What this trial studies

This clinical trial evaluates the effectiveness of non-steroidal anti-inflammatory drugs (NSAIDs) for pain management during medical abortion procedures for pregnancies between 13 and 22 weeks. Participants will be divided into two groups: one receiving NSAIDs prophylactically and the other receiving them on-demand as pain occurs. The study aims to determine if the prophylactic approach leads to better pain relief outcomes and to assess any potential adverse effects associated with NSAID use in this context. Pain levels will be monitored using validated scales throughout the procedure.

Who should consider this trial

Good fit: Ideal candidates are pregnant women aged 18 and older, between 13 and 22 weeks of gestation, who are seeking a medical abortion.

Not a fit: Patients with contraindications to medical abortion or those with certain medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective pain management strategy for women undergoing medical abortion.

How similar studies have performed: Previous studies have shown varying success with NSAIDs in pain management, but this specific approach in the context of medical abortion is less explored.
