Please help identify. Xanax shape, blue L44I

[Debbiek38]

Could you please identify a pill I found at my fiance's house. I'm concerned because of a depression he's going through. It's blue and is shaped like a Xanax. It looks identical to a blue Xanax. One side just has a split down the center and the other has the numbers and letters L44l. I can't tell whether the last number is a 1 or a lower cased L. I really, really need to know what this is and it's pretty urgent due to his state of mind.

Thank You So Much.
