Study summary

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.

Read the 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.

What researchers measure

Primary outcomes

  1. Provider Perceived Ease of Insertion on a 100 Point Visual Analogue Scale

    The visual analogue scale for perceived ease ranges from 0 (most ease) to 100 (most difficult).

    Time frame: assessed immediately post IUD insertion

Secondary outcomes

  1. Patient Perceived Pain on a 100 Point Visual Analogue Scale

    The visual analogue scale for perceived patient pain ranges from 0 (no pain) to 100 (most pain).

    Time frame: immediately after insertion

  2. The Use of Adjunctive Measures Including Ultrasound Guidance or Cervical Dilation to Insert the IUD

    Time frame: assessed immediately after IUD insertion

  3. Time for Insertion Procedure

    Time frame: assessed immediately after IUD insertion

  4. Acceptability of Discomfort Associated With Insertion

    Time frame: assessed at one week after insertion and at one month after insertion

  5. Ease of Insertion and Presence of Pain in Nulliparous Women Versus Nulligravid Women

    Time frame: assessed immediately following insertion

  6. Need for Additional Pain Medications After Insertion of the IUD

    Time frame: assessed one week after insertion
