"Tishcon obtains Orphan Drug Designation for Ubiquinol from the US FDA. The designation is for the use of Ubiquinol in the treatment of Huntington's disease. "

Above from Tishcon web site. If a drug has obtained FDA orphan drug status, one's physician may order it, even for "off label" use--ie one need not have huntington's in order to receive a prescription for the drug. Maybe some insurance companies would cover the cost of the supplement--even partial coverage would help considering the doses used in PD. Worth a try--will ask husband's MDS at December appointment.
