But yes, if you click on the green button, you'll see a list of restrictions. One of those is that if you're participating in any other state or federally funded programs, yes.
The "I have been prescribed this drug" bit is also pernicious; you don't get a prescription for "insulin," you get one for Humalog or Novolog or Levemir. You are at the whim of your doctor. Used one kind for years, but suddenly lose your job, which means a change in health insurance and a change of doctor, who decides that you need to change your brand for whatever reason? You can't use this discount to help keep continuity. (Additionally I am not sure what the "or am a caregiver" requirement is legally, but should really look that one up so that I know exactly what those requirements are, so thank you for giving me something to do today...)
Or does using them disqualify people from other programs?
