Generic antiepileptic drug prescribing: A cross-sectional study

► Patient populations getting brand and generic antiepileptic drugs (AEDs) are varied. ► Older patients have statistically increased odds of receiving a generic AED. ► Patients on Medicaid have 2.44 times the odds of receiving a generic AED. ► Insurance plan and region of residence influence the odds of getting a generic AED. ► These differences represent important confounders for future studies in the field.
