Pill Identification RDY 22|1?

Does anyone know what a round pill with RDY on one side and 22|1 on the other side is?

Thanks
Update: It's like a peach kind of color, my daughter is on lamotrigine and it usually does not look like this and I am worried it is the wrong medication because she has had sever different generics of it and they never looked like this one.
