Had to stop my current AA, not sure just how to differentiate between the two options my doctor gave me? So I was on Spiro, but I got another med (nonHRT) that does not play nice with most other meds. 

After an incident with my sodium levels crashing my doc told me to stop taking the Spiro. When I asked her what she planned on replacing it with and she said Finasteride or progesterone. I’ve done some reading on both these and I’m still a bit unclear if one is better than the other?

Any advice would be greatly appreciated, thanks!
