Overview
Lamictal (lamotrigine) is a mood stabilizer approved for maintenance treatment of bipolar disorder to delay mood episodes. Unlike many other bipolar medications, Lamictal is especially effective for the depressive side of bipolar disorder. It's generally well-tolerated and doesn't cause the weight gain common with other mood stabilizers. At Next Step Psychiatry, we frequently prescribe Lamictal as a foundational treatment for bipolar disorder.
How Lamictal Works
Lamotrigine works by blocking voltage-sensitive sodium channels and inhibiting the release of excitatory neurotransmitters like glutamate. This stabilizes neural membranes and helps prevent the mood swings characteristic of bipolar disorder. Its unique mechanism makes it particularly effective for preventing bipolar depression.

Frequently Asked Questions
Why does Lamictal need to be started so slowly?
Slow titration dramatically reduces the risk of serious skin rashes, including Stevens-Johnson syndrome. The standard titration takes 6 weeks to reach therapeutic doses. This is a safety requirement, not a choice.
What should I do if I get a rash on Lamictal?
Any rash while starting or taking Lamictal requires immediate medical evaluation. While most rashes are benign, serious reactions can occur. Do not dismiss any rash - contact your provider or seek emergency care immediately.
Is Lamictal better for bipolar depression or mania?
Lamictal is primarily effective for preventing and treating bipolar depression. It's less effective for preventing or treating manic episodes. Many patients need an additional medication for manic symptoms.
