Lamotrigine

This test monitors lamotrigine (an epilepsy and mood stabilizer medication) levels to ensure therapeutic efficacy and prevent toxicity.

Patients prescribed lamotrigine for epilepsy or bipolar disorder should undergo periodic monitoring.

A blood sample is drawn, usually before taking the daily dose to measure the lowest (trough) level.

Low levels may reduce effectiveness, while high levels can lead to toxicity, including dizziness, rashes, and liver issues.

Yes, certain drugs, like valproate and birth control pills, can alter lamotrigine metabolism.
