For people with difficult-to-treat seizures

Seizure control looks different from here

Introducing new PRIMAXA, the first and only orally disintegrating tablet (ODT) designed for people with refractory epilepsy.

A new and different option for families

PRIMAXA ODT is specifically designed for children and adults who have tried other antiseizure medications that didn’t work, or who struggle with other oral medications.

PRIMAXA ODT helps make daily treatment easier by removing the challenges that can stand in the way of accurate dosing. 

Dissolves on the tongue​​​

New PRIMAXA is an ODT, meaning it quickly dissolves on the tongue without having to chew or swallow. This easy-to-take formulation is ideal for people with swallowing issues.

Adjustable dosing​​​

The 50-mg and 250-mg tablets are scored (have an indented line) so you can easily split them to adjust doses as prescribed.

Convenient anytime, anywhere​​

With no refrigeration, mixing, or restorage needed, PRIMAXA ODT fits any routine at home, school, work, or on the go.

For caregivers

Bubblegum flavored for kids

PRIMAXA ODT is available in a bubblegum flavored tablet—a top flavor choice for children—and is designed to help children take their medicine as prescribed.

Did you know?

PRIMAXA ODT is made for personalized dosing to fit each person’s needs. Unlike generic versions, some doses are scored (indented) to make it easier to split tablets and adjust the dose as prescribed.
