I found this pill in my medicine cabinet and was wondering what it is. It's a round pill, white/off white, on one side it's scored with an F on one half side and a D on the other. On the second side of the pill are the numbers 602. Can you tell me what it is. Thank You ## Hi Debbie. After trying several variations of "FD 602" I haven't been able to locate a match in any of the prescription drug databases. Just a thought, but it could be an over the counter medication, as OTC meds aren't required to be listed in the drug databases. I would consider taking the pill over to your local pharmacy and having it analyzed by their team to see what they come up with. Unfortunately, there's not much else you can do except take it to a lab and have it tested for ingredie...
