We have talked about what is called step therapy on the show before. It's when your insurance company requires you to try a less expensive version of the drug your doctor has prescribed you to see if it works just as well. If it does not, then you will be able to use the drug that was originally prescribed. This is also called step therapy, and some would like to see it change. Advocates were at the state Capitol calling for the practice to be modified. They don't want step therapy eliminated but they do think the choice should be up to the doctor instead of the insurance company. Doctor Nilay Shah, a neurologist, joins us to talk more about it.
