I was on this antibiotic for 1 year 2 months!
First few months where great, my skin had dramatically cleared up, i would have at least one new whitehead everyday.. but such an improvement.
Gradually after about 3 months of being on this med, my skin adjusted to the antibiotic and got worse and worse, a year and 2 months had passed and my skin was back to square one, just as bad as when i had started except now it had spread all around my face, nose, chin, forehead, and where it was originally, around my mouth and smile lines..
I would recommend it if you are looking for a quick fix, but for a lasting cure, no chance, i'm currently on another antibiotic, waiting for accutane..
