Lidocaine in IUD pain

Details and patient eligibility

About

Despite being the most common method of contraception, the use of intrauterine devices (IUDs) is limited by the associated pain during insertion. Many pharmacologic interventions had been studied for their efficacy to reduce IUD insertion pain, of them, lidocaine was found to be superior over NSAIDs or other local anesthetics. This work aims at comparing the safety and efficacy of different lidocaine formulations to optimize selection in reduction of IUD associated pain.
