I take a shot for multiple sclerosis. This costs $5300 every month!!!! Thank goodness, it is covered by Medicare, although I still have to pay about $4000+ annually, but the cost has gone from under $2000 to $3500 to $4900 to $5300 in the space of 10 years. They can't claim the costs are because of research an development, as this shot is the same one I have had for a decade. The only thing that has changed in that time is that the company has been bought by 3 different companies, the latest one Bayer. This upsets me every time I use this medication.
