<p>
Therapeutic use or overdose of tramadol has been associated with seizure. However, it is unknown if there are any specific predisposing factor that increases a patient’s risk of seizure after tramadol use/overdose.</p>
<p>
In a recently published study, eighty patient data with single ingestion of tramadol were reviewed.</p>
<ul>
<li>
52.5% of the patient developed seizure</li>
<li>
11% developed serotonin syndrome</li>
</ul>
<p>
</p>
<p>
Risk of seizure</p>
<ul>
<li>
Higher risk of seizure were found in Asian patients (OR=7.1, 95% CI: 1.9 – 27.3) and patients with abuse/misuse of tramadol (OR=3.2, 95% CI: 1.2-8.3)</li>
<li>
Patients who presented with opioid toxidrome were less likely to develop seizure (OR=0.12, 95% CI: 0.02 – 0.71) </li>
<li>
Acute overdose and age were not associated with increased risk of seizure.</li>
</ul>
<p>
</p>
<p>
<strong>Conclusion</strong></p>
<p>
In this small study, Asian patients and patients with abuse/misuse were at higher risk of developing seizure compared to patients who overdose tramadol.</p>
