I AM A DIALYSIS PATIENT. I Am Having Trouble Get

I AM A DIALYSIS PATIENT. i am having trouble get my potassium down. I am doing my best to eat the right foods. I have been taking kaxalate on none dialysis days. However, it is still 5.4. I take a lot of blood pressure pills. I was noticing that Losartan talks about potassium. Does it actually have potassium in it. I have checked a lot of foods and almost all of them have some form of potassium. So seems like I cannot win for losing. I just would like some more input.
