About EVRYSDI
What is this medication?
Evrysdi is a prescription medicine used to treat spinal muscular atrophy, commonly known as SMA, in both adults and children. SMA is a rare genetic disorder that affects the nerve cells in the spinal cord, leading to progressive muscle weakness and loss of movement. This medication works by helping the body produce more of the survival motor neuron protein, which is vital for the health and survival of the nerve cells that control muscle movement.
This treatment is a liquid medication that is taken once daily by mouth or through a feeding tube, making it the first at-home oral therapy for this condition. It is approved for use in patients of all ages, including infants. By increasing the levels of necessary proteins throughout the central nervous system and the rest of the body, Evrysdi aims to improve motor function and help individuals with SMA maintain their physical strength and independence.

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).
