Several companies make ambrisentan, including Gilead Sciences and Zydus Pharmaceuticals. Both companies offer financial assistance for people who take this medication.

Gilead Sciences

Gilead Sciences, which makes Letairis, offers a support program called LEAP. The support program offers:

Copay coupon

If you have commercial insurance, you might be eligible for the Letairis Co-Pay Coupon Program. Under the program, eligible patients pay as little as $5 per month for their prescription. Eligible patients are enrolled automatically when prescribed branded Letairis.

Prescription assistance

If you don’t have insurance or your insurance doesn’t cover Letairis, you might be eligible for free medication through the Letairis Patient Assistance Program.

Support for Medicare Part D beneficiaries

If your Medicare coverage doesn’t cover your Letairis costs, LEAP can identify outside sources to help pay for co-pays, coinsurance and deductibles. The program also can help you understand your out-of-pocket medication costs.

Zydus Pharmaceuticals

The Zydus Copay Savings Program helps people with commercial insurance cover out-of-pocket costs for generic ambrisentan and bosentan. If you qualify, you could receive a discounted or free prescription, up to 13 fills a year. Find out if you’re eligible for assistance.
