"i went on kariva because i was told that it helped with acne along with being an effective birth control method. i&#039;ve tried several other birth controls (including nuvaring, tri-sprintec, etc.) and had very intense side effects from them. i finally happened upon this miracle that evened out my mood swings, gave me a shorter lighter period and gave me clearer skin than i&#039;ve had in 10 years. i have zero complaints about this medicine."
