Darvocet 100 mg was a prescription medication used for short-term relief of mild to moderate pain. It combined propoxyphene, an opioid, with acetaminophen to provide dual-action pain control. It was commonly prescribed for post-surgical pain, dental procedures, and minor injuries. While effective, the medication carried side effects such as dizziness, drowsiness, nausea, and constipation, along with the risk of dependence or misuse. Research later revealed that propoxyphene could cause serious heart rhythm complications, leading to Darvocet 100 mg being withdrawn from the U.S. market in 2010. Patients are encouraged to seek safe, medically approved alternatives for pain management.
