Spironolactone
"I'm a 25 year old female and I suffered terrible acne for a long time, then it went away for a few years. Suddenly back in September 2016 I started to break out again in those painful cysts around my jawline, where I had never broke out before. Spiro helped me many years before so I started taking it again. First week 25 mg and then 50 mg. Had the notorious "Initial Breakout" but after that cleared up (took 2 months) I've been good ever since! It's nice not waking up each morning to find new painful cysts under my chin! Love it. It has caused some dizziness but I'll take that over a pimply, painful face any day. Be patient, this drug takes a while. Worth it though."
