Square Blue Pill with Round Corners and "A" Imprint

[Granulado]

I found this pill on the ground at my apartment in southeast Michigan.

Front:



Back:



The pill is light blue in color, square with round edges. It has a capital "A" imprint on the front and no imprint on the back. Any idea as to what it might be? I am not familiar with the stylized A imprint on the pill.

[Granulado]

Never mind, it's an altoid mint. *facepalm*
