Hi, I Am Just Trying To Find An Image Of

Hi, I am just trying to find an image of a discontinued drug that my mother took years ago for seizures. I believe that it may have been Phelantin but I'm not sure. I know that it was a small capsule that was like a clearish yellow that had a redish orange ring around the center. How can I find an image of this or know that this capsule as in fact Phelantin? Thank you
