The Archways program offers a United Therapeutics Virtual Patient Educator to support patients as they begin their journey with TYVASO

The Archways program offers a variety of educational resources including a Virtual Patient Educator, available at no cost for patients starting treatment with TYVASO, and their caregivers.

Once they’ve been prescribed TYVASO, patients can enroll in the Archways program. Patients will then be contacted by a United Therapeutics Patient Educator to talk one-on-one via phone or video chat, to review:

  • Disease information
  • Details about starting TYVASO
  • Questions about how to use the device
  • What to expect when getting started in the Specialty Pharmacy process

To get started:

United Therapeutics and the Archways program do not provide medical advice. Patients are advised to consult with their HCP with any specific questions or concerns about their treatment.

Hospital access support

The TYVASO Institutional Starter Kit (ISK) has all of the materials you need to initiate TYVASO therapy in the hospital setting, including enough medication for 4 days of therapy.

If additional medication is needed, 4-packs of medication ampules are available for order separately.

The ISK is for single-patient use only and includes:

  • 2 TYVASO Inhalation Systems (devices)
  • All required assembly components (plastic accessories, medicine cups, and 3 power sources for operation)
  • One 4-pack of TYVASO medication ampules
  • TYVASO Inhalation System Instructions for Use manual

Steps to access the ISK:

  • Contact the selected Specialty Pharmacy to set up a new wholesale account, which can take a few days to activate, or to place wholesale purchase order
  • Your order will be shipped directly to the hospital from the Specialty Pharmacy

IMPORTANT: To help avoid extended hospital stays due to time required for outpatient insurance approval, it is important to complete a TYVASO Referral Form if the patient is going to continue taking TYVASO after discharge.
