The pill is white and round, on one side there are no numbers or letters, only lines to split it in half. On the other side the split lines are not visible; however, there are the numbers 93 on top and then 54 on the bottom. It is from US and I may have picked it up in either Denver CO or Harrisburg region Pa. I have them in a bottle labeled for tramadol, but I don't remember if it is tramadol or promethazine.
