Objectives The purpose of this study was to investigate whether prescribed antiepileptic drugs ( AED s) were consistent with what patients actually used, and to explore challenges in treatment and reasons for possible discrepancies according to patients' view of their medication. Material and methods Anonymized data were collected from a questionnaire distributed to in‐ and outpatients and their physicians at the National Center for Epilepsy, Norway. They were asked to report AED s and dosages currently used. Additionally, 20 patients were interviewed regarding AED treatment. This information was analyzed qualitatively. Results Answers from 174 patients and their physicians were analyzed. The patients' mean age was 43 years (21–83 years), 85 (49%) were women, and 56% used AED polytherapy (2–5 AED s). For 56 patients (32%), there was a discrepancy regarding either dosage ( n = 70) or prescribed drug ( n = 32) (12%). There were discrepancies for all top 10 used drugs, with a similar distribution of patients stating lower or higher doses. Based upon interviews of 20 patients, concerns and challenges in AED treatment were addressed. Polytherapy and adverse effects which reduced the patients' quality of life were the most important obstacles for adherence to the treatment. Conclusions This study revealed that 32% of the patients had one or more discrepancies between what the physician had prescribed and what the patients actually used, in either the type or the dosages of AED s. Polytherapy, adverse effects, and poor adherence were common challenges. Improved communication and information about AED s may improve adherence and thus treatment outcome.
