I was diagnosed with AFIB in June by my PPP. After seeing a nurse practitioner (who I thought was a cardiologist- which I asked for!), she put me on Losartan, Levothyroxiine, Metoprolol, Furosemide, and Eliquis!!! I swelled up like a balloon. So they put me on a water pill, Lasix which didn't help much. I had been taking Triemterine for my BP which worked very well for me and it is also a water pill. So they switched me to that pill. . . which didn't help much either. So I increased the dosage by 1/2 pill in a.m. and p.m. I got into BIG trouble!! My kidneys developed a type of poison called "carenitine" sp? I spent 10 days in the hospital trying to clear my kidneys up!!! Now I've been told instead of AFIB, I have a "quiver" heart beat. I will address this to my cardiologist's next visit. Has any one else had the same reaction (swelling) when using these meds? Thanks and God bless!
