I was on Accutane for 3 months, then followed up with this medication. I've been on it for almost a year, taking 100mg/day before bed. It helps, but you have to keep taking it to stay acne free. It also keeps yeast infections around for women. I would recommend it for normal acne, but not severe. My acne was cystic/severe. This is the second time in my life taking Accutane, first time Doxycycline.
