Joseph,
You're kidding? They make you write the name of the pharmacy? What is the difference between that, and the fact that the pharmacy's fax number is on the top of the page?
That seems crazy.
So, does this mean if some hacker can fax from home and make it look like it came from your office, their putting the pharmacy name on it will stop them? Wouldn't they know what pharmacy it is going to?
Now, putting the name on a script which you hand to the patient makes much more sense.
