Rescuing Patients On Darvon Or Darvocet With Zero Tolerance For Pain
On November 19, 2010 the Food and Drug Administration (FDA) called for a halt in the use of the popular opioid pain relievers Darvocet and Darvon. These products contain the opioid propoxyphene, and it has been used to treat mild to moderate pain for over 50 years. However, concerns have long been raised about the effectiveness of this drug, and the risk of death (accidental and suicide). Darvon and Darvocet were banned in Britain in 2005, followed by the European Union in 2009. Over the past 30 years, the FDA has received numerous petitions to take these drugs off the U.S. market.
Research has shown that Darvon and Darvocet are no more effective for treating moderate pain than over the counter drugs like acetaminophen, aspirin or ibuprofen. Unfortunately, Darvon and Darvocet cause a lot more side effects such as dizziness, drowsiness, nausea and vomiting, hallucinations and constipation (all pretty typical of opioids used to treat pain). But, the side effects don’t stop there. The data is in, and it’s not a pretty picture. A recent study requested by the FDA showed that when used at the recommended doses, Darvon and Darvocet cause significant changes in the electrical activity of the heart, which can lead to a fatal irregularity in your heartbeat, even after only short-term use.
Among those advocating for the removal of these drugs from the market were pharmacists. The American Society of Health-System Pharmacists approved a policy in 2007 advocating for the withdrawal of Darvon and Darvocet from the U.S. market, and recently testified at the FDA Advisory Committee to this effect. As an often overlooked member of the medical team, pharmacists have a vital role to play in providing safe and effective treatments. We serve as the last line of defense against improper or unwise prescribing of drugs — especially those for pain. We are drug experts, and we can help patients and doctors switch from Darvon or Darvocet to safer and more effective treatments. Read more »
