Outcomes

Primary Outcome Measures

Maximum Pain Score Over Study Period
reported on an 11-point numerical rating scale (NRS 0-10) where 0 indicates no pain and 10 indicates the most severe pain

Secondary Outcome Measures

Number of Ibuprofen 800mg Tablets Used
summed number of tablets used by each participant over the 72 hour study period
Number of Oxycodone/Acetominophen Tablets (5/325mg) Used
summed number of tablets used by each participant over the 72 hour study period
Number of Participants Ever Experiencing Different Symptoms During Abortion
A participant was included once if they ever reported a symptom during the 72 hour study period, not reflective of how long the symptom lasted. These were all commonly reported side effects during previous research on medication abortions and commonly reported side effects of pregabalin, so they were not included as adverse events.

5. Study Description

Brief Summary
Medical abortion has been associated with significant pain. The objective of this trial is to determine whether one dose of pregabalin 300 mg, given during medical abortion in addition to the standard of care analgesics, will decrease experienced pain. Investigators will perform a randomized, double-blinded, placebo-controlled trial. Participant pain levels and side effects will be assessed at multiple time points, along with a measure of satisfaction.
