First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two pain management methods for IUD insertion: a numbing cream plus pain pills versus a lidocaine injection plus pain pills. About 66 people with a uterus who want an IUD for birth control will take part. The goal is to see which approach works better and is safer for reducing pain during the procedure.
