"i have been on about 100 mg. of dexedrine for over 20 years and it always worked great until a few years ago, when my drug company stopped sending me the teva generic. i never had problems with generics before but the activis brand did nothing for me. i was told that teva was made by the same drug manufacturer that makes the name brand so i payed extra for the name brand and that does not appear to be working either. i have been told that teva no longer makes dexedrine so i am not sure what i should do. also, i was told that the fda no longer allows doses over 60 mg. but i am sure that is true. it could be my insurance company does not want to pay for more than a standard dose."
