while most people with Medicare Part D {and othere government sponsored insurances, like DoD, Medicaid, etc} are exempted from traditional pharmaceutical company assistance programs, there are solutions.

Most MS drug Rx companies have other mechanisms & programs to get you the financial/drug assistance. It is often via funneling the request for assistance to a nonprofit org (that they may help fund)

Don't let finances stop you- there is help out there and it os not as coplicated or hopeless as it may seem.
