Can some one tell me about how mineria works and its known side effects and possibly how long it has been out
Answers: Mirena will change your menstrual cycle and eventually make your periods much lighter. However, in the first three months of use, many women experience unpredictable bleeding, and about 20 percent have prolonged periods that last more than 8 days. After three months bleeding becomes more regular and may stop altogether. In studies of Mirena, women's periods were reduced by 85 percent after three months and 97 percent after a year. Although bleeding is much lighter, some women who use Mirena have difficulty predicting when their period will occur.
Beyond these menstrual irregularities, Mirena has few side effects because it contains such a small amount of hormone. Some women do experience mild side effects related to the hormones such as headaches, water retention, breast tenderness or acne. Often these resolve after the first two months of use.
