Abstract

Objective: To describe the profile, associated medications, potential adverse events (AE), anxiety levels, and treatment adherence among carbamazepine (CBZ) users.

Methods: Cross-sectional, descriptive, and analytical study conducted through a questionnaire and consultation of secondary data in medical records. The study was conducted in the public health system of the municipality of Ijuí.

Results: 45.9% of participants used carbamazepine for some mood disorder and 35.3% for epilepsy. 60% of the population reported adverse events, and 20% believed these were associated with the use of carbamazepine. Drowsiness (40%) and dizziness (35.3%) were the most frequent adverse events. 51.8% of participants were considered polypharmacy users. Only 3.5% of respondents were considered fully adherent to treatment.

Conclusion: It was possible to identify the profile of carbamazepine users, contributing to the understanding of the topic, given that there are few studies on this population in the literature.
