The maker of Darvon and Darvocet have announced on Friday that it will stop marketing the painkillers in the U.S. because of a new study that links the active ingredient in the drugs to serious and sometimes fatal heart rhythm abnormalities.

Xanodyne Pharmaceuticals Inc. have agreed to the ban at the request of the Food and Drug Administration (FDA) which also asked makers of generic versions of the drugs’ core compound, known as propoxyphene, to stop selling it in the U.S.

The decision to ban propoxyphene in the U.S. comes after the regulatory ban in Britain and the European Union which pulled the drug from the market more than a year ago.

The suggested study by the US before it banned it took a stand to ban the drug, showed that the drug increases risks for heart arrhythmias even in the healthy patients.

The FDA urged doctors to stop prescribing it immediately but had advised patients to continue taking propoxyphene, till their doctors prescribe them an alternative medicine.

Note: This information is highly valuable to those residing in countries where the drug has not been banned yet. Some doctors might still be unaware of this recent development and would be continuing in prescribing this medicine. So in case your doctor had prescribed you propoxyphene or you face a prescription in the future, please ask the doctor to prescribe an alternative to it.
