How to Get ENDARI

ENDARI is available through prescription only.

ENDARI is a specialty medication and may not be available at your usual pharmacy.

Your physician will typically send your prescription to a specialty pharmacy that will fill your ENDARI prescription. The specialty pharmacy will contact you through a phone call to review your prescription and schedule delivery or pickup.

If you have received a physical prescription, your physician or care team will be able to provide you with information on a specialty pharmacy that can fill your prescription.
