Dr. Warren initially prescribed steroids but they didn’t work and had overwhelming side effects. He then prescribed idebenone. Within a week of taking idebenone I woke up and saw colors. It was like a light switch. I went from grey to color. I am now able go out to museums with my caregiver who prepares it for me every morning. As Zenia will attest, it has been a miracle for me. I cannot say enough. Idebenone has been a life changer.
