Epilepsy Home > Lamictal Weight Change

Some people who are taking Lamictal® (lamotrigine) may notice a weight change. Specifically, the drug has been shown to cause weight gain.
In clinical studies, between 1 and 5 percent of people taking Lamictal for bipolar disorder experienced weight gain. However, weight gain was not reported as a side effect in people taking the medication to control seizures.
If you are taking Lamictal and weight changes occur, contact your healthcare provider. He or she may give you some suggestions for taking the pounds off, such as eating heart-healthy foods, exercising, and limiting your intake of alcohol. Your doctor may recommend another medication instead.
