Spironolactone
"I have to say after all the other medicines I've tried I'm not sure why this was the last resort. This was the only medicine that worked for my cystic acne caused by my PCOS. I've tried birth control antibiotics topical treatments you name it. Nothing beside this has really worked for me I a on 100 mg once a day and this has been my savior. Although i found it took a good month to see oil reduction. Only con was irregular periods but after 5 months it straightened out."
