Raxone in LHON: Safety

The safety and tolerability profile of Raxone administered at a dose of 900mg/day, has been well established in the RHODOS trial, which demonstrated that Raxone is generally well tolerated in patients with LHON.1,2

In addition to the Raxone safety and tolerability data from clinical trials in patients with LHON, supporting data is provided by multiple clinical studies that have investigated the safety and tolerability profile of Raxone in other indications.4–8 Doses of up to 2250 mg/day have been administered in clinical studies in other indications, demonstrating a safety profile consistent with the pivotal trial in LHON.4-6

The most commonly reported adverse reactions to Raxone are nasopharyngitis, cough, mild-to-moderate diarrhea (usually not requiring discontinuation of therapy) and back pain.9
