[jacksully]

I have a round baby blue pill with the imprint I3 on one side and the other side is blank. anybody know what this is?

This is new and not in the database yet, I've seen it at work, but the label was ripped off the bag, I think it was white/oblong though, it would have to have been OTC, I figured it was Ibuprofen 200mg, but I doubt yours being round and blue, I think it would more likely be Naproxin.
If I think about it tomorrow I'll ask around at work, otherwise we'll have to wait for someone to come forward or the databases updated.
