Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Zonisamide (Zonegran, Zonisade) and Rufinamide (Banzel) are both antiepileptic medications, but they are used for different types of seizures. Zonisamide is used to control partial-onset seizures in people with epilepsy and is available in both capsule and oral suspension forms. Rufinamide, on the other hand, is specifically used for seizures linked to Lennox-Gastaut syndrome (LGS) and is available as tablets and an oral suspension. Zonisamide can be taken once a day, while Rufinamide must be taken twice a day with food for full absorption. Zonisamide capsules are available as a lower-cost generic, but Rufinamide can be expensive even in its generic form. Both medications can cause drowsiness and dizziness, but Rufinamide also has a risk of heart rhythm problems. Additionally, Zonisamide should not be taken if you have a sulfa allergy, while Rufinamide is contraindicated for those with Familial Short QT syndrome.
