Question of the Month
I was prescribed 100mg of Aldactone per day by my dermatologist, to treat acne,
but I've been doing some research since and I realized that it can actually
worsen your testosterone level (cause facial hair, deeper voice etc.) How can an
anti-androgenic drug have this adverse effect and am I in danger of having these
unwanted effects with my dosage? Thanks for answering me, I am really worried...
I am frequently asked questions similar to this
one. Spironolactone (Aldactone) does not have testosterone-like effects. This
medication has been around a long time and there is much misinformation about
it, even on the official package insert. I'm not sure how all this got put there
but it is from a long time ago when methods of clinical research were much less
refined than they are now.
With problems related to excessive testosterone effect spiro can only help, it
will not make them worse. As with any medication, it does not work as well for
everybody. Usually however, it does help. It does work slowly so the problem,
especially alopecia, may get worse before the medication starts to work.
Spiro can cause mild dehydration due to increased salt and water loss. This can
almost always be prevented by drinking plenty of water. Some need to increase
salt intake but this needs to be discussed with your doctor.
Spiro sometimes makes periods come closer together but this can be prevented by
taking it with birth control pills - again, something to discuss with your
Spiro may work best when combined with other medications, especially when the
testosterone level is high. Of course, as with any medication which blocks
testosterone, it is essential not to be taking it if pregnant. Effective
contraception is a must.
Just to repeat: spironlactone will not make acne, increased hair growth or
Hope this is helpful.
