cbc.ca- darvon FDA suggests Darvon and Darvocet be taken off the market in the US. Not sure about Canada. I remember being on that one myself back in the day. Either way looks like studies say it is bad for the ticker.
"The U.S. Food and Drug Administration said Friday that Xanodyne Pharmaceuticals has agreed to halt marketing of Darvon and the related brand Darvocet, which have been subject to safety concerns for decades.
The FDA has also called on generic drugmakers to stop marketing low-cost drugs containing the active ingredient in Darvon, called propoxyphene.
About 10 million people in the U.S. received prescriptions for Darvon and related drugs in 2009, according to the FDA.
Friday's action puts the U.S. in line with Britain and the European Union, which previously decided to ban Darvon because of suicides and accidental overdoses. The drug is listed as an approved medication in Health Canada's online database.
FDA officials said they decided to take action based on a recent study showing Darvon interferes with the electrical activity of the heart, causing irregular heart rhythms that can be fatal.
"With the new study results, for the first time we now have data showing that the standard therapeutic dose of propoxyphene can be harmful to the heart," Dr. Gerald Dal Pan, director of FDA's office of surveillance and epidemiology, said in a statement.
