Sublingual Misoprostol Prior to IUD Insertion in Women with only Previous Caesarian Section: A Randomized Controlled trial

Abstract

Intrauterine Devices (IUDs) are widely used as reversible contraceptives. Both copper- and Levonorgestrel-releasing IUDs (LNG-IUDs) are safe, costeffective in the long term and equally effective. However, a disadvantage in nulliparous women is that the insertion of an IUD through a narrow cervix may be clinically difficult and painful. By transvaginal ultrasound the cervix of women with a previous elective caesarean section may resemble the cervix of nulliparous women. In an attempt to facilitate IUD insertion for nulliparous women, off-label use of misoprostol has been promoted by several sources.
