Felbamate vs. Topamax

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

Key takeaways

Felbamate (Felbatol) and Topiramate (Topamax, Qudexy XR, Trokendi XR, Eprontia) are both antiepileptic medications, but they have some key differences. Felbamate is used to treat partial seizures in adults and seizures linked to Lennox-Gastaut syndrome (LGS) in children, while Topiramate can treat a wider range of seizures, including partial, tonic-clonic, and LGS seizures, and is also used for migraine prevention. Felbamate is typically taken 3 to 4 times a day, whereas Topiramate can be taken once or twice daily depending on the formulation. Felbamate is not a first-choice medication due to its serious side effects like liver and blood problems, while Topiramate has its own risks, such as kidney stones and serious eye problems. Both medications are available in generic forms and come in various formulations, including tablets and oral solutions. However, Topiramate offers more flexibility with extended-release options and some capsule forms can be sprinkled on food, making it easier to take for those who have trouble swallowing pills.
