• Monitoring: Continuous monitoring of vital signs, cardiac rhythm, and neurological status is essential. Electrocardiograms (ECGs) may be performed to assess for any cardiac arrhythmias.
• Fluid Resuscitation: Intravenous fluids may be administered to maintain hydration and support blood pressure.

Specific Antidotes and Treatments

1. Symptomatic Treatment

• Seizure Management: Benzodiazepines (e.g., lorazepam or diazepam) are often used to control seizures. If seizures persist, additional antiepileptic medications may be required.
• Support for Respiratory Depression: If respiratory depression occurs, supplemental oxygen or mechanical ventilation may be necessary.

2. Specific Antidotes

• Currently, there are no specific antidotes for mixed antiepileptic poisoning. Treatment is primarily supportive and symptomatic.

Long-term Management

1. Psychiatric Evaluation

• If the poisoning is suspected to be intentional, a psychiatric evaluation is essential to address underlying mental health issues and prevent future incidents.

2. Medication Review

• A comprehensive review of the patient's medication regimen is necessary to identify potential drug interactions or inappropriate prescribing practices. Adjustments may be made to optimize the patient's treatment plan.

3. Patient Education

• Educating patients and caregivers about the risks associated with antiepileptic medications, including the importance of adherence to prescribed dosages and the dangers of mixing medications, is vital for preventing future poisoning incidents.
