I found a batch of these unidentifed tablets. They are white, oval-shaped, flat pills. They are scored down the middle with the capital letter 'M' on one side of the scoring and '125' on the other side of the scoring. The reverse side of the pills are blank.
These pills may be Glyburide 3mg (generic for Glynase Press-Tab) by Mylan.
Imprint: M 125
Description: Lt. Yellow, Scored, Oval
They are actually described as light yellow - there is an image on the Mylan website at mylan.com if you want to take a look and see if they match up.
Yep. That's what they are. I checked the Mylan Web site, and their sample of the 3mg dose looks white to me, just like the pills I have. In any case, I know what I'm looking at now.
