Recently my best friend called me and found a roundish blue pill in her boyfriends pocket with either 100 or 400 on it and she doesn't know what is it. If anyone out there can tell me what is it or what they think it is I would greatly appreciate it. Thanks :confused:

Any pill that has been 'found' should be disposed of immediately.

Is his pill scored?? Meaning... is there a line in the middle of it like where you could break it in half?

If the only marking was "100" then it is almost certainly Amoxapine, a depression medicine, I can't find any blue pill with only "400" as the marking.

Again unless you can be sure it was 100 on one side and nothing on the other this isn't for sure. She should just ask him
