Lamotrigine, commonly known by the brand name Lamictal, is an anticonvulsant medication often prescribed for individuals with bipolar disorder. This disorder affects mood, leading to periods of mania (highs) and depression (lows). Lamotrigine plays a critical role in managing the depressive episodes of bipolar disorder, which are often more frequent and severe than manic episodes.
But how successful is lamotrigine in treating bipolar disorder? In this article, we will explore its effectiveness, side effects, and how it compares to other treatment options.
What Is Lamotrigine?
Lamotrigine was initially developed as a seizure medication to treat epilepsy. However, research later showed that it was also effective in treating bipolar disorder, specifically the depressive phase of the illness. In 2003, the U.S. Food and Drug Administration (FDA) approved lamotrigine for the maintenance treatment of bipolar disorder.
Unlike other mood stabilizers, lamotrigine is particularly effective at reducing depressive episodes rather than preventing mania. This makes it a unique and essential tool in managing bipolar disorder, especially for those who experience bipolar II disorder, which involves more depressive episodes and fewer periods of mania.
How Does Lamotrigine Work?
Lamotrigine works by stabilizing mood and regulating electrical activity in the brain. In bipolar disorder, abnormal brain activity contributes to the extreme mood swings. Lamotrigine helps by blocking certain chemical signals in the brain, such as glutamate, which can overstimulate the brain’s nerve cells. By reducing these signals, lamotrigine helps to calm the brain, thus reducing mood swings, particularly depression.
It is important to note that lamotrigine is not typically used to treat acute manic episodes. Other medications, such as lithium or antipsychotics, are more effective for treating mania.
Effectiveness of Lamotrigine for Bipolar Disorder
Lamotrigine is widely considered a successful treatment for the depressive side of bipolar disorder. Studies have shown that it can reduce the frequency and severity of depressive episodes, helping individuals maintain a more balanced mood over time.
Success in Treating Bipolar Depression
Clinical trials have demonstrated that lamotrigine reduces depressive symptoms in individuals with bipolar disorder. Patients taking lamotrigine often experience fewer depressive episodes compared to those on a placebo.
One of the major benefits of lamotrigine is that it has a low risk of triggering mania. Some mood stabilizers and antidepressants used for bipolar depression can sometimes push individuals into manic episodes. Lamotrigine’s ability to manage depression without increasing the risk of mania makes it a valuable medication for long-term mood stabilization.
Long-Term Maintenance
Lamotrigine is most effective when used as part of a maintenance treatment plan. While it may not immediately alleviate symptoms during an acute depressive episode, it works well in the long run to keep mood stable. Many patients take lamotrigine as a preventative measure, significantly reducing the risk of future depressive episodes.
Lamotrigine Side Effects
Like any medication, lamotrigine comes with its own set of potential side effects. For most people, these side effects are mild and manageable. However, in rare cases, more severe reactions can occur.
Common Side Effects
The most common side effects of lamotrigine include:
Headache
Dizziness
Double vision
Nausea
Rash
Most of these symptoms tend to diminish after the first few weeks of treatment as the body adjusts to the medication.
Serious Side Effects
One of the more concerning side effects of lamotrigine is the risk of developing Stevens-Johnson syndrome (SJS), a rare but serious skin condition. SJS is characterized by a painful rash that can lead to severe complications if left untreated. The risk of SJS is higher during the first few weeks of treatment or when the dosage is increased too quickly. As a result, doctors typically start lamotrigine at a low dose and gradually increase it to reduce this risk.
If you experience a rash or other unusual symptoms while taking lamotrigine, it’s important to contact your healthcare provider immediately.

Comparing Lamotrigine to Other Bipolar Medications
Lamotrigine is just one of several medications used to treat bipolar disorder. Other common treatments include lithium, valproate (Depakote), and antipsychotic medications. Each has its own strengths and weaknesses, depending on the individual’s symptoms and needs.
Lamotrigine vs. Lithium
Lithium is one of the oldest and most well-known mood stabilizers. It is highly effective in preventing both manic and depressive episodes in bipolar disorder. However, lithium requires regular blood tests to monitor for toxicity, and some patients find it difficult to tolerate the side effects, such as weight gain, tremors, and excessive thirst.
In contrast, lamotrigine does not require regular blood tests and has a more favorable side effect profile, especially for those concerned about weight gain. However, lithium is generally more effective for preventing manic episodes, while lamotrigine is better suited for depression.
Lamotrigine vs. Antipsychotics
Antipsychotic medications like quetiapine (Seroquel) and olanzapine (Zyprexa) are often used to treat both mania and depression in bipolar disorder. While these medications are highly effective for some, they tend to have more significant side effects, including sedation, weight gain, and an increased risk of metabolic issues like diabetes.
Lamotrigine is often preferred by patients who want to avoid these side effects, as it is less likely to cause significant weight gain or sedation.
Who Should Take Lamotrigine?
Lamotrigine is most commonly prescribed for individuals with bipolar II disorder, who experience more depressive episodes than manic episodes. It is also an excellent choice for patients who have had trouble with other medications due to side effects or who are concerned about weight gain or metabolic issues.
It is important to remember that not every treatment works for every person. Some patients may not respond to lamotrigine or may experience side effects that make it difficult to continue the medication. As with any medication, it’s essential to work closely with your healthcare provider to find the treatment plan that works best for you.
Conclusion
In summary, lamotrigine is highly successful in treating the depressive episodes of bipolar disorder. Its ability to reduce depression without significantly increasing the risk of mania makes it a valuable tool for long-term management. While it is not a cure, many patients find that lamotrigine allows them to live more stable, fulfilling lives.
However, it’s important to weigh the benefits against potential side effects, especially the risk of serious skin reactions like Stevens-Johnson syndrome. For many, the pros of lamotrigine far outweigh the cons, making it a popular and effective choice for managing bipolar depression.
As always, consult with your doctor to determine if lamotrigine is the right choice for you. With the right treatment plan, living with bipolar disorder can become more manageable.
