Darvocet 100mg typically referred to a formulation containing 100 mg of propoxyphene napsylate and 650 mg of acetaminophen. It was a combination medication used for the relief of mild to moderate pain. However, Darvocet was withdrawn from the market due to safety concerns related to propoxyphene, including the risk of serious cardiac arrhythmias. As a result, it is no longer available for use. If you are in need of pain relief, it’s best to consult with a healthcare professional for alternative medications or treatments.
