Ok so my dermatologist decided to put me on 100mg of this a day to control acne breakouts. At first it worked really well, and it has kept the acne from flaring up on my face to one or two pimples every few weeks, however two days ago I woke up with tiny little bumps on my chest and shoulders that looked like heat rash, then they turned into tiny pimples, when i pop them they turn into another full white head within an hour. Has anyone else been on this med and have this happen to them...I'm going to follow up with the doc but he is booked for a week and was just hoping to get a little piece of mind until then. Thanks.
