Switching and discontinuation of participant-masked randomization to a copper or levonorgestrel intrauterine device when presenting for emergency contraception.

ABSTRACT:

Objectives

Examine intrauterine device (IUD) switching or discontinuation up to 6 months after participant-masked randomization to different IUDs.

Study design

Participants were randomized 1:1 to the copper T380A or levonorgestrel 52 mg IUD for emergency contraception and informed they could switch IUD type without cost at any time.

Results

Of the 327 subjects allocated to the levonorgestrel IUD, 7 (2.1%) switched their IUD type by 6 months versus 18 (5.5%) of the 328 copper IUD users (RR: 0.4 [95% CI: 0.2, 0.9], p = 0.03). Six-month IUD discontinuation occurred in 34 (10.4%) levonorgestrel and 35 (10.7%) copper IUD users.

Conclusion

Individuals randomly assigned to IUD type at presentation for emergency contraception continue their assigned IUDs at high rates
