Lamictal is a medication prescribed to treat epilepsy, bipolar disorder, and other mental health conditions. It is known to be effective in managing symptoms, but like any medication, it can come with potential side effects. Long-term use of Lamictal has been associated with a range of side effects that can impact an individual’s quality of life. In this article, we will explore the long-term side effects of Lamictal in detail.

Common Side Effects

The most common side effects of Lamictal include dizziness, headache, nausea, and fatigue. These side effects are usually mild and go away on their own after a few days or weeks of starting the medication. However, if they persist or become severe, it is important to talk to your doctor.

Less Common Side Effects

In addition to the common side effects, Lamictal can also cause less common side effects that may persist over the long term. These include:

1. Skin Rash

A skin rash is the most common Lamictal side effect. It typically occurs within the first eight weeks of treatment, but it can develop at any time. In rare cases, it can be severe and life-threatening. If you develop a rash while taking Lamictal, notify your doctor immediately.

2. Mood Changes

Lamictal is used to treat mood disorders, but it can also cause mood changes in some people. These changes can include depression, anxiety, irritability, and even suicidal thoughts. If you experience any mood changes while taking Lamictal, talk to your doctor right away.

3. Cognitive Impairment

Long-term use of Lamictal can cause cognitive impairment, which can affect memory, attention, and other cognitive functions. This side effect is more common in older adults who take high doses of the medication.

4. Weight Gain

Weight gain is a common side effect of many medications, including Lamictal. It can be particularly challenging for individuals with bipolar disorder who are already at risk for weight gain due to their condition.

Rare Side Effects

While rare, Lamictal can also cause serious long-term side effects. These include:

1. Liver Damage

Lamictal can cause liver damage in some people, which can be serious or even life-threatening. Symptoms of liver damage include jaundice, abdominal pain, and fatigue. If you experience any of these symptoms, seek medical attention immediately.

2. Blood Disorders

Long-term use of Lamictal can cause blood disorders, such as anemia and low platelet count. These disorders can increase the risk of bleeding and infections.

3. Vision Problems

In rare cases, Lamictal can cause vision problems, such as blurred vision, double vision, and eye pain. If you experience any vision problems while taking Lamictal, notify your doctor right away.


Long-term use of Lamictal can come with a range of potential side effects, some of which can be serious. If you are taking Lamictal, it is important to be aware of these side effects and to talk to your doctor if you experience any symptoms. Your doctor can help you manage these side effects and ensure that you are getting the best possible treatment for your condition.
