About this trial
The aim of this study is to determine if 5g of self-administered topical 2.5% lidocaine/2.5% prilocaine cream, reduces pain during IUD insertion and/or endometrial biopsy. The proposed study is a double-blind, placebo-controlled RCT. Each participant will be randomly assigned to one of two arms: 1) Intervention (5g of 2.5% lidocaine/2.5% prilocaine cream in a pre-filled vaginal applicator). 2) Placebo (5g of VersaPro cream in a pre-filled vaginal applicator). Participants will be asked to self-administer the pre-filled vaginal applicator at least 10-15 minutes prior to the procedure. The patient will be asked to rate their pain throughout various steps of the procedure and complete a post-procedure survey afterwards. The primary outcome is global pain score, which will be patient-reported by the 100 mm Visual Analogue Scale (VAS) 5-minutes following the procedure (endometrial biopsy or IUD insertion).
