I'm a bit concerned about this, too. I'm on a pretty low does of estradiol and low dose of spironolactone. I just found out my doctor is planning on keeping me on this dosage until next year, regardless of the labs! I'm thinking very hard on going with a new doc. She also, before she prescribed me spironolactone, was concerned that spiro and finasteride my conflict with each other. I guess this should've been my first warning.
