Neurologist prescribed it.
It may possibly be that he is familiar with it and wanted to start with it, ie. he has been working in the field for a long time.
I didn't select it. He wanted to start with this before moving on to any other meds, and I may be ignorant, but from what I have read, the oral meds are generally moved to last, for whatever reason.
Are the other meds actually better, or just a more preferred method of administration?
