Facilitated Subcutaneous Immunoglobulin (fSCIG) from Takeda.
HyQvia is a unique facilitated subcutaneous immunoglobulin product from Takeda. By combining 10% IgG with recombinant hyaluronidase, it allows monthly large-volume subcutaneous administration — combining the convenience of monthly dosing typical of IVIG with the stable absorption and lower side-effect profile of subcutaneous administration.
HyQvia is FDA-approved for the following indications:
HyQvia is administered subcutaneously every three to four weeks. The hyaluronidase component temporarily expands the subcutaneous tissue space to accommodate larger volumes than would otherwise be possible. Most patients can self-administer at home after initial training.
The manufacturer offers a patient support program — Takeda OnePath — that can help with insurance navigation, copay assistance for eligible patients, nursing support, and ongoing education. More information is available at https://www.takedapatientsupport.com.
Treatment with HyQvia is initiated and monitored by Dr. McNeil. Prior authorizations are handled in-house — patients are not asked to navigate insurance approvals on their own. This is a subcutaneous self-administered medication. After prior authorization, the prescription is sent to a specialty pharmacy that ships the medication directly to the patient. A manufacturer-sponsored nurse or office-based training visit is typically arranged for the first dose so patients are confident with self-administration before continuing at home.
