Self-administered Intravaginal 2% Lidocaine Gel Prior to Intrauterine Device Insertion in Nulliparous Women: a Randomized Controlled Trial
Self-administered Intravaginal 2% Lidocaine Gel Prior to Intrauterine Device Insertion in Nulliparous Women: a Randomized Controlled Trial
This study is designed to evaluate if self-inserted intravaginal 2% lidocaine gel is effective at decreasing pain during intrauterine device insertion in nulliparous women.
Intrauterine devices (IUDs) are among the most effective forms of reversible contraception. Numerous studies demonstrate their safety and efficacy in nulliparous women, however, uptake of IUDs in this group is low. One of the major barriers to women obtaining IUDs is fear of pain during insertion, as studies do demonstrate that nulliparous women experience more pain than parous women during IUD insertion. Studies evaluating various methods for pain control during IUD insertion have shown conflicting results, leaving the question unanswered as to what is the best method to decrease pain during IUD insertion.
This study aims to evaluate a novel approach to pain control by having women self-insert lidocaine gel into the vagina at least 5 minutes prior to IUD insertion. This will overcome some of the barriers from other studies where there may not have been ample time for the lidocaine to take effect, while at the same time eliminating the need for women to have multiple speculum exams. Although this is a novel approach to administering an anesthetic, we believe women will be interested in any intervention that may potentially alleviate pain during IUD insertion.
If this study does demonstrate that pain is decreased with self-inserted lidocaine compared to placebo gel, this will potentially eliminate one large barrier to nulliparous women receiving IUDs. Increased uptake of highly effective contraception in nulliparous women is just one of the many steps necessary towards decreasing unintended pregnancy.
