high blood pressure
"I took this medication for four years, all the while becoming less and less interested in sex and unable to achieve an erection. Having gone through 4 cardiologists not a one of them ever informed me that Aldactone is an anti-androgen which blocks muscle and bodily binding of testosterone necessary for it to take effect and also lowers production of testosterone itself. I had to happen upon it on my own. The day I found out is the day I stopped taking it. Giving a male a medicine which renders his testosterone ineffectual may be good for those undergoing a sex change but not for those who are not. There is another potassium sparing drug like Aldactone without the sexual side effects but it is more expensive. "
