Levonorgestrel-releasing intrauterine device in the treatment of menorrhagia.

In 20 women with menorrhagia (greater than 80 ml blood loss per menstrual period) a levonorgestrel-releasing intrauterine device (Lng-IUCD) was inserted. Menstrual blood loss (MBL) was measured in two consecutive cycles before the device was inserted and after 3, 6 and 12 months of use. MBL was significantly reduced after 3 months (86%) and after 12 months the reduction was 97%. There was a significant increase (P less than 0.001) in serum ferritin during the first year of Lng-IUCD use. The Lng-IUCD seems to be an important alternative to oral medication and to hysterectomy in the treatment of menorrhagia.
