I'm not sure if this is even the "name" of what I found in my son's drawer... it's just I can't seem to find any information on what I'm holding, so I'm hoping maybe you can help... this pill, is small, oval, yellow, and on the front there's just a "V" and on the back it's 36/01 or it's 38/01 can't tell... but can anyone tell me what this may be? Thanks Tanya
