"i&#039;m a 28 year old woman who switched from oral birth control to the mirena iud.  that is the only change i can associate with a horrible bought of hormonal acne that started about 6 months after i made the switch.  i had embarrassing, painful acne along my jawline down onto my neck.  my skin was greasier than normal and products that would typically keep my breakouts at bay didn&#039;t touch the cysts on my jawline and neck.  i&#039;ve been taking 100mg of sprio for about 6 weeks now and i&#039;ve already seen great improvement.  my skin isn&#039;t 100% yet but it&#039;s obviously improving and i assume it will get even better with time.  i haven&#039;t experienced any side effects, no weight gain, dizziness, or breakout period."
