Alexion OneSource

Current brand pages direct healthcare offices to OneSource for connection to a Field Reimbursement Manager and customer operations for ordering/shipping questions. Support varies by prescribed product and does not establish payer approval.

The March 2025 patient form is linked by the five reviewed brand pages. It instructs email or fax of page 2 and insurance cards. Optional copay consent is subject to product-specific terms; the form is not a prescriber prescription or a REMS form.

July 2026 access guide explicitly offers OneSource enrollment by phone or email and a KOSELUGO online form. The generic /koselugo/get-started URL returned 404; no fax from another product is assigned here.

Product-specific prescription and medical-necessity form for PANTHERx Rare. Use extension 8008. This is a pharmacy intake channel, separate from OneSource enrollment.

The current brand guides publish Onco360 prescription fax and telephone. KOSELUGO guide also describes an institutional dispensing-network pathway; Onco360 is its sole contracted specialty pharmacy, not the only permissible dispensing setting. VOYDEYA uses its own prescription and REMS process.

May 2026 guide distinguishes commercial copay, a 30-day Free Trial and Free Limited Supply during qualifying coverage delays. Government-insured patients may be referred to independent resources; no foundation funding or approval is promised.

The patient form specifies letter or email to revoke authorization, unsubscribe or change services. Not a prescription or REMS channel.
