Spironolactone
"Was prescribed this medication for hormonal acne and started at 100mg daily. This did nothing for me so at my 3 month check up the dermatologist switched me to 150mg daily. This immediately made a huge difference in my skin and within 2 weeks I noticed a reduction in breakouts. I used to break out a lot during my monthly cycle and now I get maybe 1 pimple a month. I also started using a Clarisonic brush to cleanse my skin better.  You have to be patient with this medication as not everyone reacts the same to the same dosage. You and your doctor may have to try different doses before you get it right but once you do it is worth the wait!"
