Extended use of the Multiload Cu-250.

To evaluate the safety and effectiveness of using the Multiload 250 (MLCu250) beyond its recommended maximum use time of three years, two groups of MLCu250 users were evaluated; one group had used their IUDs for less than three years and the other group had used their IUDs from 3 to 9 years. Except for pelvic infections, there were no significant differences between the two groups in IUD event rates or the incidence of complications. All pelvic infections in the long-term user group were mild and did not necessitate IUD removal.
