Is there something to counteract all the salt I'm consuming?

I have to have salt in my diet because of a medical condition I have and I'm supposed to get in twice the amount a normal person would. I can't cut down on it or I literally won't be able to function. Most of my salt intake is coming from salt tablets, so it's not like I'm pigging out on fries. I eat and drink very healthy, and get in lots of water a day. I can tell it's breaking me out, all on my face, and it's becoming very problematic for me. I take very good care of my skin. I know I'm reaching for straws here, but if there's something I can do about it, please let me know. Thanks in advance. :)
