Topical Anesthetic for IUD Therapy
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a topical anesthetic cream (EMLA cream) to make IUD (intrauterine device) placement more comfortable for women. Participants will use one of two methods: applying the cream with a menstrual disc or a cervical cap before IUD insertion. The trial aims to determine which method better reduces pain during the procedure. It seeks women who have never given birth or had a pregnancy beyond 16 weeks, are generally healthy, and plan to have an IUD placed without sedation. As an unphased trial, this study offers a unique opportunity to contribute to research that could enhance comfort during IUD placement.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, if you are taking daily medication for chronic pelvic pain or have used oral anxiolysis, moderate/deep sedation, or narcotics in the past 24 hours, you may not be eligible to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that EMLA cream, a mix of prilocaine and lidocaine, is generally safe and effective for reducing pain during IUD insertion. Studies indicate that applying EMLA cream to the cervix (the lower part of the uterus) can decrease pain and make the procedure more comfortable. This cream has been used safely in many situations, with few reports of serious side effects.
In this trial, participants will apply EMLA cream using either a cervical cap or a menstrual disc before the IUD is placed. Previous research suggests that these methods are safe and effective for managing pain. The cream has been successfully used in other studies involving IUD insertions, supporting its safety. Participants in those studies did not report significant side effects, indicating that EMLA cream is a safe option for pain relief during IUD placements.12345Why are researchers excited about this trial?
Researchers are excited about these treatments because they offer a novel way to manage pain during IUD insertion using topical anesthetics. Unlike current pain management options, which might include oral pain relievers or numbing injections, these treatments use EMLA cream, a combination of prilocaine and lidocaine, delivered via a cervical cap or menstrual disc for targeted numbing. This method is non-invasive and allows the anesthetic to be applied directly to the cervix, potentially enhancing comfort and reducing anxiety associated with the procedure. The use of familiar, easy-to-use devices like a cervical cap or menstrual disc could make the process more accessible and less intimidating for patients.
What evidence suggests that this trial's treatments could be effective for IUD placement?
This trial will compare two methods of applying lidocaine-prilocaine cream to reduce pain during IUD insertion. Research has shown that lidocaine-prilocaine cream can reduce pain during IUD insertion, with studies indicating a decrease in pain by up to 28% during the procedure. Participants in this trial will receive either a cervical cap or a menstrual disc filled with the cream. Applying the cream to the skin numbs the area. Many patients report feeling no pain or less pain when the cream is used before the procedure. The cream is generally considered safe and effective for this purpose.25678

Are You a Good Fit for This Trial?
This trial is for generally healthy, English-speaking women who are scheduled to have an IUD placed at the Center for Women's Health in Complex Family Planning clinic without sedation. Participants must be able to review and sign study consents.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment

What Are the Treatments Tested in This Trial?
Interventions
- EMLA cream
Trial Overview
The study is testing two methods of applying a topical anesthetic before IUD insertion: using a menstrual disc or a cervical cap, each filled with EMLA cream. It's designed as an open label, double arm feasibility study with 24 nulliparous women divided into two groups.

Treatment groups
Experimental Treatment
Participants will be provided with a menstrual disc filled with 5mg of 2.5% prilocaine-2.5% lidocaine cream and manufacturer instructions for placement. Study personnel will leave the room, and participants will undress and attempt to place the disc. The provider will return to the room, make sure the disc is correctly placed, and set a seven minute timer. After the seven minute timer, participants will self-remove the disc or the clinician will remove it and place the intrauterine device (IUD) according to manufacturer technique.
