"my nurse practitioner prescribed this for me for acne after i stopped using proactiv and my acne was the worst it had been in my life. it did help clear up my acne but i took these pills 2 times a day for over a year.... it did help my acne fairly well but i still broke out. the big problem i had though was the monthly yeast infections. i went back to my np at least 5 times and the times in between i just paid the $18 for over the counter meds for the infections. she gave me a couple different types of yeast infection meds and did tests each time to make sure it was a normal yeast infection but every month it would come back. i still suffer from them and its been 8 months off of that med."
