Lamotrigine Level

Lamotrigine Level

The Lamotrigine Level test measures the amount of lamotrigine, a medication used to treat seizures and bipolar disorder, in your blood. Lamotrigine belongs to a class of medications called anticonvulsants. It works by decreasing abnormal electrical activity in the brain. The purpose of this test is to ensure that you're receiving the proper dosage of the drug: too low, and your symptoms may not be adequately controlled; too high, and you may experience adverse side effects. The test is often ordered after the start of a lamotrigine regimen, after a change in dosage, or if side effects or a recurrence of symptoms occur.

Why is the Lamotrigine Level test done?

The Lamotrigine Level test is done to monitor the amount of lamotrigine in the blood to ensure that it is within the therapeutic range that helps control symptoms without causing side effects.

What do the test results mean?

The results are given in micrograms per milliliter (mcg/mL). The therapeutic range for lamotrigine when used for epilepsy is typically considered to be about 3-14 mcg/mL. If levels are too high, it might cause side effects; if levels are too low, it may not effectively control your symptoms.
