Viagra and airport security?

This could be a dumb question, but I was wondering, would it be a problem if I put generic Viagra from AllDayChemist in my checked baggage (domestic flight, not international)? It got through customs to get in the US, but just wondering what you all thought.

Bumping an old topic. As it turned out, it wasn't an issue for me. Just because I'm paranoid though, I put them in a vitamin bottle.
