Insights
Pediatric patients on antiepileptic drugs (AEDs) frequently experience adverse drug reactions (ADRs). Polytherapy increased ADRs but also improved seizure control, highlighting the need for careful pharmacovigilance in children.
Area of Science:
- Pediatric Neurology
- Clinical Pharmacology
- Epileptology
Background:
- Epilepsy affects a significant pediatric population.
- Antiepileptic drugs (AEDs) are a cornerstone of epilepsy management.
- Understanding adverse drug reactions (ADRs) in children is crucial for safe and effective treatment.
Purpose of the Study:
- To investigate the occurrence and types of adverse effects of antiepileptic drugs (AEDs).
- To compare ADRs in pediatric epileptic patients receiving monotherapy versus polytherapy.
- To assess the relationship between AED therapy and seizure control.
Main Methods:
- Eighty pediatric patients (≤18 years) with epilepsy on stable AED doses for at least three months were evaluated.
- Patients underwent interviews and detailed questionnaires regarding experienced adverse drug reactions (ADRs).
- Data were analyzed comparing outcomes between monotherapy and polytherapy groups.
Main Results:
- 97% of pediatric patients reported experiencing AED-related ADRs.
- Polytherapy was associated with a higher incidence of ADRs (e.g., fatigue, hair loss) compared to monotherapy (e.g., fatigue, somnolence).
- Patients on polytherapy showed a statistically significant improvement in seizure frequency.
Conclusions:
- Children on polytherapy are more prone to ADRs than those on monotherapy.
- Despite increased ADRs, polytherapy can lead to better seizure control in pediatric epilepsy.
- Robust pharmacovigilance is essential for early identification and management of ADRs in children using AEDs.
Objective:
To investigate the occurrence of adverse effects of antiepileptic drugs (AEDs) in pediatric epileptic patients on mono- or polytherapy.
Method:
We evaluated eighty consecutive patients that met the following inclusion criteria: aged ≤18 years; diagnosed with epilepsy for at least one year; a stable dose of AED for at least three months; verbal consent to participation in the study. Patients were asked if they had experienced any adverse drug reaction (ADR) related to the AED. Afterward, regardless of the answer, they were interviewed based on a detailed semi-structured questionnaire about the presence of ADRs associated with the AED. The data were analyzed regarding the use of monotherapy or polytherapy.
Results:
Ninety-seven percent of the patients reported having experienced ADRs related to AEDs. The greatest number of seizures affected the group of patients treated with monotherapy (both at baseline and at followup), but the greatest number of ADRs were observed among patients treated with polytherapy. In patients on monotherapy, the most frequent ADRs reported at baseline included fatigue and somnolence, and among patients with polytherapy, it was fatigue and hair loss.
Conclusion:
Children on polytherapy were significantly more likely to develop ADRs compared to those on monotherapy, but a statistically significant improvement in seizure frequency was also observed in the group of patients on polytherapy. Pharmacovigilance is very important in children with AEDs, so that ADRs can be identified early and managed appropriately.

This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
