BioMarin Clinical Coordinators provide ongoing one-on-one product support and PKU education when you need it—in person, by phone or text, or via email, to help you:. Stay informed about PKU management by attending an event or watching a live event on Facebook. If you attend an in-person event, you can meet other people living with PKU, learn about PKU management, and build your circle of support. BioMarin is committed to helping reduce the financial issues that can come between you and your treatment. It covers co-pay costs related to both a PALYNZIQ prescription and up to 3 refills of auto-injectable epinephrine prescriptions, up to the annual maximum, for as long as you remain eligible. This program is only available for commercially-insured patients.
