Lidocaine-prilocaine Cream as Analgesia for In-office Levator Muscle Trigger Point Injections

Levator muscle trigger point injections (TPI) are a commonly performed procedure in the office for treatment of pelvic pain related to pelvic floor muscles. The most common concern related to in-office TPI is pain. Currently, there is limited information about which medications could reduce pain during TPI. Pain control during in-office gynecologic procedures is a very important topic, and doctors are researching possible options for pain control during these procedures. Lidocaine-prilocaine cream is U.S Food and Drug Administration (FDA) approved for use on the genital area as pretreatment for procedures involving needles. The purpose of this study is to assess if vaginal lidocaine-prilocaine cream reduces pain with TPI compared to a placebo cream.
