About Fintepla
What is this medication?
Fintepla is a prescription oral solution used to treat seizures associated with two rare and severe types of epilepsy known as Dravet syndrome and Lennox-Gastaut syndrome. It is approved for use in patients who are at least two years of age. This medication is often added to a patient’s existing treatment plan to help further reduce the frequency of seizures when other drugs have not provided adequate control.
Due to the potential risk of serious side effects involving the heart valves and blood pressure in the lungs, Fintepla is available only through a restricted distribution program called a Risk Evaluation and Mitigation Strategy. Patients taking this medication must undergo regular heart monitoring through echocardiograms before, during, and after treatment. Although the precise mechanism is not completely known, it is thought to work by influencing serotonin levels in the brain to help decrease seizure activity.

How to read this:plans on the same formulary share tier + PA rules. Your specific plan's copay depends on (a) the tier above, (b) your plan's cost-share for that tier, (c) whether you're in the initial coverage phase or past the 2026 $2,000 out-of-pocket cap. For your exact plan, check its Summary of Benefits or log in to your Medicare.gov account. Copay cards don't apply to Medicare (federal law).
