The objectives of this study were to evaluate the acceptability of the LNG-IUS Mirena(R), when offered as an additional option in a free choice context, and to evaluate the possibility of using this method in women with increased bleeding wanting an IUD and in copper IUD users requesting removal of the device for bleeding problems. A total of 256 women chose Mirena and were accepted into the study during the enrollment period. This represents 23.3% of all new acceptors of contraceptive methods in the clinic during the same period. Discontinuations were fairly evenly distributed among expulsion, bleeding changes, pain, and personal reasons. Bleeding changes were decreased bleeding, oligomenorrhea or amenorrhea. Comparing the performance in the group of women who chose the LNG-IUS as a first option with those having heavy bleeding, the only difference found was a higher expulsion rate in the group with bleeding problems. No pregnancies occurred and continuation rate was slightly over 75% in the total sample and in both groups. The characteristics of the LNG-IUS (Mirena) allow predicting that this method can effectively contribute to the increase in contraceptive options when introduced to family planning programs in Brazil.
