythmia, congestive heart failure and I now have a pacemaker. I don’t know if my problems directly relate to having taken the Darvocet for so long at a time.
