Darvocet/Darvon Lawsuit Alleges Manufacturer Made False Warranties
Plaintiff Arthur Williams alleges in his recently filed Darvocet/Darvon lawsuit that he is now at risk of heart attack and premature death due to Darvocet arrhythmia. His case alleges that the manufacturers represented and warranted that the pain reliever (propoxyphene) was safe, but that these representations and warranties were false, misleading and inaccurate, and in fact, Darvon/Darvocet was unsafe, unreasonably dangerous, and defective.
Darvocet arrhythmia the turning point in safety issues
Darvocet arrhythmia was the side effect that pushed the FDA over the edge in 2010. For years the agency received requests from concerned citizens and advocacy groups to take the opiate drug off the market due to side effects like Darvocet addiction, overdose and death. Still the FDA maintained that the drug’s effectiveness was worth the risk until in 2009, they finally announced they were looking into the safety issues. Later that same year, the European Medicines Agency (EMEA) called for a withdrawal of all propoxyphene drugs, as did Singapore and New Zealand.
Finally, in October 2010, results from the FDA’s heart study showed that propoxyphene raises the risk of abnormal heart rhythms. A month later, the agency announced a Darvocet and Darvon recall. The recall brought the dangers of the drug to the public, driving thousands to file a Darvon lawsuit.
What is Darvocet arrhythmia?
Darvocet arrhythmia is a condition in which the heart beats with an irregular or abnormal rhythm. The heart may beat too fast (tachycardia), too slow (bradycardia), or irregularly. During an arrhythmia, the heart may not be able to pump enough blood to the rest of the body, and a lack of blood can damage the heart, brain, and other organs.
How does Darvon or Darvocet increase risk of arrhythmia? Studies have shown that at normal doses, they somehow weaken the force of the heart’s muscular contractions. During research, they raised one measurement of the heart’s electrical activity to a magnitude known to increase the risk of serious and even fatal heart rhythm abnormalities. The pain relievers were also shown to cause changes in the heart even if the patient had a healthy heart to start with.
The good news is that the studies do not indicate that Darvocet arrhythmia continues after the patient stops taking the drug. This fact doesn’t help Mr. Williams, however.
Darvon lawsuit alleges negligence
Mr. Williams’ Darvocet lawyer alleges that manufacturer Eli Lilly and Xanodyne are guilty of negligence where Darvon and Darvocet are concerned. Eli Lilly is the original manufacturer of the drug, though the patent was later purchased by Xanodyne.
Eli Lilly has faced other similar complaints, and agreed to pay over $1 billion in a lawsuit for promoting its drug Zyprexa for uses not approved by the FDA. The resolution included a criminal fine of $515 million, the largest ever in a healthcare case.
Whether or not the company will be found similarly at fault in a Darvon lawsuit remains to be seen, though critics say manufacturers knew about the dangerous side effects prior to the Darvocet recall.
