Off the market: Hello. Darvon (50mg of propoxyphene) and Darvocet N-100 (100mg of propoxyphene) were taken off the US market at the end of 2010. If you have any of these left over from 2010, you shouldn't take them. They need to placed in a ziplock bag filled with water. Then discard in the trash. Otherwise, if your police department has a drop box, then discard these pills there.
