Evrysdi® 5 mg – patient leaflet, side effects, dosage

1. What Evrysdi is and what it is used for

Evrysdi contains the active substance risdiplam. It is part of a group of medicines known as ‘pre-mRNA splicing modifiers’.

Evrysdi is used to treat spinal muscular atrophy (SMA) in adults and children.

• SMA is an illness that runs in families – a genetic illness. ● It is caused by a shortage of a protein called ‘survival motor neuron’

  (SMN) in the body.

If you do not have enough SMN protein, you lose motor neurons. Motor neurons are nerve cells that control muscles.

• This leads to muscle weakness and wasting.

• This can make everyday movements difficult, such as head and

  neck control, sitting, crawling and walking.

• The muscles used for breathing and swallowing may also become

  weaker.

How Evrysdi works

Evrysdi works by helping the body produce more SMN protein. ● This means you lose fewer motor neurons – this may improve how

well muscles work in people with SMA.

In infants with SMA Type 1, Evrysdi may:

• increase how long they live
• reduce the need for a ventilator to help with breathing ● help them be able to keep being fed by mouth.

In children (toddlers to adolescents) and adults with SMA Type 2 and 3, Evrysdi may:

• stop muscle control getting worse
• improve muscle control.
