I found half a pink pill in my childs bathroom after some friends stayed over for the weekend. The pill looks like it was oval shaped and is pinkish/peach in color and white on the inside. The imprint is SAN on one side and 25 on the opposite side. I think it is from SANDOZ but I am not sure about what the opposite side is so I can't look it up. Does anyone know what this could be. I'm worried about my son.
