I have a Capsule, One side is white, the other side is green.. The Green part has a lower case e that looks like it is 3 lower cases e's drawn a little offset from each other (Like if you held 3 pens in your hand and wrote a lower case e in one swoop - they are all spaced). The white part of the capsule has "506" and if you roll the capsule it says "60 mg" on the other side. Thanks

I appreciate your help with the id... Just curious- which database did you use to find out what this was? ... Or did you just know off hand? Thanks again.

I use this one the most: http://www.wallsrx.com/services/cpident.cfm , but if you look to the upper left of this site ,under Resources for Pill Identification, you'll find a pretty good list to choose from.
