My recommendation is to talk with your cardiologist. Maybe print out some articles on it, and tell him your concerns. He wants you alive - believe me!

My primary care physician is the one who prescribed it.
I have thought about calling him, but am afraid I would need an appointment.
Quite frankly, I don’t want to go to a doctor’s office unless I have an emergency.
