I HATE PLASTIC OPANAS!!! I have a prescription for 20 mg opana ERs, and am drastically desiring to obtain its generic version. The "G 73" tablets work better for me and are much more inexpensive. The doctor has checked the "product selection permitted" box at the bottom of the prescription, which I thought would allow me to receive a generic version of the medication prescribed, unless of course the doctor writes "brand name medically necessary" on the script, but I am still having a problem. A friend in a similar situation told me he thinks that the doctor must write the prescription for "oxymorphone", not "Opana" in order to receive it in a generic version. Is this true? Please someone who knows advise me, because as my topic indicates, "I hate the plastic opanas!"
