I've got a white capsule (-maybe- an oval) with SP (divider line) 39 imprinted on one side. I think it might be one of 2 things, either Tylenol with Codeine (some generic variation), or a generic ibuprofen of some kind. I found 2 of them in a sandwich bag in the back pocket of my college brother's jeans while doing the wash, but I'd like to know before I ask what it is just in case it is the Tylenol with Codeine and he's got some kind of problem.
