It is a round(circle) pill with the imprint R 1 5 0 going across the top against the rim of the pill. The back side of the pill is blank. It's a light faded type of orange that looks kind of pink- peachy colored. I found it in the back of my car after new years and I would like to know what this is. If it's possible to post a picture so I can make sure of what it is that would help so much, Thanks!
