Glimepiride

I have a generic tablet of Glimepride furnished by Liberty Medical. The tablet is oval in shape in a light green color. The tablet on one side shows RDY and the other side 3/21. This tablet can be cut in two. I need to verify this if indeed it is the right tablet for me to take because it was not authorized by me or my doctor to be sent in the mail. I would like to know who the manufacturer is and any other information, e.g if this is two MG and if it is really a generic form of Amaryl. Any information that you can tell be about this will be greatly appreciated.

Thank you,

Don Korwan
