I have been on the injected drug for several months. I have a rare bone disease which is causing my skull to collapse.When I got put on Silverscript, they refused pay for it because it is expensive! I have to take this medication or my skull will collapse and I will die!! Silverscript keeps making up excuses why they have to keep reviewing the matter. All the time I am dying because of it!! User's recommendation: Choose another prescription plan or you might die!!
