Patient leaflet - Raxone

1. What Raxone is and what it is used for

Raxone contains a substance called idebenone.

Idebenone is used to treat vision impairment in adults and adolescents with an eye disease called Leber’s Hereditary Optic Neuropathy (LHON).

  • – This eye problem is inherited – this means it runs in families.

  • – It is caused by a problem with your genes (called a “genetic mutation”) that affects the ability of cells in the eye to produce the energy they need to work normally, so they become inactive.

  • – LHON can lead to loss of eyesight due to the inactivity of cells responsible for vision.

Treatment with Raxone can restore the ability of cells to produce energy and so allow inactive eye cells to work again. This can lead to some improvement in lost eyesight.
