There's probably a blood test that can reveal the recent use of Viagra, but you can be sure that a pre-employment screening won't be looking for it, simply because it isn't illegal. Employment drug screening doesn't go on a general witch-hunt to see what they can find. They test for evidence of use of a few specific illegal drugs, and that's it. They won't discover anything that they're not testing for. Actual experience: I was once on several prescription drugs at the time of a pre-employment drug screening, and I brought along a list of my prescriptions to attach to my blood sample, to explain anything the lab might 'wonder' about. The response was: "Oh they don't look for any of those.", and they wouldn't even keep the list. One of my prescriptions was related to a substance that's often abused, so I was concerned. But I passed, without any questions, comments, or feedback. So don't worry. Just keep it up.
