Darvocet 50 mg was a prescription painkiller combining propoxyphene, an opioid, with acetaminophen, a non-opioid analgesic. It was used to treat mild to moderate pain, including post-surgical discomfort, dental pain, and minor injuries. Common side effects included dizziness, drowsiness, nausea, and constipation. Studies later revealed that propoxyphene could lead to dangerous heart rhythm problems and increased risk of overdose. Because of these safety concerns, Darvocet 50 mg was withdrawn from the U.S. market and is no longer legally prescribed in many countries. Patients are encouraged to seek safer, approved alternatives under medical supervision
