Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Lamotrigine (Lamictal) and Levetiracetam (Keppra) are both antiepileptic medications used to treat seizures, but they have some key differences. Lamotrigine is available in both immediate-release and extended-release forms and can also be used to treat bipolar disorder, while Levetiracetam is available in immediate-release and extended-release forms but is not used for bipolar disorder. Lamotrigine can cause serious skin reactions like rash, and its dose needs to be increased slowly to avoid these side effects. On the other hand, Levetiracetam is known for causing mood changes and behavioral issues, especially in children, and does not interact with food or other medications. Both medications are available in generic forms, but Lamotrigine has more interactions with other medications, such as birth control pills and valproic acid.
