Summary

This trial seeks to investigate if using gabapentin as part of post-op care helps reduce pain from minimally invasive surgery for prolapse.

Who is the study for?
This trial is for patients with different types of pelvic organ prolapse who are undergoing minimally invasive sacrocolpopexy. It's not for those currently on gabapentin or pregabalin, dependent on oxygen, with renal failure, or using daily narcotics for over two months.
What is being tested?
The study tests if Gabapentin can help manage pain after minimally invasive surgery to correct pelvic organ prolapse. Patients will either receive Gabapentin or a placebo to see which is more effective in reducing post-operative pain.
What are the potential side effects?
Gabapentin may cause side effects like dizziness, fatigue, visual changes and swelling in the extremities. Some people might also experience gastrointestinal issues such as diarrhea or constipation.
