OverviewDosageSide EffectsInteractionsHalf-Life

Doctors may prescribe lamotrigine (Lamictal) for anxiety when it is caused by bipolar disorder. However, it has not been FDA-approved to be used as an anxiety treatment.


A doctor will typically prescribe a low dose of lamotrigine and then steadily increase the dose over time to minimize and control side effects. The dosage may start at 25mg daily for the first two weeks. Then the dosage will increase to 50mg until up to 200mg. Always follow your doctor’s dosing schedule, as dosing may differ from patient to patient.
