IMHO....they're just covering their rear ends. Something to document in your medical records stating that they did encourage you to continue on Ty just in case you do end up with a bad exacerbation. It's in black and white that they tried to get you to take it.
My Neuro is doing the same thing. Putting the statement "patient refuses to take DMD's" in my records numerous times. I told him that the low percentage rate for
possibly reducing the duration of an exacerbation is just not good enough for me to keep putting that poison in my body. Of course, that statement is nowhere to be found in my records.
