i crossed the border into the USA on the weekend. They sell it in 400 milligram capsules. In Canadian drug stores we can only get 100 milligram capsules! If Dad has to take say 1200 milligrams a day, 3 pills is way easier for him to take than 12 with all the swallowing and choking issues!!
Before we discuss this with his neurologist, I would be VERY interested in hearing from PSP patients or their caregivers about their experience with it.
