Misoprostol Prior to Intrauterine Device (IUD) Insertion in Nulliparous Women (miso)

January 10, 2018 updated by: Eva Lathrop, MD, Emory University

A Randomized Control Trial of Misoprostol Versus Placebo for Cervical Priming in Intrauterine Device Insertion for Nulliparous Women

Because of misoprostol's known ability to cause cervical dilation, some family planning providers give their patients a dose of this drug prior to insertion. The goal of this study is to evaluate whether misoprostol prior to IUD insertion in nulliparous women eases insertion and decreases pain.

Detailed Description

There are currently 2 intrauterine devices (IUDs) available in the U.S., the copper T380 (paragard) and levonorgestrel IUD (Mirena). The effectiveness of IUDs is very similar to tubal sterilization[1], with an overall unintended pregnancy rate of less than 1% in the first year, and lower failure rates in subsequent years. The cervix of a nulliparous woman has a smaller diameter and can lead to more difficult and uncomfortable IUD insertions. Because of misoprostol's known ability to cause cervical dilation, some family planning providers give their patients a dose of this drug prior to insertion. The goal of this study is to evaluate whether misoprostol prior to IUD insertion in nulliparous women eases insertion and decreases pain. The null hypothesis is that misoprostol does not influence difficulty of insertion or patient perception of pain. The primary outcome is the ability to insert the IUD without dilation of the cervix or using ultrasound for guidance.
