Thank you so much for the answer. You have put my mind at ease. The truth is that when I dropped my step-son off at school this morning, this pill rolled out of his pocket. I was so frightened to think that he was taking drugs. After reading your information, I told my husband about what I had found and your answer, he told me that the childs mother gave it to him to help with his acne. So much for communication in my household. Thank you again. I know that I will sleep well tonight.
