I Am Taking Cardizen And Eliquis Now For My Heart

I am taking cardizen and eliquis now for my heart rate. been on this since 4/27. I eat before taking my meds so that has stopped the headaches in the mornings but I have a cough and prior to this last incidenti with AFIB on 4/25 I had been to another dr. 3 times for strep throat. I am wondering what is causing this dry hacking cough and would LOVE to get rid of it.
