Abstract

Evidence-based guidelines on the management of pain associated with first-trimester medical abortion are lacking. Most published clinical trials have failed to report on this important aspect of the procedure. The aim of this comprehensive work was to provide clinical advice based on a comprehensive literature review, supplemented by the clinical experience of a group of European experts in case no evidence is available. Pain level ranged from 5 to 8 in 80% of studies where pain was measured on a 0-10 visual analogue scale; severe pain was reported by 20-80% of women. Pain assessment was rarely reported in studies. Pain treatment should be preventive and avoidance of unnecessary uterine contractions should be considered. Analgesic treatment should follow the WHO three-step ladder, starting with the use of NSAIDs and allowing for easily available back-up treatment with weak opioids.

Keywords: Pain; expert consensus; medical abortion.
