How Much Should I Expect to Pay for KYGEVVI™ (doxecitine and doxribtimine)?

The list price¹ of KYGEVVI is $16,438.50 per carton, but the amount you will pay will largely depend on your health plan coverage.

KYGEVVI is a prescription medicine in powder form and packaged in individual packets. The powder should be dissolved in water to prepare the oral solution and taken 3 times a day with food. KYGEVVI dosing is weight-based, therefore your healthcare provider will prescribe the required number of KYGEVVI packets based on your weight. How much you pay will depend on the number or packets your healthcare provider has prescribed for you.

I Have a Health Plan Through an Employer or Private Individual Policy

What you pay for KYGEVVI will depend on your prescription drug coverage. Plans can have different out-of-pocket amounts, and most include an annual deductible and out-of-pocket maximum.

If you haven’t met your deductible, you may see higher amounts until the deductible and/or out-of-pocket maximum is met; at which point, your out-of-pocket cost should decrease.

I Have Medicare Coverage

If you have enrolled in a Medicare Advantage Plan or a standalone Part D Plan, your out-of-pocket costs can vary based on the pharmacy benefit design you are in.⁴

As of 2025, the Centers for Medicare & Medicaid Services have made changes to Medicare Part D plans to improve affordability, including allowing people with Medicare to spread their prescription drug costs throughout the year. To find out more, visit the CMS Medicare Changes website.
