My friend gave it to me saying it was x, but I know it's not because it long, blue, oval, and have a sort of "shinny" coat. There are also no markings on it? What could it be?
If it looks like the pill on the right I would wait until I could get ahold of a red pill instead On a serious note, it could literally be almost anything in the world. If it's not an official pill, and someone here doesn't recognize it god only knows. Try an E-Test kit?
Is it thin? Allegra, well that would be my guess. I have a full bottle sitting right here, but they have markings on it.
