Ibuprofen prophylaxis for levonorgestrel-releasing intrauterine system insertion: a randomized controlled trial

BackgroundDespite the high efficacy of the levonorgestrel-releasing intrauterine system (LNG-IUS) in preventing pregnancy, uptake of the intrauterine devices remains low in the United States. Decreasing pain at the time of intrauterine device insertion may be one way to increase interest in this method of contraception.Study DesignWe conducted a double-blind, placebo-controlled trial, randomizing women to 800 mg ibuprofen or placebo 45 min prior to LNG-IUS insertion to determine effect of ibuprofen on the pain of LNG-IUS insertion.ResultsEighty-one women completed the study: 44 received ibuprofen, and 37 received placebo. Women in the ibuprofen and placebo groups had similar mean scores for anticipated pain (4.07 and 3.91, respectively; p=.79), pain with tenaculum placement (3.86 and 3.81, respectively; p=.90) and pain with insertion (3.69 and 3.34, respectively; p=.91).ConclusionAdministration of ibuprofen prophylaxis for LNG-IUS insertion does not decrease pain at the time of insertion.
