About WINREVAIR
What is this medication? Winrevair is a prescription medicine used to treat adults who have pulmonary arterial hypertension, which is often abbreviated as PAH. This condition involves high blood pressure in the arteries of the lungs, making it difficult for the heart to pump blood through the body. The primary goals of using this medication are to increase exercise capacity, improve the patient's functional ability, and reduce the likelihood of the disease getting worse over time.
The medication works by targeting specific signaling pathways in the body to help restore the balance between the growth and death of cells in the blood vessels of the lungs. Unlike some other treatments that only widen blood vessels, this drug addresses the structural changes associated with the disease. It is administered as an injection under the skin every three weeks and is typically used alongside other standard treatments to help manage the symptoms of the condition.

How to read this:plans on the same formulary share tier + PA rules. Your specific plan's copay depends on (a) the tier above, (b) your plan's cost-share for that tier, (c) whether you're in the initial coverage phase or past the 2026 $2,000 out-of-pocket cap. For your exact plan, check its Summary of Benefits or log in to your Medicare.gov account. Copay cards don't apply to Medicare (federal law).
