your pill is generic darvocet N-100, a mix of
propoxyphene and
tylenol. A weak narcotic anelgesic, and a schedule IV controlled substance. BTW the M in a box is the logo for Mallinckrodt Pharma, not
MS contin. Some of their pills just have an M, some the M in a box, and they do make
morphine contin that bear that logo, but it's for the manufacturer not the drug.
