Abstract
Objective: Anticipated pain with intrauterine device (IUD) insertion may be a barrier to widespread use. Our objective was to evaluate the efficacy of intracervical 2% lidocaine gel for pain relief with IUD insertion.
Study design: We performed a double-blind, randomized controlled trial of women undergoing IUD insertion. Participants were randomly assigned to 2% lidocaine or placebo gel. Study gel (3 mL) was placed 3 minutes prior to IUD insertion. Pain scores were measured at various time points using a 10-point visual analog scale.
Results: Of the 200 participants randomized, 199 completed the study. Pain scores among lidocaine and placebo arms were similar at tenaculum placement (lidocaine and placebo: median, 4; range, 0-10; P = .15) and with insertion (lidocaine: median, 5; range, 1-10; placebo: median, 6; range, 0-10; P = .16). These results did not differ by parity.
Conclusion: Topical or intracervical 2% lidocaine gel prior to IUD insertion does not decrease pain scores.
