Study description

This is a pre-post, observational study using data derived from existing healthcare databases to answer the research question whether the newly implemented risk minimization measures for topiramate are associated with change in topiramate use and pregnancy exposure to the drug among women of childbearing potential with epilepsy or migraine diagnosis.
The study aims to describe the prevalence and the incidence of topiramate use among women of child-bearing potential (WOCBP) with epilepsy or migraine during the pre- and post-implementation period of the newly implemented risk minimization measures (RMMs).
In addition, the study aims to quantify exposure to topiramate during pregnancy among incident users of topiramate at two critical points:
(1) being pregnant at treatment initiation, and
(2) becoming pregnant during treatment.
