I have been on minocycline now for about four months and would reccomend this product to others. I was perscribed this med in conjunction with differn gel (which i do not use) but have had success with just the minocycline. It took about two months for it to really start working so if you have just started, be patient. I still get occasional zits (mostly around the time of my cycle) but for the most part my skin has improved. I have not experienced any side effects (i take two pills before bed).
