About CAMZYOS
What is this medication? CAMZYOS, which contains the active ingredient mavacamten, is a prescription medicine used to treat adults with a specific heart condition known as symptomatic obstructive hypertrophic cardiomyopathy. This condition occurs when the heart muscle thickens, making it difficult for the heart to pump blood out to the rest of the body. The medication works by targeting the heart muscle directly to reduce the obstruction that limits blood flow, helping the heart function more efficiently.
The main purpose of this treatment is to improve functional capacity and reduce symptoms such as shortness of breath and fatigue in people with this condition. It is classified as a cardiac myosin inhibitor, a type of drug that helps decrease the excessive contraction of the heart muscle. Because the medication affects how the heart pumps, patients typically require regular monitoring and specific heart imaging tests while taking it to ensure safety and effectiveness.

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).
