Darvocet was a brand name for a combination medication that contained the active ingredients propoxyphene and acetaminophen. Propoxyphene is an opioid pain reliever, and acetaminophen is a non-opioid pain reliever and fever reducer. In November 2010, the U.S. Food and Drug Administration (FDA) requested the withdrawal of propoxyphene-containing products, including Darvocet, from the market due to safety concerns. Studies showed that propoxyphene could cause serious and potentially fatal heart rhythm abnormalities. As a result, Darvocet is no longer prescribed or available for use. If you require pain relief or have any medical concerns, I strongly recommend consulting with a healthcare provider who can assess your condition and provide appropriate guidance and alternative treatment options. It is important to prioritize your health and safety by using medications that have been approved and deemed safe by regulatory authorities.
