The pill I have is oval shaped but the sides are squared off. So if you look at the pill from the top, it looks oval/oblong, but if you look at the sides, it's kind of square. It has a capital N on one side and 375 on the other side. I think it might be an extended-release Naproxen Sodium, but I'm not sure. It ended up in the wrong pill bottle somehow, and I don't remember what it is. Can someone help me with this? Thanks!
