I was on it. I've never heard of it prescribed for OCD though... only for psychosis and/or mood stabilization. (Although it's a pretty new drug.) I had only mild success on it for mood stabilization. I am unsure as to how it works for OCD, though, since I wasn't really thinking about a potential relationship between it and my OCD.
On the upside, I don't remember any particularly bad side effects...
