After taking Norco 10-325 for six weeks after tibial plateau surgery, I had to get my prescription filled at a different pharmacy and they gave me Lorcet 10-325. It seems to be affecting my stomach whereas the Norco did not. What's the difference?
From my research, they are identical... HOWEVER!
There may be something in the medication, a binder, the colorant, like that, that your body doesn't like.
Try taking it with food, or milk, to buffer the stomach.
