What is OPSUMIT used for?

How does OPSUMIT work?
OPSUMIT is an endothelin receptor antagonist. It works by blocking the effects of a protein in your body called endothelin. Doing so relaxes the blood vessels that go from your heart to your lungs and allows more blood to flow through. This lowers the amount of work your heart needs to pump blood to your lungs to get oxygen for your body. As a result, it’s easier for you to exercise and breathe.
How do I take OPSUMIT?

If you have Medicare Part D or Medicare Advantage and none of the OPSUMIT savings options are applicable or affordable for me, what can you do?
If you are insured with Medicare and the OPSUMIT drug savings options are not applicable to you and still remain unaffordable, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
The government site is easy to use and after you have selected your state, it will navigate you to the appropriate contact point to make the application. State Medicaid programs may cover the full cost of your medication.
People who qualify for both Medicare and Medicaid are called ‘dual eligibles’.
If you are denied Medicaid for OPSUMIT, and you are still unable to afford your copay or co-insurance element (for example if you are in the coverage gap or Donut Hole) then you may be eligible for a federal support program like Low Income Subsidy. To be eligible for Low Income Subsidy, you need to be a resident in one of the 50 States or the District of Columbia. You can check eligibility online at SSA Medicare D Extra Help. You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778).

If your medication is not covered by your plan, you can you can appeal your insurance company’s decision. Sometimes, a formal appeal can result in the drug being covered if it is deemed medically necessary.
