Complete patient guide for uses, dosage, side effects, and safety information
Quick Facts
What Is Camzyos Used For?
Camzyos is a medication that helps manage a specific heart condition known as obstructive hypertrophic cardiomyopathy (HCM).
Primary Uses
It is primarily used to treat adults suffering from symptomatic obstructive hypertrophic cardiomyopathy, a condition where the heart muscle thickens, making it difficult for blood to flow out of the heart.
How It Works
Camzyos works by reducing excessive contraction of the heart muscle, thereby easing the obstruction to blood flow, which may improve symptoms and exercise capacity.
Good to know: Camzyos is not considered addictive.
