My husband talks Entresto (sacubitril/valsartan) twice a day.
I just heard on the news that valsartan has been known to cause cancer. He has been a heart patient for many years, by-pass,stents,
defibulator and pace maker. I know his dr. would not prescribe this medication if he didn't think my husband needed it. What's your
feelings about valsartan? Thank you.
