This is a very tiny white pill, slightly bigger tall then it is round, it almost resembles a sweetner or something, I used a magnifying glass to check for markings and could not see any, possibly a 10 on one side. It does have a coating on it. I put tape over it on a piece of paper and where the tape touched the pill (which I had broken the coating slightly to make sure it was a pill), that area turned pink. I am hoping it is not some kind of poison.
