The Effectiveness of Topical Prilocaine-Lidocaine Cream Plus Acetaminophen and Naproxen Compared to Lidocaine Injection Plus Acetaminophen and Naproxen to Manage Pain During IntraUterine Device Insertion

Summary

The goal of this clinical trial is to learn if two pain medications used to treat pain during intrauterine device insertions work in persons with a uterus. It will also learn about the safety of the two study medications. The main questions it aims to answer are: Does prilocaine lidocaine, acetaminophen and naproxen or lidocaine injection, acetaminophen and naproxen reduce pain during intrauterine device insertions. Researchers will compare prilocaine lidocaine cream and lidocaine injection to see if it treats pain during an intrauterine device insertion. Participants will be asked to: * take acetaminophen and naproxen prior to the procedure. * receive either prilocaine-lidocaine or lidocaine injection during the procedure * to fill out a survey on past medical history, anxiety, and pain.
