I guess it would depend on the situation. If you were going through a record OP. Since stadol is used primarly for migraines and headaches and hydro can be used for a number of things if you records to show the need to back both of them up, the probabaly would prescibe both. Skyrx has stadol and since they are a no record OP I don't know if they would let you order both at one time, but you may order at different times.
