How does this medication work? What will it do for me?
Idebenone belongs to the group of medications called ATP production modulators. It is used to treat Friedreich's Ataxia, an inherited condition that causes progressive damage to the nervous system.
The symptoms of Friedreich's Ataxia range from difficulty walking to speech problems and heart disease. The exact way that idebenone works is not known at this time, but it is believed to increase the supply of energy to cells in the body and may protect cells that are damaged by Friedreich's Ataxia.
Idebenone has been granted a notice of compliance with conditions (NOC/c) by Health Canada. This means that Health Canada has approved this medication to be marketed based on promising evidence of effectiveness, but additional results of studies are needed to verify its effectiveness. An NOC/c is used to allow access to products that are used for the treatment or prevention of serious, life-threatening or severely debilitating illness.

How should I use this medication?
The usual staring dose of idebenone ranges from 150 mg (for people who weigh 45 kg or less) to 300 mg (for people who weigh over 45 kg) taken 3 times daily. After 6 months, your doctor may increase the dose to 450 mg (for people who weigh 45 kg or less) or 750 mg (for people who weigh more than 45 kg) taken 3 times daily. If no additional benefit or improvement is seen with the higher dose after 6 months, the dose should be reduced to the original starting dose.

If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
The tablets should be swallowed whole with water. Do not break or chew the tablets. Food increases the amount of medication absorbed and available for the body to use. For this reason, it should be taken with food.
