About

The objective of this study is to determine if a synthetic cannabis derivative, dronabinol, in addition to ibuprofen, decreases maximum pain scores compared to ibuprofen and placebo in women undergoing medical abortion. Results of this study will help providers counsel patients regarding cannabis use during medical abortion.

Full description

This is a randomized, double-blind, placebo-controlled trial comparing pain levels in women undergoing medical abortion with one of two regimens: ibuprofen 800mg and a 5mg oral dronabinol versus ibuprofen 800mg and placebo given at the time of misoprostol administration. This study will include 62 women undergoing medical abortion. Women will be randomized to dronabinol 5mg oral versus placebo. The primary outcome will be maximum reported pain score within 24 hours of misoprostol administration.
