"pay attention to the dose for researching those who have experienced negative side effects. many (although not all) of those with those unfortunate experiences started out at high doses (100mg+) 

my experience has been nothing short of a miracle. **brief history* i have suffered horribly with acne since the age of 15. i am now 42. i have tried everything from toothpaste tricks to antibacterial drugs (bactrim) to proactive. nothing worked. not even yaz. i was a mess. i would break out viciously with each cycle and have different stages of old &amp; new acne. this stopped it in one week. 25 mg, twice daily- zero side effects. do it at this dose &amp; you might get the same results!!"
