Hello,,, which medicine is most effective to stop periods among Lybrel, Seasonale or Mirena (levonorgestrel) IUD....which medicine is most effective and better???

Pills or IUD? To be effective, pills need to be taken daily, and there may be some interaction with other meds. If there are side effects, it is easier to stop taking pills. Mirena (levonorgestrel) IUD needs to be inserted/removed by a physician and gives protection up to 5 years. Lybrel is intended for consecutive 365 days but with Seasonale there are 4 periods a year. Your doctor can help you decide which is best for you.
