Idebenone (idebenone) — Uses, Dosage, Side Effects & Safety

Drug class: General Medical Info

Overview

Idebenone is a prescription medication used primarily to treat Leber’s Hereditary Optic Neuropathy (LHON), a rare genetic disorder that causes sudden vision loss. It is also being studied for other mitochondrial and neurodegenerative diseases. Idebenone works by supporting the function of mitochondria, the energy-producing structures in your cells. It acts as an antioxidant, helping to protect nerve cells from damage caused by oxidative stress. Patients should know that idebenone is not a cure for LHON, but it may help slow or partially reverse vision loss if started early. It is important to take the medication exactly as prescribed and to attend regular follow-up appointments to monitor progress and side effects.
