Before taking Evrysdi
Before taking Evrysdi, tell your healthcare provider about all of your medical conditions, including if you:

Evrysdi (risdiplam) and Spinraza (nusinersen) work in different ways to increase the level of functional SMN (survival of motor neuron) protein in people with spinal muscular atrophy (SMA). A key difference between the two drugs is that Evrysdi is taken orally, whereas Spinraza needs to be given via intrathecal injection. Continue reading
At least four major trials have reported that Evrysdi significantly improves survival motor neuron (SMN) protein levels in children and adults with SMA, allowing an increase in muscle strength and the achievement of milestones, such as being able to sit independently for 5 or more seconds at a time. Continue reading
Evrysdi does not cure spinal muscular atrophy (SMA), it just replaces a protein that is low or missing in children or adults with the condition, improving muscle strength and allowing some relief from some of the symptoms of SMA. Evrysdi must be taken for a person’s lifetime; if Evrysdi is stopped the child or adult’s SMA symptoms will progressively worsen at a faster rate. Continue reading
Evrysdi (risdiplam) works by targeting the SMN2 gene (survival motor neuron gene 2), causing it to make more functional SMN protein. This increases SMN protein levels throughout the central nervous system and body, helping to improve motor nerve and muscle function in children and adults with SMA. Continue reading
