Pain Medications Before IUD Placement

 

Am Fam Physician. 2020 Jan 15;101(2):119-120.

Clinical Question

Do preprocedure medications affect the pain of intrauterine device (IUD) insertion?

Evidence-Based Answer

Topical lidocaine preparations including gels, creams, and sprays may modestly decrease pain with tenaculum placement but not during IUD insertion. (Strength of Recommendation [SOR]: A, based on a meta-analysis of randomized controlled trials [RCTs].) The use of a paracervical block with unbuffered lidocaine does not decrease pain with either step. (SOR: A, based on a meta-analysis of RCTs.) However, a paracervical block using buffered lidocaine may decrease pain with uterine sounding and IUD placement, as well as overall pain. (SOR: B, based on an RCT.) Tramadol and naproxen decrease pain with IUD placement. (SOR: A, based on a meta-analysis of RCTs.)

Summary

A 2018 meta-analysis of 11 RCTs (N = 1,458) evaluated the effects of a paracervical lidocaine block or application of lidocaine to the genital mucosa before IUD insertion in nulliparous and parous women.1 Copper IUDs and the levonorgestrel-releasing intrauterine system (Mirena) were used. Pain was assessed using a 0- to 10-point visual analog scale, with higher numbers indicating more pain. A lidocaine preparation of 2.5% gel (three trials) or 2.5% cream (one trial), or a combination of 2.5% lidocaine and 2.5% prilocaine cream (two trials) was applied to the ectocervix, in the cervical canal, or both. Lidocaine 10% spray (two trials) was applied as four pumps (40 mg) to the ectocervix, and paracervical blocks (four trials) were performed as unbuffered 1% lidocaine injections on either side of the cervix and at the tenaculum site. Control interventions were placebo or no intervention. As a group, genital mucosa lidocaine applications reduced pain with tenaculum placement (six trials; n = 764; mean difference [MD] = −1.0; 95% CI, −1.9 to−0.09) compared with placebo or no intervention, but there was no significant difference with IUD insertion (seven trials; n = 828; MD = −1.0; 95% CI, −2.0 to 0.01).
