Understanding Darvocet Heart Arrhythmia’s Dangers
For years before the recall, medical experts had been issuing warnings that Darvon (propoxyphene) and Darvocet (propoxyphene and acetaminophen, the painkiller used in Tylenol) could cause hazardous changes to the electrical functioning of the heart. The FDA even published a report in 2009 that supported these very same fears.Those investigating the relationship between propoxyphene and heart problems arrived at the conclusion that even in so-called therapeutic amounts, Darvon and Darvocet were found to cause negative inotropic effects in some patients. This means that the drugs can cause the muscular contractions of the heart to weaken over time.
When the heart’s contractions become weaker, it sets the stage for dangerous shifts in the user’s normal intervals of heartbeat. According to data published by the FDA, such shifts may include a prolonged PR and/or QT interval, and an expanded QRS complex (see above image).
These symptoms are indicative of Darvocet heart arrhythmia, or in layman’s terms, an irregular heartbeat. This is a serious medical condition that can give rise to sudden and sometimes deadly cardiac arrest. A consumer advocacy association known as Public Citizen had been appealing the FDA for decades to recall Darvocet and Darvon. They estimate that between 1,000 and 2,000 individuals in the United States lost their lives due to Darvocet heart problems over the last five years.
