Specialty Pharmacy

Working with the Specialty Pharmacy

TYVASO is available only through Specialty Pharmacies, which focus on providing you with in-home training and 24-hour support. Your Specialty Pharmacy (SP) provider is part of your healthcare team.

What happens next: Your SP provider will call you. Answer the call: When they first reach out to you, the SP provider will call you from an 866 or 877 number that you may not recognize. Since they cannot get the medicine to you unless they speak to you, be sure to answer the call to get started and to stay on track.

An SP nurse will give you personal instructions on using TYVASO and provide ongoing support. Your SP nurse may visit or call regularly as you are getting comfortable using TYVASO.

Here’s what to expect when starting TYVASO:


Your doctor will send a referral for your TYVASO prescription to a Specialty Pharmacy. Your SP provider is part of your healthcare team and focuses on providing you with in-home training and 24-hour support.


Your SP provider will process your referral and contact your insurance company to determine and verify coverage for you.


Your SP provider will contact you to review your coverage and benefits, and if you don’t have insurance, they can help you explore other financial options. Once your referral is approved, they will work with you to coordinate delivery of TYVASO.

Delivery and Demonstration

Your SP nurse will contact you to schedule a virtual or in-person appointment at your home to teach you how to use TYVASO. Your TYVASO system and supplies will be delivered a couple of days before your appointment.

Follow-up and Refills

Your SP nurse can arrange follow-up visits to support you as you get used to using TYVASO. Every 4 weeks, you’ll receive a refill shipment of supplies.
