The European Active Surveillance Study on OC Prescribing Practice, Benefits and Safety (EURAS)
In Brief
An observational study evaluating Drospirenone, Levonorgestrel, and 1 other intervention for Contraception. Completed, enrolled 59,510 participants across 1 site.
Detailed Summary
EURAS is a multi-national, controlled, prospective, post-marketing, non-intervention cohort study of new users of drospirenone/ethinylestradiol (DRSP/EE), levonorgestrel/ethinylestradiol (LNG/EE) and other oral contraceptives (OCs) under routine conditions of medical practice in seven European countries. Baseline survey and semiannual, active follow-up are based on postal questionnaires, with validation of reported events by the women's treating physicians. A multifaceted 4-level follow-up procedure will be established to ensure low loss to follow-up rates. The objective of the study is the investigation of the incidence of rare serious adverse events associated with the use of new and established OCs, and specifically the incidence of thromboembolic events.
