Both my cardiologist and my nephrologist have recommended Jardiance. I do have kidney failure, and I also have diastolic heart failure. I have not yet taken it because of the cost and because of the side effects. It is helpful for me to read others here who have taken Jardiance and it has helped their conditions. Because I have a Part D Medicare drug plan, I am unfortunately not able to get any discount cards for Jardiance. Also - my Xarelto has tripled in price - again no discount programs are available to me. I just may have to "bite the bullet" since I need these drugs. A relative gets her Eliquis from Canada; I may go that route.
